FOS v7.3 enhances FCP probing for devices connected to a port with ALPA 0xC0 and 0x40 to obtain the device
information for NS entry.
For base devices that logged in with ALPA 0xC0 and 0x40, FOS v7.3 provides the ability to update NS entries
when these base devices perform logout. Administrators can turn on this update mode to ensure NS and login
database consistency with “F-port Device Update Mode” option under the “Fabric parameters” section of the
configure CLI. This option can only be changed when a switch is disabled.
NPIV Base Device Logout Enhancements
FOS v7.3 enhances NPIV by allowing NPIV devices remain logged in on a port to a fabric when the base device
on the same port performs a logout. Administrator can configure this feature via the portCfgFlogiLogout CLI.

FOS v7.3 enhances back-end credit loss detection and recovery to back-end links on FX8-24 with the existing
CLI command creditRecovMode.
aptPolicy change
FOS v7.3 deprecates AP policy related configuration from the CLI command aptPolicy. AP policy is used only by
FR4-18i blade, which is not supported since FOS 7.1.
slotPowerOn and slotPowerOff enhancement
FOS v7.3 supports slotPowerOn and slotPowerOff command on core blades in a DCX/DCX-4 or DCX 8510/DCX
8510-4 chassis. Administrators can use this command to power on or off a core blade without physical
presence.
Port Transition from Persistent Disabled to Disabled
FOS v7.3 supports directly transition a persistently disabled port to the disabled state without having to
persistently enable the port first. Administrator can configure this option via the new portCfgPersistence
command
portBeacon Change
FOS v7.3 enhances the portBeacon command to list all beaconing ports in a switch (via -all option).
ethif Command
FOS v7.3 introduces a new CLI command ethif to manage the switch Ethernet management interfaces. With

Adaptive Networking with QoS—Adaptive Networking provides a rich framework of capability allowing a user to
ensure high priority connections obtain the bandwidth necessary for optimum performance, even in congested
environments. The QoS SID/DID Prioritization and Ingress Rate Limiting features are the first components of
this license option, and are fully available on all 8Gb and 16Gb platforms.
Note :
With FOS v7.2, the Adaptive Networking license has become part of the base FOS firmware, and
features under this license no longer require the license to be installed. Customers that wish to have
these capabilities without purchasing the license are required to upgrade to FOS v7.2 or later.
Brocade 6520 does not require the Adaptive Networking with QoS license to enable the capabilities
associated with this license. These capabilities are included by default on the Brocade 6520.
Server Application Optimization — When deployed with Brocade Server Adapters, this license optimizes overall
application performance for physical servers and virtual machines by extending virtual channels to the server
infrastructure. Application specific traffic flows can be configured, prioritized, and optimized throughout the
entire data center infrastructure. This license is not supported on the Brocade 8000.
Note :
With FOS v7.2, Server Application Optimization license has become part of the base FOS firmware,

tunnels and also for advanced capabilities like tape read/write pipelining.
ICL 16-link, or Inter Chassis Links -- This license provides dedicated high-bandwidth links between two Brocade
DCX chassis, without consuming valuable front-end 8Gb ports. Each chassis must have the 16-link ICL license
installed in order to enable the full 16-link ICL connections. (Available on the DCX only.)
ICL 8-Link – This license activates all eight links on ICL ports on a DCX-4S chassis or half of the ICL bandwidth
for each ICL port on the DCX platform by enabling only eight links out of the sixteen links available. This allows
users to purchase half the bandwidth of DCX ICL ports initially and upgrade with an additional 8-link license to
utilize the full ICL bandwidth at a later time. This license is also useful for environments that wish to create ICL
connections between a DCX and a DCX-4S, the latter of which cannot support more than 8 links on an ICL port.
Available on the DCX-4S and DCX platforms only.
ICL POD License – This license activates ICL ports on core blades of DCX 8510 platforms. An ICL 1st POD
license only enables half of the ICL ports on CR16-8 core blades of DCX 8510-8 or all of the ICL ports on
CR16-4 core blades on DCX 8510-4. An ICL 2nd POD license enables all ICL ports on CR16-8 core blades on a
DCX 8510-8 platform. (The ICL 2nd POD license does not apply to the DCX 8510-4.)
Enterprise ICL (EICL) License – The EICL license is required on a Brocade DCX 8510 chassis when that chassis
is connected to four or more Brocade DCX 8510 chassis via ICLs.
Note that this license requirement does not depend upon the total number of DCX 8510 chassis that exist in a
fabric, but only on the number of other chassis connected to a DCX 8510 via ICLs. This license is
recognized/displayed when operating with FOS v7.0.1 but enforced with FOS v7.1.0 or later.
Note: The EICL license supports a maximum of nine DCX 8510 chassis connected in a full mesh
topology or up to twelve DCX 8510 chassis connected in a core-edge topology. Refer to the Brocade
SAN Scalability Guidelines document for additional information.
WAN Rate Upgrade 1 License – The WAN Rate Upgrade 1 license provides the additional WAN throughput up to
10 Gbps on Brocade 7840. The base configuration of Brocade 7840 without the WAN Rate Upgrade 1 license
provides WAN throughput up to 5 Gbps.
![Page 18: v7.3.0_releasenotes_v2.0](https://reader036.vdocuments.us/reader036/viewer/2022082213/55cf94d1550346f57ba499d0/html5/thumbnails/18.jpg)
Fabric OS v7.3.0 Release Notes v2.0 Page 18 of 114
WAN Rate Upgrade 2 License – The WAN Rate Upgrade 2 license provides unlimited WAN throughput (other
than the hardware limit) on Brocade 7840. The WAN Rate Upgrade 2 licenses also enable the use of two
40GbE ports on Brocade 7840. The 40GbE ports cannot be configured without the WAN Rate Upgrade 2
license. A WAN Rate Upgrade 1 license must be installed on a Brocade 7840 before a WAN Rate Upgrade 2
license is installed. A WAN Rate Upgrade 1 license cannot be removed before the WAN Rate Upgrade 2 license
has been removed.
Note: The WAN Rate Upgrade 1 and WAN Rate Upgrade 2 licenses apply only to Brocade 7840. They
control the aggregate bandwith for all tunnels on a Brocade 7840. The entire capacity controlled by
the licenses can be assigned to a single tunnel subject to hardware limitation, or a portion of the
capacity can be assigned to multiple tunnels. The total bandwidth aggregated for all tunnels should
not exceed the limits established by the licenses.

