Bi-directional GBIC (MGBIC)

The Bi-directional Gigabit Interface Converters are deployed as a pair. One of the SFP Mini-GBICs is placed at one end of a single strand of sin-gle mode fiber (terminated with an LC UPC1 connector) and the second at the other end of the same fiber, achieving bi-directional transmission on a single fiber. These Mini-GBICs support the Digital Optical Monitoring (DOM) extensions to the SFP standard.

BPP Beacon Priority Policy - A role/service that allows for the Beacon packet to have the highest priority when propagating though the network. This ensures the Beacon packet will be transmitted back to the PBQ in a flooded switch.

Circuit Breaker PBQ/SBQ (CBPBQ/CBSBQ)

This is used to refer to policy rule that will disable an uplink (ISL) port that interfaces two root switches that receives an incoming packet of an outgoing Beacon packet “Loop”. This function is a subset of the Circuit Breaker.

CLI Command Line Interface

Core Switch Refers to the main body of switches that provide the network with its backbone connections. A core switch can also be considered an “edge switch” in reference to the root; however the outer most edge switches within the network are normally not considered to be core switches.

CoS Class of Service is based on the IEEE 802.1D (802.1p) standard specifica-tion, and allows you to define eight priorities (0-7, with 7 granted highest priority). CoS allows you to assign data to higher priority through the device by delaying less critical traffic during periods of congestion. The higher priority traffic through the device is serviced first before lower pri-ority traffic. The Class of Service capability of the device is implemented by a priority queueing mechanism.

Redundant Power Supply CapabilityThe A4-series (P0973JM/P0973JN/P0973JP) switches have the capability to support power sup-ply redundancy when connected to an optional external Redundant Power Supply Module (RPSM) (P0973BP). If the internal power supply fails, the RPSM assumes the entire load of the switch without interrupting network traffic. The switch's internal power supply and RPSM each have their own ac power connection, which enables the connection of each power supply to a dif-ferent ac power circuit for additional ac power source redundancy.

The A4-series switches’ additional access plates as shown in Figure 1-4 are non-functional and cannot support redundant internal power supplies. Adding an additional internal power supply disrupts the internal thermal characteristics, and decreases the overall thermal specification (0 to +50°C (32°F to 122°F)) of the switch. This capability cannot be supported on the A4-series switch.

Figure 1-4. Redundant Power Access Plates on Rear of A4-Series Switches

A4-series Ethernet Managed Switch Visual IndicatorsIndicators on the front of the switch indicate: CPU, RPS, and MGR. The CPU indicator, indi-cates the health of the control processor. The RPS indicates the status of the redundant power supply. The MGR indicator, when lit indicates the switch is in Managed mode, when off indi-cates the unit is a member of a stack (See Caution below). Indicators for each port and uplink (ISL) indicate: port enabled and link activity, data collisions and diagnostic failure. Refer to “LANVIEW® Diagnostic LEDs” on page 26 for a full description of these LEDs.

CAUTION!A4-series stacking ports must be configured as uplink (ISL) ports prior to connect-ing them to other switches. If an A4-series switch’s stacking port is connected prior to their configuration the switch will boot-up in a stacking mode, which is not allowed in The MESH control network due to sub-second failover requirements.

A4-series Ethernet Managed Switch Mini-GBIC Modules

NOTEOn an A4-series switch, the two stacking ports (see “Port 25/Up and 26/Down” in Figure 1-5) must be configured as standard Gigabit Ethernet ports. [Refer to “Switch Configuration” on page 36, step 5.]

Figure 1-5. Stacking Ports on an A4-series Switch

The two stacking/uplink (ISL) ports accept a RJ-45 Category 5 copper cable (1000Base-T). Dual ports allow both upstream and downstream switches to be connected using the high speed Giga-bit Ethernet protocol over CAT5 copper cable when configured as an uplink (ISL) port.

The two 1000Base-X uplink (ISL) Gigabit (SFP) ports can be populated with Mini-GBIC mod-ules as shown in Figure 1-6. Dual ports allow both upstream and downstream switches to be con-nected using the high speed Gigabit Ethernet protocol over CAT5 copper cable or Fiber Optic cables utilizing a variety of Mini-GBIC modules for connectivity. Refer to Table 1-1.

