NOTE
The SNMP NBI supports two formats of management information bases (MIBs): U2000 MIB and U2000-T
MIB.
l Both HW-IMAPV1NORTHBOUND-TRAP-MIB.mib and HW-IMAPV2NORTHBOUND-TRAP-
MIB.mib refer to the U2000 MIB, which is used to manage transport, access, and datacom devices, or cross-domain devices. V1 and V2 indicate the SMI (Structure of Management Information) versions of the HW-
IMAPV1NORTHBOUND-TRAP-MIB.mib and HW-IMAPV2NORTHBOUND-TRAP-MIB.mib
respectively. The OSS selects a version based on its supported SMI version. SMI versions differ in syntax.
For details, see RFC 1155 and RFC 1902.
l T2000-NETMANAGEMENT-MIB.mib refers to the U2000-T MIB, which supports upgrades of original
transport NMSs and can manage only transport devices.

2 Overview
About This Chapter
iManager U2000 unified network management system (hereinafter referred to as U2000) provide
the SNMP NBI to the NMS/OSS to manage the alarms.
2.1 Introduction
The Simple Network Management Protocol (SNMP) northbound interface (NBI) is one of the
NBIs provided by the U2000. The operational support systems (OSSs) can access U2000 by the
SNMP NBI to monitor and manage alarms in Huawei equipment networks.
2.2 Network Position
The SNMP NBI is deployed between the OSS and the U2000; it establishes transmissionchannels for alarm information between these two systems.
2.3 Function
The SNMP NBI supports two types of management information bases (MIBs) for different
functions. Telecommunication carriers can select an appropriate MIB to interconnect managed
devices with the OSS for network operation and maintenance (O&M) based on the following
principles.
2.4 Security Mechanism
The security mechanism used by the SNMP NBI is also the security mechanism of the SNMP
protocol. Any access to the SNMP NBI must be authenticated by the security mechanism of the
specific SNMP version (SNMPv1, SNMPv2c, and SNMPv3).
2.5 Standard Compliance
The SNMP NBI was developed based on the SNMP protocol.
2.6 Performance Indicators
The OSS manages alarms on the U2000 through the SNMP NBI. Performance indicators for the
SNMP NBI include maximum number of concurrent NMS connections, alarm forwarding
efficiency, alarm forwarding delay, and SNMP request response delay.

2.1 Introduction
The Simple Network Management Protocol (SNMP) northbound interface (NBI) is one of the
NBIs provided by the U2000. The operational support systems (OSSs) can access U2000 by the
SNMP NBI to monitor and manage alarms in Huawei equipment networks.
The SNMP protocol consists of a set of standards for network management and is the most
widely used protocol in TCP/IP networks. TCP is short for Transmission Control Protocol and
IP is short for Internet Protocol.
Huawei developed the SNMP NBI for the U2000 in compliance with industry standards. With
this NBI, OSSs can interconnect with the U2000 quickly and manage alarms on the network.
NOTE
OSSs are computer systems used by telecommunications carriers to manage performance, inventories,
services, and faults of network equipment efficiently. By function, OSSs can be classified into the serviceassurance OSS, the service provisioning OSS, and the inventory management OSS.
In this document, OSSs cover upper-layer NMSs and third-party NMSs (NMS is short for network
management system). Currently, the SNMP NBI supports alarm management only and the OSS is usually
a service assurance OSS.
2.2 Network Position
The SNMP NBI is deployed between the OSS and the U2000; it establishes transmission
channels for alarm information between these two systems.
After an alarm is generated on the equipment, the alarm is reported to the U2000 for processing.
The U2000 then reports the processed alarm to the OSS through the SNMP NBI in real time.The OSS queries, acknowledges, unacknowledges, or clears alarms on the U2000 through the
SNMP NBI.
Figure 2-1 shows the position of the SNMP NBI in a network.