FOS Migration Considerations
This section contains important details to consider before migrating to or from this FOS release.
FOS Upgrade and Downgrade Special Considerations
DCX/DCX-4S units running any FOS v7.2.x can be non-disruptively upgraded to FOS v7.3.0. This upgrade is
non-disruptive to both FC and FCoE traffic (when using FCOE10-24 blades).
Any firmware activation on Brocade 7800, or DCX, DCX-4S, DCX 8510-8, DCX 8510-4 with FX8-24 will
disrupt I/O traffic on the FCIP links.
Disruptive upgrades to Fabric OS v7.3.0 are allowed and supported from FOS v7.1.x (up to a two-level
migration) using the optional “-s” parameter with the firmwaredownload command.
If there are multiple node EGs (encryption groups) in a fabric, please complete firmwaredownload on one node
at a time before downloading on another node.
Recommended Migration Paths to FOS v7.3.0
Migrating from FOS v7.2
Any 8G or 16G platform running any FOS v7.2.x firmware can be non-disruptively upgraded to FOS v7.3.0.
Migrating from FOS v7.1
Any 8G or 16G platform operating at FOS v7.1.x must be upgraded to FOS v7.2.x before non-disruptively
upgrading to FOS v7.3.0.
Disruptive upgrade to FOS v7.3.0 from FOS v7.1 is supported.

It is important to note that host SMI-S agents cannot be used to manage switches running FOS v7.3.
If users want to manage a switch running FOS v7.3 using SMI-S interface, they must use Brocade
Network Advisor’s integrated SMI agent.
Fabric OS Compatibility
The following table lists the earliest versions of Brocade software supported in this release, that is, the earliest
supported software versions that interoperate. Brocade recommends using the latest software versions to get
the greatest benefit from the SAN.
To ensure that a configuration is fully supported, always check the appropriate SAN, storage or blade server
product support page to verify support of specific code levels on specific switch platforms prior to installing on
your switch. Use only FOS versions that are supported by the provider.
For a list of the effective end-of-life dates for all versions of Fabric OS, visit the following Brocade Web site:

Zoning Compatibility Note:
Users are recommended to upgrade to the following versions of firmware when interoperating with a switch
running FOS v7.0 or later in the same layer 2 fabric to overcome some of the zoning operations restrictions
that otherwise exist:
Main code level Patch code levels with full zoning
compatibility
FOS v6.2 FOS v6.2.2d or later
FOS v6.3 FOS v6.3.2a or later
![Page 26: v7.3.0_releasenotes_v2.0](https://reader036.vdocuments.us/reader036/viewer/2022082213/55cf94d1550346f57ba499d0/html5/thumbnails/26.jpg)
Fabric OS v7.3.0 Release Notes v2.0 Page 26 of 114
FOS v6.4 FOS v6.4.1 or later
If there are switches running FOS versions lower than the above listed patch levels in the same fabric as a
switch with FOS v7.0 or later, then cfgsave and cfgenable operations initiated from these switches will fail if
the zoning database is greater than 128KB. In such scenarios zoning operations such as cfgsave/cfgenable
can still be performed successfully if initiated from a switch running FOS v7.0 or later.

Notes:
1. When 2+2 power supply combination is used, the users are advised to configure the Fabric Watch setting for
switch marginal state to be two power supplies. Users can use the CLI switchstatuspolicyset to configure this
value if the current value is set to zero. In FOS v7.0.x, the default setting for the marginal state due to missing
power supplies is incorrectly set to zero, which will prevent Fabric Watch from generating notifications when the
switch enters the marginal state due to missing power supplies
2. Power supply requirements for a 512 port configuration without the use of ICLs will be reduced to two (1+1) in a
future 7.3.0x patch release.