Figure 1-6. Fiber Uplink (ISL) Mini-GBIC Module’s with LC Connector (P0972WT, P0972WU, P0972YQ and P0973FT)

The 1000Base-BX Fiber uplink (ISL) Mini-GBIC modules with Simplex LC connectors (P0973JB and P0973JC) are shown in Figure 1-7. 1000Base-BX is a version of Fast Ethernet over a single strand of optical fiber (unlike 1000Base-LX, which uses a pair of fibers). Simplex single-mode fiber is used, along with a special multiplexer (Mini-GBIC) which splits the signal into transmit and receive wavelengths. The two wavelengths used for transmit and receive are either 1310 nm or 1490 nm. The Mini-GBIC modules on each side of the fiber are not the same device, as the one transmitting P0973JC Mini-GBIC module “downstream” (from the core of the net-work to the edge) uses the 1490 nm wavelength, and the “edge” transmitting P0973JB Mini-GBIC module “upstream” uses the 1310 nm wavelength with a distances up to 10 km (6.2 mi).

Redundant Power Supply System Chassis (RPSC) Overview (P0973BM/BN)The Redundant Power Supply Chassis (RPSC) provides a simple and economical solution for providing a backup power source for up to eight Ethernet switch devices. When a Redundant Power Supply Module (RPSM) (P0973BP) is connected to a switch, the RPSM continuously monitors the internal power supply of the switch. If a power interruption is detected, the RPSM is automatically triggered to provide power for the switch, preventing an interruption in network traffic.

The end result is a more reliable network infrastructure, protecting the network from a single source of failure from a network device power supply.

Depending on your system requirements, the RPSC can consist of the following components to support up to eight switch devices:

♦ One RPSC chassis (P0973BM)

♦ Up to eight RPSMs (P0973BP)

♦ Up to eight ac power cords (one cord per RPSM)

♦ Up to eight PSM cables (one per RPSM)

NOTEThe chassis is shipped with one RPSM (P0973BP). Additional RPSMs are ordered separately. Each RPSM is shipped with an interconnecting PSM cable and an ac power cord.

Figure 1-8. A4-series Ethernet Managed Switch Redundant Power Supply Module (P0973BP)

The 156 watt Redundant Power Supply Module (P0973BP) can supply redundant power for the 24-port Copper (P0973JM), 24-port Fiber (P0973JN), and or the 8-port Copper / 8-port Fiber (P0973JP) managed switches.

For mounting purposes only, the RPSM (P0973BP) must be used with the RPSC (P0973BM/BN). These chassis do not have ac power connections or electronics.

The RPSM (P0973BP) provides the following:

♦ Hot swap capability

♦ One 12 V dc, 150 Watts of maximum - continuous power output to a connected SecureStack device.

♦ Front panel status LED that indicates if the RPSM is operating correctly.

The P0973BN power supply chassis accommodates 2 RPSs (P0973BP) which can support up to two A4-series and/or C-series switches. The P0973BM power supply chassis accommodates up to eight RPSs (P0973BP) which can support up to eight A4-series and/or C-series switches.

Both units are desktop, shelf, or 19-inch rack mounting.

The specifications for the redundant power supply are provided in Table 1-2:

Media ConverterThe media converter provides a way to connect devices that use 100 Mbit CAT5-STP copper cable (RJ-45 connectors) to a device that uses 100FX multimode fiber optic cable. The media converter allows connection between copper and fiber devices. A media converter allows you to connect a workstation or a controller to an Ethernet switch that is not equipped with fiber optic ports, while gaining the benefits of extended range isolated fiber optic transmission.

Refer to Media Converter Installation and Configuration Guide for Control Networks (B0700CP) for all information on the media converter types available for use with these switches.

2. Site Planning
This chapter describes the steps that should be taken and the options that should be considered when planning the inclusion of the A4-series Ethernet managed switches in The MESH control network and I/A Series control network.