Scalability
All scalability limits are subject to change. Limits may be increased once further testing has been completed,
even after the release of Fabric OS. For current scalability limits for Fabric OS, refer to the Brocade Scalability
Guidelines document, available under the Technology and Architecture Resources section at
http://www.brocade.com/compatibility
Other Important Notes and Recommendations
Note: Please note that most content in this section is primarily applicable to FOS v7.2.1a firmware and has not
been completely updated for FOS v7.3.0. Contents of this section may or may not be entirely applicable to FOS
v7.3.0 firmware.
Adaptive Networking/Flow-Based QoS Prioritization
Any 8G or 4G FC platform running FOS v6.2.2e or lower version of firmware cannot form an E-port
with a 16G FC platform when Adaptive Networking QoS is enabled at both ends of the ISL. Users must
disable QoS at either end of the ISL in order to successfully form an E-port under this condition.
Users can disable QoS via portcfgQos --disable command. Please consult Fabric OS Command
Reference manual for details related to portcfgQoS command.
When using QoS in a fabric with 4G ports or switches, FOS v6.2.2 or later must be installed on all 4G
products in order to pass QoS info. E_Ports from the DCX to other switches must come up AFTER
6.2.2 is running on those switches.
When FOS is upgraded from v7.1.x to v7.2.0 or later:
If the Adaptive Networking license was NOT installed in v7.1.x, all ports will have QOS disabled
following the firmware upgrade and links will come up in normal mode.
If the Adaptive Networking license was installed in v7.1.x, there will be no change in port QOS
mode following the upgrade.
![Page 41: v7.3.0_releasenotes_v2.0](https://reader036.vdocuments.us/reader036/viewer/2022082213/55cf94d1550346f57ba499d0/html5/thumbnails/41.jpg)
Fabric OS v7.3.0 Release Notes v2.0 Page 41 of 114
If the remote port supports QOS and QOS is not explicitly disabled on the local or
remote port, the link will come up in QOS mode.
Otherwise, the link will come up in normal mode.
If FOS v7.2 or later is factory installed (or net installed), Adaptive Networking features are always
available. This matches the behavior of the Brocade 6520 and all products shipping with prior
versions of FOS and with the Adaptive Networking license factory installed.
Ports will come up in AE mode by default
If the remote port supports QOS and is not explicitly disabled, the link will come up in QOS
mode. Otherwise, the link will come up in normal mode.
Access Gateway
Users who want to utilize Access Gateway’s Device-based mapping feature in the ESX environments
are encouraged to refer to the SAN TechNote GA-TN-276-00 for best implementation practices. Please
follow these instructions to access this technote:
Log in to http://my.brocade.com
Go to Documentation > Tech Notes.
Look for the Tech Note on Access Gateway Device-Based Mapping in VMware ESX Server.
Brocade HBA/Adapter Compatibility
Brocade HBA/Adapter should be using driver version 2.3.0.2 or later when attached to 16G ports on
Brocade switches.
D_Port
The 16Gb QSFP optics used in FC16-64 blade do not support electrical loopback and optical loopback
tests. Support is limited to:
o Link traffic tests across the 16Gb QSFPs
o Roundtrip link latency measurements
o Link distance measurements for links that are longer than 100 meter
Edge Hold Time
Edge Hold Time (EHT) default settings for FOS v7.x have changed from those in some FOS v6.4.x
releases. The following table shows the Default EHT value based on different FOS release levels
originally installed at the factory:
Factory Installed Version of FOS Default EHT Value
FOS v7.X 220 ms
FOS v6.4.3x 500 ms
FOS v6.4.2x 500 ms
FOS v6.4.1x 220 ms
![Page 42: v7.3.0_releasenotes_v2.0](https://reader036.vdocuments.us/reader036/viewer/2022082213/55cf94d1550346f57ba499d0/html5/thumbnails/42.jpg)
Fabric OS v7.3.0 Release Notes v2.0 Page 42 of 114
FOS v6.4.0x 500 ms
Any version prior to FOS v6.4.0 500 ms
Gen 5 platforms and blades are capable of setting an EHT value on an individual port basis. On 8G
platforms EHT is set on an ASIC-wide basis, meaning all ports on a common ASIC will have the same
EHT setting. Extra care should be given when configuring EHT on 8G platforms or Gen 5 platforms
with 8G blades to ensure E_Ports are configured with an appropriate Hold Time setting.
When using Virtual Fabrics and creating a new Logical Switch when running FOS v7.1.0 or later, the
default EHT setting for the new Logical Switch will be the FOS default value of 220ms. However, with
FOS v7.1.0 and later, each Logical Switch can be configured with a unique EHT setting that is
independent of other Logical Switches and the Default Switch. Any Gen 5 ports (Condor3 based)
assigned to that Logical Switch will be configured with that Logical Switch’s EHT setting. Any 8G ports
(Condor2 based) will continue to share the EHT value configured for the Default Switch.
For more information on EHT behaviors and recommendations, refer to the Brocade SAN Fabric
Resiliency Best Practices v2.0 document available on www.brocade.com.
Encryption Behavior for the Brocade Encryption Switch (BES) and FS8-18
SafeNet’s KeySecure hosting NetApp’s LKM (SSKM) is supported for data encryption operations with
SSKM operating in PVM mode. Please see SSKM documentation for operating in PVM mode for
details. Operation in HVM mode is not supported
RASlog SPC-3005 with error 34 may be seen if the link key used by a BES/FS8-18 is re-
established. Please refer to the LKM/SSKM Encryption Admin Guide for the workaround.
Also, please ensure that two (2) SSKM’s are present in the deployment for workaround to be
performed. For crypto tape operations, please ensure to use Emulex FC HBA firmware/drivers 2.82A4/7.2.50.007
or higher. Use of lower level firmware/drivers may result in hosts not being able to access their tape
LUNs through a crypto target container.
Adding of 3PAR Session/Enclosure LUNs to CTCs is now supported. Session/Enclosure LUNs (LUN
0xFE) used by 3PAR InServ arrays must be added to CryptoTarget (CTC) containers with LUN state set
to “cleartext”, encryption policy set to “cleartext”. BES/FS8-18 will not perform any explicit
enforcement of this requirement.
The Brocade Encryption switch and FS8-18 blade do not support QoS. When using encryption or
Frame Redirection, participating flows should not be included in QoS Zones.
The RSA DPM Appliance SW v3.2 is supported. The procedure for setting up the DPM Appliance with
BES or a DCX/DCX-4S/DCX 8510 with FS8-18 blades is located in the Encryption Admin Guide.
Support for registering a 2nd DPM Appliance on BES/FS8-18 is blocked. If the DPM Appliances are
clustered, then the virtual IP address hosted by a 3rd party IP load balancer for the DPM Cluster must
be registered on BES/FS8-18 in the primary slot for Key Vault IP.
With Windows and Veritas Volume Manager/Veritas Dynamic Multipathing, when LUN sizes less than
400MB are presented to BES for encryption, a host panic may occur and this configuration is not
supported in the FOS v6.3.1 or later release.
Hot Code Load from FOS v7.2.x to FOS v7.3 is supported. Cryptographic operations and I/O will be
disrupted but other layer 2 FC traffic will not be disrupted.
When disk and tape CTCs are hosted on the same encryption engine, re-keying cannot be done while
tape backup or restore operations are running. Re-keying operations must be scheduled at a time that
![Page 43: v7.3.0_releasenotes_v2.0](https://reader036.vdocuments.us/reader036/viewer/2022082213/55cf94d1550346f57ba499d0/html5/thumbnails/43.jpg)
Fabric OS v7.3.0 Release Notes v2.0 Page 43 of 114
does not conflict with normal tape I/O operations. The LUNs should not be configured with auto rekey
option when single EE has disk and tape CTCs.
Gatekeeper LUNs used by SYMAPI on the host for configuring SRDF/TF using in-band management
must be added to their containers with LUN state as “cleartext”, encryption policy as “cleartext” and
without “-newLUN” option.
FOS7.2 and later supports KMIP key vault type for Thales e-Security Key Authority SW v4.0.0 KMIP
servers. Please refer to the KMIP Encryption Admin Guide for more details.
Replication feature from Thales e-Security Key Authority KMIP server is not supported with
BES/FS8-18.
In FOS 7.1.0 or later the encryption FPGA has been upgraded to include parity protection of lookup
memory (ROM) within the AES engine. This change enhances parity error detection capability of the
FPGA.
BES/FS8-18 will reject the SCSI commands WRITE SAME, ATS(Compare and Write/Vendor Specific
opcode 0xF1) and EXTENDED COPY, which are related to VAAI (vStorage APIs for Array Integration)
hardware acceleration in vSphere 4.1/5.x. This will result in non-VAAI methods of data transfer for the
underlying arrays, and may affect the performance of VM related operations.
VMware VMFS5 uses ATS commands with arrays that support ATS. BES/FS8-18 does not support this
command set. Use of a workaround procedure is required in order to configure encryption in a VMFS
5 environment. Please refer to Brocade Tech Note “Deployment Options for VMware VMFS-5 with
Brocade Encryption” for details.
XIV storage arrays that have been upgraded to firmware 11.2x or later required to support encryption
on thin provisioned LUNs will report all XIV data LUNs as TP=Yes.
FCIP (Brocade 7800 and FX8-24)
Any firmware activation will disrupt I/O traffic on FCIP links.
Latency measurements supported on FCIP Tunnels:
o 1GbE & 10GbE - 200ms round trip time and 1% loss.
After inserting a 4G SFP in GE ports of an FX8-24 blade or 7800 switch, sometimes “sfpshow”
output might display “Cannot read serial data!”. Removing and re-inserting the SFP should
resolve this issue. It is recommended that users perform sfpshow immediately after inserting
the SFP and ensure SFP is seated properly before connecting the cables.
When running FOS v7.2.0 or later, if the new FCIP Circuit Group feature is configured on any
FCIP Circuits, a downgrade operation to pre-FOS v7.2.0 will be blocked until the feature is
removed from the FCIP configuration(s).
FCIP (Brocade 7840)
Brocade 7840 does not support FCIP connection to Brocade 7800 or FX8-24.
FOS v7.3.0 does not support non-disruptive firmware download in one-to-many sites
configuration.
FOS v7.3.0 does not support concurrent non-disruptive firmware download.
FOS v7.3.0 does not support non-disruptive firmware download on the 20VE Mode.
FOS v7.3.0 does not support 10G speed on the 24 16G FC ports on Brocade 7840.
FOS v7.3.0 does not support VEX port on Brocade 7840.
FOS v7.3.0 does not support base switch on Brocade 7840.
![Page 44: v7.3.0_releasenotes_v2.0](https://reader036.vdocuments.us/reader036/viewer/2022082213/55cf94d1550346f57ba499d0/html5/thumbnails/44.jpg)
Fabric OS v7.3.0 Release Notes v2.0 Page 44 of 114
FOS v7.3.0 does not support credit recovery on BI ports on Brocade 7840.
Running offline diagnostic tests results in FCIP tunnels down. Reboot the switch after offline
diagnostic tests to recover the tunnels.
FCoE/DCB/CEE (FCOE10-24)
When upgrading a DCX/DCX-4S with one or more FCOE10-24 blades from FOS v6.x to FOS v7.0.0 or
later, the user should carefully review Chapter 5 of the FOS v7.0.0 Converged Enhanced Ethernet
Administrator’s Guide.
Ethernet L2 traffic with xSTP Hello timer set to less than or equal to 3 seconds may experience
momentary traffic disruption during HA failover.
Hot plugging a CP with firmware level less than FOS v6.3.0 into a DCX or DCX-4S with an active
FCOE10-24 blade will result in the new standby CP not coming up.
When operating in Converged Mode, tagged traffic on the native VLAN of the switch interface is
processed normally. The host should be configured not to send VLAN tagged traffic on the switch’s
native VLAN.
When operating in Converged Mode, tagged frames coming with a VLAN tag equal to the configured
native VLAN are dropped.
The Converged Network Adapter (CNA) may lose connectivity to the FCOE10-24 if the CNA interface is
toggled repeatedly over time. This issue is related to the CNA and rebooting the CNA restores
connectivity.
The FCOE10-24 support only one CEE map on all interfaces connected to CNAs. Additionally, CEE map
is not recommended for use with non-FCoE traffic. QoS commands are recommended for interfaces
carrying non-FCoE traffic.
Before upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, if the CEE map “default” value
already exists, the same “default” value is preserved after upgrading to FOS
v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later. However, if the CEE map “default” is not configured before
upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, then after upgrading to FOS
v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the following CEE map “default” will be created
automatically:
cee-map default
priority-group-table 1 weight 40 pfc