The design of each MESH control network or I/A Series control network is different, and depends on the needs and requirements of the individual site. The following paragraphs provide the information necessary to help network designers to plan the control network that meets the needs of their specific site.

Refer to The MESH Control Network Architecture Guide (B0700AZ) or the Control Network User’s Guide (B0400DV) for details about overall site planning.

A4-Series Ethernet Managed Switch Features and Capabilities

The following sections describe the features and capabilities of the A4-series Ethernet managed switches that are offered by Invensys for use in The MESH control network and the I/A Series control network. Use this information to aid in the selection of equipment to implement the net-work design plan.

For installation, you can mount these switches on a flat table, shelf surface, or a grounded 48.3 cm (19 in wide) equipment rack. Install the switch in a dry area with adequate air circula-tion. Avoid placing the switch in direct sunlight or near other heat sources, such as hot-air vents.

NOTEDo not restrict airflow by covering or obstructing air inlets or internal air fan exits on any side of the switch.

24-Port Copper SwitchThe 24-Port Copper switch (P0973JM) (refer to “24-Port Copper Managed Switch (P0973JM)” on page 2) provides twenty-four 10Base-T/100Base-TX RJ-45 ports. The switch automatically selects the operational speed of its RJ-45 ports, and negotiates the connection with the attached device. It has auto MDI/MDI-X selection.

This switch is equipped with two fixed 10/100/1000Base-T stacking / uplink (ISL) ports with RJ-45 connectors and two 1000Base-X uplink (ISL) Gigabit (SFP) ports. The two 1000Base-X uplink (ISL) Gigabit (SFP) ports can be populated with Mini-GBIC uplink (ISL) connector modules (P0972WT, P0972WU, P0972YQ, P0972YL, P0973JD, or P0973FT). Refer to Table 1-1 on page 8 for details on the connector modules.

2. Site Planning B0700CF – Rev A

Redundant Power Supply Chassis (RPSC) Guidelines (P0973BM/BN)The following guidelines must be observed when a site is selected for the Redundant Power Sup-ply Chassis (P0973BM/BN). If the guidelines are not followed, unsatisfactory network perfor-mance may result.

The installation site must be within reach of the network cabling and meet the requirements listed below:

♦ Chassis placement close enough to connect the 2 m (6.6 ft) PSM cables from the RPSMs to the ac power source.

♦ Up to eight three-pronged power receptacles capable of delivering the current and voltage specified below. Up to eight ac outlets on independently fused circuits must be within 1.82 m (6 ft) from the installation site. If there is an ac power source failure, this will prevent the powering down of RPSMs due to a single source power failure.

3. Installation
This chapter describes the steps necessary to install the A4-series Ethernet managed switches as part of The MESH control network and the I/A Series control network.

Installation of the Ethernet switches in their appropriate control network consists of locating the individual components and then making connections between them using fiber optic or copper cable.

Installing A4-Series Ethernet Managed SwitchesThe A4-series Ethernet switches are designed to be placed on a flat, level surface. Alternatively, the switches may be mounted in a rack using the supplied mounting brackets. Make sure that the environment in which the switch is located meets the switch’s environmental operating specifica-tions, especially heat and humidity. Refer to the documentation included with the switch for detailed installation instructions and operating specifications.

Installing Optional Mini-GBIC ModulesOptional Mini-GBIC modules are available for all three of the A4-series Ethernet managed switches. They should be installed before the switch is connected to its appropriate control net-work.

Refer to the documentation included with the uplink (ISL) modules and the switch for instruc-tions on installing the modules.

CAUTION!If a Mini-GBIC module is to be added or removed from the switch hardware con-figuration, a complete software reconfiguration of the switch is necessary after it is installed or removed.

Installing Optional Redundant Power SuppliesOptional redundant power supplies are available for all three of the A4-series Ethernet managed switches. Redundant power supplies should be installed before the switch is connected to its appropriate control network.

Refer to the documentation included with the switch for instructions on installing redundant power supplies.

Configuring the SwitchesAll managed switches require configuration before they are added to their appropriate control network. The dual stacking ports must be reconfigured as uplink (ISL) ports for the first-time installation or re-initialization of a switch.