When upgrading from FOS v6.3.x or v6.4.x to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the CEE
start up configuration dcf.conf file will be incompatible with the FCoE provisioning changes
implemented in v6.4.1_fcoe and later releases. Users can save the dcf.conf file as a backup and
apply it once the firmware upgrade is completed to get the DCX/DCX-4S to the same startup
configuration as in the older release.
It is recommended that Spanning Tree Protocol and its variants be disabled on CEE interfaces that are
connected to an FCoE device.
The Fabric Provided MAC Address (FPMA) and the Fibre Channel Identifier (FCID) assigned to a
VN_Port cannot be associated with any single front-end CEE port on which the FLOGI was received.
LLDP neighbor information may be released before the timer expires when DCBX is enabled on a CEE
interface. This occurs only when the CEE interface state changes from active to any other state.
When the DCBX is not enabled, the neighbor information is not released until the timer expires,
irrespective of the interface state.

The FCoE login group name should be unique in a fabric-wide FCoE login management configuration. If
there is a login group name conflict, the merge logic would rename the login group by including the
last three bytes of the switch WWN in the login group name. As long as the OUI of the switch WWNs
are identical this merge logic guarantees uniqueness in any modified login group name (switches with
the same OUI will have unique last 3 bytes in WWN). However, if the participating switches have
different OUIs but identical last three bytes in the switch WWNs, then the merge logic will fail to
guarantee uniqueness of login group names. This will result in one of the login groups being dropped
from the configuration. This means, no device can login to the login group that is dropped as a result
of this name conflict. Users must create a new login group with a non-conflicting name to allow device
logins.
Ethernet switch services must be explicitly enabled using the command “fosconfig –enable ethsw”
before powering on an FCOE10-24 blade. Failure to do so will cause the blade to be faulted (fault 9).
Users can enable ethsw after upgrading firmware without FC traffic interruption.
Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.4.1_fcoe1
to FOS v7.0 or later will be non-disruptive to FCoE traffic through FCOE10-24 blades and FC traffic.
Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.3.x, v6.4.x,
and v6.4.1_fcoe to FOS v7.0 or later will be disruptive to any traffic through the FCOE10-24 blades.
When rebooting a DCX or DCX-4S with an FCOE10-24 blade, Qlogic CNA and LSAN zoning, the switch
will become very unresponsive for a period of time. This is due to the CNA sending excessive MS
queries to the switch.
The FCOE10-24 can handle 169 small FCoE frames in bursts. If you are using the FCOE10-24, and
you delete a large number of v-ports with HCM, some of the v-ports may not appear to be deleted. To
correct this, disable and re-enable FCoE with the following CLI commands:
switch:admin>fcoe –disable slot/port
switch:admin>fcoe --enable slot/port
When a FCOE10-24 blade is powered off during configuration replay, the interface specific
configuration won’t get applied. Later when FCOE10-24 blade is powered on, all physical interfaces
will come up with default configurations. User can execute “copy startup-config running-config”
command to apply the new configuration after powering on the FCOE10-24 blade.
When IGMP Snooping is disabled on a VLAN, all configured IGMP groups are removed from that VLAN.
User has to reconfigure the IGMP groups after enabling the IGMP snooping on that VLAN.
FOS v7.3 adds the support of FCOE10-24 blade in DCX 8510-8 chassis with following limitations:
o Only one FCOE10-24 blade is supported at the fixed slot 1 position. Inserting the blade into
other slot positions, however, will not fault the blade.
o An FCOE10-24 blade can co-exist with FC16-32 and FC8-32E blades only in a DCX 8510-8
chassis.
o Only supports FCoE direct attach.
o Layer2 Ethernet traffic is not supported.
o If an FCoE10-24 blade is inserted into a DCX 8510-8 chassis, it is required to reboot the
chassis or slot poweroff/poweron core blades. A chassis reboot or slot poweroff/poweron
core blades must also be performed if the FCoE10-24 blade is removed and replaced with
another blade type.
FCR and Integrated Routing
With routing and dual backbone fabrics, the backbone fabric ID must be changed to keep the IDs
unique.
VEX edge to VEX edge device sharing will not be supported.

Forward Error Correction (FEC)
Though FEC capability is generally supported on Condor3 (16G capable FC) ports when operating at
either 10G or 16G speed, it is not supported with all DWDM links. Hence FEC may need to be disabled
on Condor3 ports when using DWDM links with some vendors by using portCfgFec command. Failure
to disable FEC on these DWDM links may result in link failure during port bring up. Refer to the
Brocade Fabric OS 7.x Compatibility Matrix for supported DWDM equipment and restrictions on FEC
use.
FICON
For FICON qualified releases, please refer to the Appendix: Additional Considerations for FICON
Environments section for details and notes on deployment in FICON environments. (This appendix is
only included for releases that have completed FICON qualification).
FL_Port (Loop) Support
FL_Port is not supported on FC16-32, FC16-48, FC16-64, FC8-32E, FC8-48E, Brocade 6510, Brocade
6505, Brocade 6520, or Brocade 7840.
The FC8-48 and FC8-64 blade support attachment of loop devices.
Virtual Fabrics must be enabled on the chassis and loop devices may only be attached to ports on
a 48-port or 64-port blade assigned to a non-Default Logical Switch operating with the default 10-
bit addressing mode (they may not be in the default Logical Switch).
A maximum of 144 ports may be used for connectivity to loop devices in a single Logical Switch within
a chassis in 10-bit dynamic area mode on DCX-4S.
A maximum of 112 ports may be used for connectivity to loop devices in a single Logical Switch within
a chassis in 10-bit dynamic area mode on DCX.
Loop devices continue to be supported when attached to ports on the FC8-16, FC8-32 with no new
restrictions.
Flow Vision
Users must not specify well known FC addresses, domain controller addresses or CUP Port ID (in FMS
mode) for either the source or the destination device field while defining flows.
Flow Vision does not support port swap. Users must not create flows on ports that are already
swapped and users must not swap the ports on which the flows are currently defined.
After a HA reboot, a flow generator flow can be created if the source or the destination port is F-Port.
But traffic will not be initiated. Toggling the port will enforce the restriction again to simulated ports.
Flow Monitor does not support flows with defined LUN parameters on ingress ports on 8G platforms.
ICLs on DCX/DCX-4S
If a DCX with an 8-link ICL license is connected to a DCX with a 16-link license, the DCX with the 16-
link license will report enc_out errors. The errors are harmless, but will continue to increment. These
errors will not be reported if a DCX with a 16-link license is connected to a DCX-4S with only 8-link ICL
ports.
If ICL ports are disabled on only one side of an ICL link, the enabled side may see enc_out errors.
Native Connectivity (M-EOS interoperability)
A switch running FOS v7.0 or later cannot form E-port connectivity with any M-EOS platform.
![Page 47: v7.3.0_releasenotes_v2.0](https://reader036.vdocuments.us/reader036/viewer/2022082213/55cf94d1550346f57ba499d0/html5/thumbnails/47.jpg)
Fabric OS v7.3.0 Release Notes v2.0 Page 47 of 114
Platform running FOS v7.1 or later does not support EX port configuration in Interopmode 2 or
Interopmode 3.
Device sharing between a switch running FOS v7.1 or later and McDATA fabrics is allowed via
Integrated Routing platforms using FOS v7.0.x (or earlier) firmware.
Port Initialization
Users may observe that a port is in “Port Throttled” state when an F_Port is being initialized. This is mostly an
informational message that is shown in switchshow output indicating systematic initialization of F_Ports.
However, a port may remain in “Port Throttled” state for an extended period of time and may never come
online if it fails to negotiate speed successfully with the neighboring port. Users are advised to check the speed
setting of the neighboring switch port to determine the cause of the speed negotiation failure.
Example Output:
74 9 10 36ed40 id N8 In_Sync FC Disabled (Port
Throttled)
Port Mirroring
Port Mirroring is not supported on the Brocade 7800.
Port Statistics
On 16G capable ports, the enc_in (number of encoding errors inside of frames) and enc_out (number
of encoding errors outside of frames) counters will not be updated when a port is operating at either
10G or 16G speed. This is due to the different encoding scheme used at 10G and 16G speeds when
compared to 8G/4G/2G speeds. Because of this, Fabric Watch alerts and Port Fencing based on ITW
(Invalid Transmission Word) thresholds will not function as these enc_in and enc_out counters will not
be incremented when operating at either 10G or 16G (ITW is computed based on enc_in and enc_out
counters). Also any CLI or GUI that displays enc_in and enc_out counters will show no incrementing of
these counters when a port is operating at either 10G or 16G.
Both enc_in and enc_out counters contain valid information when a Condor3-based port is operating
at speeds other than 10G and 16G.
Virtual Fabrics
When creating Logical Fabrics that include switches that are not Virtual Fabrics capable, it is possible
to have two Logical Switches with different FIDs in the same fabric connected via a VF incapable
switch. Extra caution should be used to verify the FIDs match for all switches in the same Logical
Fabric.
A switch with Virtual Fabrics enabled may not participate in a fabric that is using Password Database
distribution or Administrative Domains. The Virtual Fabrics feature must be disabled prior to deploying
in a fabric using these features.
ISL R_RDY mode is not supported in a base switch with FOS version 7.0 or higher.
WebTools
WebTools since FOS v7.1.0 has a “SupportSave” interface. It only collects, however, information
specifics to WebTools. It does not contain the same information as collected by supportSave initiated
through CLI or Brocade Network Advisor.
When launching WebTools on a computer without Internet access, it could take up to 5 minutes to
complete because the certificate revocation check performed for the WebTools application takes time
![Page 48: v7.3.0_releasenotes_v2.0](https://reader036.vdocuments.us/reader036/viewer/2022082213/55cf94d1550346f57ba499d0/html5/thumbnails/48.jpg)
Fabric OS v7.3.0 Release Notes v2.0 Page 48 of 114
to timeout. Users can turn off the certification revocation check on the Java control panel as a
workaround.
FOS v7.3.0 is qualified and supported with Oracle JRE 1.7.0 update 60. When launching Web tools
directly using the browser for FOS 7.3.0, ensure that Oracle JRE update 1.7u60 is installed in that
machine. WebTools can be launched from the local client of Brocade Network Advisor installed on
Windows OS. Launching WebTools from local client of Brocade Network Advisor installed on Linux OS
will fail due to the expiration check with JRE 1.7 update 51. As a workaround for this issue on Linux,
please do the following changes in the Brocade Network Advisor installed computer.
1. Add following lines in <User Home>/.java/deployment/deployment.properties file
deployment.expiration.check.enabled=false
For example, if the user is root then the absolute path of this file is as below
/root/.java/deployment/deployment.properties
2. Launch the java control panel using below command and click on Ok button
<Network Advisor Home>\jre\bin\jcontrol
Please refer to Brocade Network Advisor release notes for more details.
In addition, users must check the “Enable Java content in the browser” box under the Security tab of
Java Control Console to allow launching WebTools from BNA server clients.
Zoning
There are limitations to zoning operations that can be performed from a FOS v6.x switch that is in the
same fabric as a FOS v7.0 or later switch if the FOS v6.x switch is not running the recommended
firmware version. Please see Fabric OS Interoperability section for details.
Miscellaneous
Users must also keep the RADIUS accounting port (Authentication Port+1) open in the firewall
to ensure proper working of the RADIUS authentication.
Using a Windows anonymous FTP server for supportsave collection:
When using anonymous ftp, to avoid long delays or failure of simultaneous supportsave
collections when AP blades are present in a director chassis, the number of unlimited
anonymous users for a Windows FTP server should be configured as follows:
Number of anonymous FTP connections = (Number of director chassis) + (Number of
installed Application Blades x 3)
RASlog message AN-1010 may be seen occasionally indicating “Severe latency bottleneck
detected”. Even though it is a “Warning” message, it is likely to be a false alarm and can be
ignored.
POST diagnostics for the Brocade 5100 have been modified beginning with FOS v6.3.1b and
v6.4.0 to eliminate an “INIT NOT DONE” error at the end of an ASIC diagnostic port loopback
test. This modification addresses BL-1020 Initialization errors encountered during the POST
portloopbacktest. (Defect 263200)
It is important to note that the outputs of slotshow –p and chassisShow commands also
display the maximum allowed power consumption per slot. These are absolute maximum
values and should not be confused with the real-time power consumption on 16G blades. The
![Page 49: v7.3.0_releasenotes_v2.0](https://reader036.vdocuments.us/reader036/viewer/2022082213/55cf94d1550346f57ba499d0/html5/thumbnails/49.jpg)