4. Switch Configuration
This chapter describes the steps necessary to configure the A4-series Ethernet managed switches as part of The MESH control network and the I/A Series control network.

Configuring Ethernet SwitchesThere are two methods available to configure A4-series Ethernet managed switches:

♦ The MESH Network Switch Configurator Application Software, and

♦ Command Line Interface (CLI).

The MESH Network Switch Configurator Application Software (SCAS)The MESH Network Switch Configurator Application Software (SCAS) for the I/A Series system control network was created for Invensys customers as a configuration tool for qualified Ethernet switches. It reduces the repetitive Command Line Interface (CLI) command entries which are required to configure The MESH control network switches, by allowing users to customize con-figuration files that define a set of CLI commands downloadable via the serial port. SCAS is designed and tested for operation with the A4-series Ethernet managed switches and their uplink (ISL) modules.

Refer to The MESH Control Network Operation, and Switch Installation and Configuration Guide (B0700CA) document for information on how to use SCAS.

CAUTION!The A4-series switch should be configured using SCAS, revision 3.4.1 or greater. This revision can be found at the Global Customer Support Center web site, listed below.

The latest version of the tool and its documentation are available on the Global Customer Sup-port Center web site

http://support.ips.invensys.com

After logging in to the web page, go to: Support -> Foxboro -> Product Information -> Briefs/Product Releases -> then select MESH Network Switches Documentation

Details on downloading SCAS are provided in The MESH Control Network Operation, and Switch Installation and Configuration Guide (B0700CA) document, in the section “Getting the Latest Configuration Revision”.

Customers are encouraged to download and use the latest documentation and configurator tools on the Global Customer Support Center web site.

Command Line Interface (CLI) EntriesThis section provides instructions and specific CLI entries that must be typed and entered into the switches for proper operation in their appropriate control network.

B0700CF – Rev A 4. Switch Configuration

Logging InBy default, the A4-series switch is configured with three user login accounts:

♦ ro for Read-Only access

♦ rw for Read-Write access

♦ admin for superuser access to all modifiable parameters.

The default password is set to a blank string. For information on changing these default settings, refer to The MESH Control Network Operation, and Switch Installation and Configuration Guide (B0700CA, Rev. H or later) document, in the section “Changing Switch Password and Settings.”

Configuration RequirementsAll managed switches require configuration before they are added to their appropriate control network.

CAUTION!Switches should be configured off line before they are connected to The MESH control network.The A4-series Ethernet managed switches have their two fixed RJ-45 stack-ing/uplink (ISL) ports configured in stacking mode when shipped. You must con-figure them in uplink (ISL) mode before connecting any uplink cables to them.

Configuration of managed switches is accomplished by connecting a terminal (or a computer run-ning terminal emulation software) to the serial console port on the switch and using the switch’s resident management software to set the parameters. Refer to “Connecting Ethernet Switch to the PC” on page 33. For customized switch configurations, refer to the documentation included with the switch for command line entry instructions on configuring a specific switch model.

To avoid the possibility of address conflicts, IP addresses for managed switches are automatically assigned by the system configurator (SysDef or IACC). Once the configurator has selected the IP addresses, each switch must be configured with its IP address (refer to “The MESH Control Net-work Addresses” in The MESH Control Network Architecture Guide (B0700AZ), or the Note on selecting an IP address on page 45 for an I/A Series control network, as appropriate).

For information on using the system configurator, refer to:

♦ I/A Series System Definition: A Step-by-Step Procedure (B0193WQ) or

♦ I/A Series Configuration Component (IACC) User’s Guide (B0400BP).

While using SysDef, record the address of the station monitoring the switch. There is a switch parameter named TRAP under the SNMP Configuration menu that you should set based on this IP address.

CAUTION!Do not mirror active ports to other used ports. Doing so results in an excessive increase in the traffic levels routed by the switches.

4. Switch Configuration B0700CF – Rev A

NOTEWhen adding a switch or blade to the network, clear the NVRAM, or return the switch to the Factory Default Configuration to obtain default settings before con-figuring the switch.

NOTEUplink (ISL) ports should be installed and configured first. Otherwise, configured information may be lost when the uplink ports are installed.

This chapter provides generic configuration information that applies to all Ethernet switches and specific procedures for the switches that have been tested and qualified by Invensys for use with I/A Series systems. The configuration information is presented as follows:

♦ “Generic Switch Parameters” on page 34

♦ “Connecting Ethernet Switch to the PC” on page 33

♦ “Switch Configuration” on page 36

Connecting Ethernet Switch to the PCThe Network Administrator computer (laptop recommended) needs to be connected to the switch’s CLI port (for example, serial port) through the computer’s COM port using cable P0973EY.

Figure 4-2 shows the connection from a PC to the Ethernet switches.

The A4-series switches use P0973EY, a 9-pin D connector on their CLI port to connect to the9-pin D connector on the PC (see Table 4-1).

Edge SwitchesAn edge switch is a switch which will not be configured as a root or backup bridge. The edge switch usually interfaces I/A Series system devices (Control Processors, FCMs, and so forth) to the root switches. Multiple root switches can be configured to take over as roots by adjusting the Bridge Priority Value. However, normally only two roots exist, primary and backup root switch, all other switches are defined as edge switches.

Auto-negotiation mode with no flow control, Fiber ports

For fiber ports, set to 100 Base Full Duplex mode with no flow control.

Flow control Disable full and half-duplex flow control (IEEE 802.3x) on all the switch ports

Rapid Spanning Tree Protocol (RSTP)

Enable RSTP (IEEE 802.1w). It may be enabled by default on some switches.

Switch Priority For primary root and backup root switches (as defined by network architecture), set the switch priority to 28672 for the root and 28673 for the backup root. All other edge switches (does not apply to the P0973BL), set switch prior-ity to 32768.

Port Mirroring Disabled, by default, unless you intend to execute specific diagnostics

Spanning Tree Edge Port For all 100 Mb “end device” ports (FCP, ZCP, worksta-tions, ATS and FCM100 devices), AdminEdge set to True (Enabled); for all 1 Gb/100 Mb uplink (ISL) ports, AdminEdge set to False (Disabled).

Uplink Port Auto-negotiation For all 1 Gb/100 Mb uplink (ISL) ports, set Auto-negotia-tion to Enabled.

SNMP Trap Set the SNMP trap to the primary and alternate port addresses (151.128.152.XXX and 151.128.24.XXX) of the workstation (System Monitor Host) that is monitoring the switch.

Trap Subnet Mask Set the subnet mask for the traps to 255.255.0.0.

Broadcast Rate Limit 500 packets per second for 100 Mb ports and 5000 packets per second for 1 Gb ports.

NOTEThe concept of root and edge switches is not applicable to the I/A Series control network.

Switch ConfigurationConfiguration for The MESH control network differs for the:

♦ 24-Port Copper / Fiber switches (P0973JM/P0973JN)

♦ 8x8 switch (P0973JP)

NOTETo configure the A4-series switches for I/A Series software, Version 7.x as part of the I/A Series control network, refer to Appendix B “Configuring A4-Series Switches for I/A Series Software Version 7.x” on page 43.

The A4-series switches (P0973JM, P0973JN, P0973JP) must be booted with a supported version of I/A Series qualified and compatible firmware. (Refer to the Appendix “Qualified Switch Firm-ware Compatibilities Matrix” in The MESH Control Network Operation, and Switch Installation and Configuration Guide (B0700CA) for supported versions.)

To configure these switches, it is recommended that you refer to The MESH Control Network Operation, and Switch Installation and Configuration Guide (B0700CA) and use the latest Switch Configurator Application Software to configure this switch.

Resetting PasswordThe switch’s Command Line Interface (CLI) locks out after three incorrect password attempts and remains locked out for 15 minutes. The Reset Password switch remains non-functional for those 15 minutes.

NOTEPower must be applied to the unit before the 15 minute lockout can expire.

If you forget the switch’s login password, use the Reset Password switch as described in the fol-lowing procedure.