chassisshow command has a “Power Usage (Watts):” field that shows the actual power
consumed in real-time on 16G blades.
Class 3 frames that have been trapped to CPU will be discarded in the following scenarios on
DCX/DCX-4S/DCX 8510 during the following conditions:
HA failover on DCX/DCX-4S/DCX 8510 platforms while running FOS v7.0 or later firmware
Firmware upgrade from v7.0 to a later release on Brocade 300, 5100, VA-40FC, 5300,
6510
Firmware upgrade from v7.0.1 to a later release on Brocade 6505
Firmware upgrade from v7.1.0 to a later release on Brocade 6520
The QSFP information in the sfpshow output will indicate the ID field as all zeros. This is as
designed.
ras080:FID128:root> sfpshow 5/32
QSFP No: 8 Channel No:0
Identifier: 13 QSFP+
Connector: 12 MPO Parallel Optic
Transceiver: 0000000000000000 16_Gbps id
It is recommended that for directors with more than 300 E_Ports, the switch be disabled prior
to executing the “switchCfgTrunk” command (used to disable or enable trunking on the
switch).
During non-disruptive firmware upgrades, E_Ports in R-RDY mode may cause some frame
drops on the E-port links.
The Brocade Network Advisor seed switch should always have the highest FOS version used in
the fabric.
For login authentication through RADIUS, Brocade switch should be able to reach RADIUS
servers through TCP authentication port (default 1812) and accounting port (default 1813).
Both of these ports must be kept open in any firewall settings.
When a firmware upgrade on a Brocade 6510 switch initiated through Brocade Network
Advisor results with “failed to enforce new iptable rules” error message, the switch could be
inaccessible via SSH and/or Telnet. Activating (from console) a new policy with rules of
default active policy will restore access to the switch.
Firmware downgrade from FOS v7.3.0 with one or more ports enabled with the Flow
Generator feature as a SIM port will be blocked. The SIM ports configuration must first be
disabled.
Firmware upgrade to FOS v7.3.0 with one or more ports enabled with the Flow Generator
feature as a SIM port will be blocked. The SIM ports configuration must first be disabled.
FOS v7.3.0 includes a fix for defect 492340 where users may see frame drops on the back-
end edge and core ports with FS8-18 and FX8-24 blades in DCX 8510 chassis. This fix will
only take effect after the affected blades are powered off and on. After the fix takes effect, a
new credit allocation model leads to fewer credits available for long distance ports. If there
are long distance port configurations that have used up all the credits prior to applying this fix,
some long distance ports may experience degraded performance.

the reports or CLIs that show routing data for those specific domains. (Examples include
topologyShow, uRouteShow, director diagnostics for FICON, and others.)
When the problem corrects itself , the customer's traffic may experience re-routes as the switch adjust
routes to start using the previously missing paths. The correction of the problem to include the
missing paths happens automatically within a time window of 30 minutes from when the problem

occurs, out of order frames are always a possibility for mutli-hop routes. In this case, since the
reroutes happen at a later time than a cust
Condition: The switches must have Lossless DLS enabled. Then, the problem can happen when parallel paths to
an existing domain are added due to a new domain joining the fabric. For example: a diamond
topology where one of the points of diamond is offline and being brought back online.
Workaround: The switches will automatically correct the problem within 30 minutes.
If the customer wants to control when the reroute happens, they could bounce one of the missing
ISLs and this will cause FSPF to correct the problem. (Note: if the ISL is a trunk, all members of
the trunk must be bounced to generate the necessary events.)
Adding a new ISL that does not join an existing trunk group will also generates the necessary
events to fix the problem.

Symptom: Name Server (NS) queue full condition leads to NS out of sync with local/remote devices and the
device connectivity info will become inconsistent.
Condition: When a new switch, which is in AllAccess mode and has local attached deviced, joins a large fabric
consisting of a large number of devices (> 1000) and a large zone configuration (around 1MB)
enabled, there is a possibility that the customer may see NS queue full condition. This happens due to
Name Server discovery occurring before the existing fabric's zone configuration getting merged
across to the new switch.
Workaround: There are a couple workarounds for such a scenario and they are part of best-practices strategy for
large fabrics.
1. When connecting a new switch to a fabric, put it in NoAccess mode. This will avoid the
momentary transition to AllAccess and resultant RSCN storm to the fabric.
2. If connecting a new switch in AllAccess mode, take all devices connected to that switch offline
to prevent RSCN storm.
Recovery: Reboot the switch to recover from the error condition.

Defect ID: DEFECT000513920
Technical Severity: High Probability: Low
Product: FOS Technology: Security
Reported In Release: FOS7.1.0 Technology Area: Fabric Authentication
Symptom: CVE-2014-0224: OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not
properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers
to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and
consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the
"CCS Injection" vulnerability.
Condition: FOS switches that are not running LDAP or RADIUS with PEAP-MSCHAPv2 for authentication are
not running OpenSSL client mode and are not at risk. To be at risk:
• The FOS product must be running authentication using LDAP or RADIUS with PEAP-MSCHAPv2
protocols.
• The OpenSSL server must also be running with a version of OpenSSL that contains this vulnerability
(1.0.1 or 1.0.2-beta1)
Workaround: For users requiring LDAP or RADIUS with PEAP-MSCHAPv2 for authentication, upgrading the
OpenSSL server to a version of OpenSSL that does not contain this vulnerability will prevent
exposure.