36


Figure 4-3. A4-Series Reset Password Switch

To reset the A4-series switch password, refer to Figure 4-3 and proceed as follows:

1. Press and hold the Reset Password switch while the switch is operational. This change of the login password to the default password will be indicated via CLI only.

2. Login to the device management (see “Logging In” on page 32). Now, you can login to the switch via the console port and assign a new password. For information on changing the password settings, refer to The MESH Control Network Operation, and Switch Installation and Configuration Guide (B0700CA, Rev. H or later) document, in the section “Changing Switch Password and Settings.”

MaintenanceFor all maintenance information, refer to The MESH Control Network Architecture Guide (B0700AZ) or the Control Network User’s Guide (B0400DV).

Appendix B. Configuring A4-Series Switches for I/A Series Software Version 7.x
This appendix discusses the manner for configuring A4-series switches for use in an I/A Series control network connected to workstations running I/A Series software, Version 7.x.

For more information on the I/A Series control network, refer to Control Network User’s Guide (B0400DV).

The A4-series switches (P0973JM, P0973JN, P0973JP) must be booted with a supported version of I/A Series qualified and compatible firmware. (Refer to the Appendix “Qualified Switch Firm-ware Compatibilities Matrix” in The MESH Control Network Operation, and Switch Installation and Configuration Guide (B0700CA) for supported versions.)

To configure these switches, it is recommended that you refer to The MESH Control Network Operation, and Switch Installation and Configuration Guide (B0700CA) and use the latest Switch Configurator Application Software to configure this switch.

Software Configuration for I/A Series Software Version 7.x

To configure A4-series switches (P0973JN, P0973JM, and P0973JP) for use with workstations running I/A Series software, Version 7.x, proceed as follows:

1. Connect the workstation to the switch.

a. Connect the console cable to the serial port on a workstation (COM1 or COM2).

b. Connect the other end of the cable to the COM port on the switch.

c. On an XP/NT/2000 workstation: click Start -> Programs -> Accessories -> Communications -> HyperTerminal.

d. In the name box, type: INVENSYS SWITCHES. Click OK.

e. Select the appropriate serial port to which the switch is connected (COM1 or COM2).

f. The COM1/COM2 properties dialog opens, the settings should be:

♦ Bits Per Second: 9600

♦ Data Bits: 8

♦ Parity: None

♦ Stop Bits: 1

g. Click OK.

B0700CF – Rev A Appendix B. Configuring A4-Series Switches for I/A Series

NOTEWhen using HyperTerminal® software with the Microsoft Windows 2000® oper-ating system, ensure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 fixes the problem of arrow keys not functioning in HyperTerminal's VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs.

2. Log-in to the switch with a default user account.

a. When asked for your user name, type: admin. Press <Enter>.

b. When asked for your password, press <Enter>.

3. To provide better security to the switch, change the password and login functions:

NOTEThe password must be at least 8 characters long. In the following steps, ******** is the user defined password for this switch. Passwords are not displayed on the con-sole screen.

♦ A4 (su)-> set password admin

♦ Please enter new password: ********

♦ Please re-enter new password: ********♦ Password changed.

♦ A4 (su)-> set system login ro read-only disable

♦ A4 (su)-> set system login rw read-write disable

4. To clear the switch configuration:

NOTEThe following command should be performed before configuring the switch to ensure the switch is in a known state. This command resets the switch.

♦ A4 (su)-> clear config

5. At this point, the stacking ports must be configured as uplink (ISL) ports.

NOTEThe following command resets the switch.

♦ A4 (su)-> set switch stack-port ethernet

♦ A4 (su)-> Y

44

Appendix B. Configuring A4-Series Switches for I/A Series Software Version 7.x B0700CF – Rev A

NOTEWhen an A4-series switch has the front panel uplink (ISL) ports configured in Ethernet mode, clear config will not change the uplink (ISL) ports to stacking mode. The clear config all command will set the uplink (ISL) ports to stacking mode.

6. Once the switch has booted, set up the IP address of the switch. Enter the IP address (151.128.79.nnn) that was assigned to the switch defined by the SysDef or IACC during the I/A Series system configuration.

NOTEWhen selecting the IP address, in order to avoid the possibility of address conflicts, IP addresses for managed switches should be assigned sequentially beginning with address 151.128.79.1 and continuing through 151.128.79.192.For example, the first configured switch should be assigned an address of 151.128.79.1, the second configured switch should be 151.128.79.2, and so forth. In the event that more than 192 addresses are needed, the block of addresses from 151.128.80.1 through 151.128.80.192 can be used for additional switches.

♦ A4 (su)-> set ip address 151.128.79.nnn mask 255.255.0.0

7. Set the switch’s ID. The name you assigned to the switch (for example, letterbug) dur-ing system configuration should be assigned to the switch (for example, SW0001).

♦ A4 (su)-> set system name “SW0001”

♦ A4 (su)-> set system location “Bldg N32-049”

♦ A4 (su)-> set system contact “Joe Smith ext. 555”

NOTEIf an uplink (ISL) GBIC port is added or removed from the switch hardware config-uration, the following steps (8-13) must be entered to ensure proper operation.

8. Set up port configuration, as follows.

For fiber and copper switches (P0973JN, P0973JM, and P0973JP):♦ A4 (su)-> set flowcontrol disable

♦ A4 (su)-> set port lacp port *.*.* disable

♦ A4 (su)-> set port negotiation ge.1.* enable

♦ A4 (su)-> set mac agetime 65000

In addition, for the copper switch (P0973JM):♦ A4 (su)-> set port negotiation fe.1.* disable

♦ A4 (su)-> set port duplex fe.*.* full

♦ A4 (su)-> set port speed fe.1.* 100

In addition, for the copper switch (P0973JP):♦ A4 (su)-> set port negotiation

fe.1.1;fe.1.3;fe.1.5;fe.1.7;fe.1.9;fe.1.11;fe.1.13;fe.1.15disable

45


♦ A4 (su)-> set port duplex fe.1.1;fe.1.3;fe.1.5;fe.1.7;fe.1.9;fe.1.11;fe.1.13;fe.1.15 full

♦ A4 (su)-> set port speed fe.1.1;fe.1.3;fe.1.5;fe.1.7;fe.1.9;fe.1.11;fe.1.13;fe.1.15 100

NOTEWhen specifying a list of ports as shown above, there should be no blank spaces between the port numbers.

9. Set up the Spanning Tree Protocol, as follows.♦ A4 (su)-> set spantree version rstp

♦ A4 (su)-> set spantree adminedge fe.1.* true

♦ A4 (su)-> set spantree adminedge ge.1.* false

If the Fast Ethernet port is to be used as an uplink (ISL) port, disable the port admin-edge.

♦ A4 (su)-> set spantree adminedge fe.1.# false

# denotes the port to be used as an uplink (ISL) port.

Example 1:The following example disables adminedge on ports 1 through 4.

♦ A4 (su)-> set spantree adminedge fe.1.1-4 false

Example 2:The following example disables adminedge on ports 2 and 4.

♦ A4 (su)-> set spantree adminedge fe.1.2;fe.1.4 false

10. Configure security for the switch.♦ A4 (su)-> set gvrp disable

♦ A4 (su)-> set gvrp disable *.*.*

♦ A4 (su)-> set cdp state disable

♦ A4 (su)-> set cdp state disable *.*.*

♦ A4 (su)-> set SSH disable

♦ A4 (su)-> set telnet disable all

♦ A4 (su)-> set webview disable

CAUTION!Leaving unused Ethernet ports enabled is a high security risk. It is recommended that all unused Ethernet and uplink (ISL) ports be disabled.

11. Disable unused ports as recommended above.♦ A4 (su)-> set port disable fe.1.#

# denotes port to be disabled

Example 1:The following example disables port 12.

♦ A4 (su)-> set port disable fe.1.12

46

Appendix B. Configuring A4-Series Switches for I/A Series Software Version 7.x B0700CF – Rev A

Example 2:The following example re-enables port 12.

♦ A4 (su)-> set port enable fe.1.12

12. Save the current configuration file in the Invensys-startup file.♦ A4 (su)-> show config outfile configs/Invensys.cfg

♦ A4 (su)-> save config

Switch setup is complete.