2.3 Function
The SNMP NBI supports two types of management information bases (MIBs) for different
functions. Telecommunication carriers can select an appropriate MIB to interconnect managed
devices with the OSS for network operation and maintenance (O&M) based on the following
principles.
2.3.1 U2000 MIB
The U2000 MIB is used to manage transport, access, and datacom NEs or manage multi-domain NEs. When loaded with the U2000 MIB, the SNMP NBI supports automatic alarm reporting,

synchronizing, clearing, acknowledging, and unacknowledging. Alarm synchronizing is to
query active alarms.
U2000
At the U2000 side, the primary functions are:
l Reporting alarms
l Reporting heartbeat
NOTE
To enable this function, set third-party NMS parameters only on the U2000 when deploying the SNMP
NBI instead of configuring the OSS. Alarm information will be received at the preset port of the OSS
server.
After receiving alarms from the equipment or the U2000, the SNMP NBI reports these alarms
to the OSS by means of standard SNMP trap messages.
The SNMP NBI periodically reports heartbeat to the OSS. Based on the heartbeat, the OSS
determines whether the connection with the SNMP NBI is proper.
For details on trap messages, see C.3 U2000 MIB Trap.
Function Description
Subscribi
ng alarms
Subscribes alarms by alarm severity and alarm category. You can set the severity
and category when deploying the SNMP NBI.
Sets the alarm field or variable binding (VB).
Reporting
alarms
Reports alarms from NEs or the U2000.
Reporting
heartbeat
Reports heartbeat and sets the heartbeat period.
OSS
At the OSS side, the primary functions are:
l Synchronizing alarms (querying current alarms)
l
Changing filter criteria in real timel Acknowledging/Unacknowledging alarms
l Clearing alarms
NOTE
Ensure that the OSS is connected to the SNMP NBI properly before the query function is enabled.

Function Description
Synchronizing
alarms (querying
current alarms)
Queries current alarms (uncleared alarms) on the U2000 in the Set
operation.
To query current alarms on the U2000, the OSS issues the query begincommand (value: 1) in the Set operation. After receiving the
command, the SNMP agent queries current alarms from the U2000
and reports the result to the OSS. If there are too many alarms and
the query needs to be stopped, the OSS issues the query end command
(value: 0) in the Set operation. After receiving the command, the
SNMP agent stops querying and does not report the result to the OSS.
For details on alarm synchronization, see 6.1.3 Synchronizing
Alarms.
For details on trap messages, see C.3 U2000 MIB Trap.
Querying alarms by
criteria
Reports alarms by alarm severity and category. The filter criteria are
specified during alarm subscription.
You can change filter criteria in real time when loading the U2000
MIB.
Changing filter
criteria in real time
Changes filter criteria using the Set operation when the SNMP NBI
is running.
The change will take effect without restarting the SNMP NBI.
Acknowledging/
Unacknowledging
alarms
Acknowledges or unacknowledges current alarms on the U2000
based on alarm serial numbers (SNs).
Clearing alarms Clears alarms on the U2000 based on alarm SNs.
2.3.2 U2000-T MIB
The U2000-T MIB is used to be compatible with upgrades of transport NMSs. It is used to
manage only transport NEs. When the U2000-T MIB is loaded, the SNMP NBI supports
automatic alarm reporting and synchronizing. Synchronizing alarms is to query active alarms.
U2000
At the U2000 side, the primary function is automatic alarm reporting.
NOTE
To enable this function, set third-party NMS parameters only on the U2000 when deploying the SNMP
NBI instead of configuring the OSS. Alarm information will be received at the preset port of the OSS
server.
After receiving alarms from the equipment or the U2000, the SNMP NBI reports these alarms
to the OSS using standard SNMP traps. For details, see D.3 U2000-T MIB Trap.

Reportingalarms
Reports alarms from NEs or the U2000.
OSS
At the OSS side, the primary function is querying current alarms on the U2000 (current alarms
are uncleared alarms). The OSS uses the Set operation to query these alarms.
NOTE
Ensure that the OSS is connected to the SNMP NBI properly before the query function is enabled.
To query current alarms on the U2000, the OSS issues the query begin command (value: 1) in
the Set operation. After receiving the command, the SNMP agent queries current alarms from
the U2000 and reports the result to the OSS. If there are too many alarms and the query needs
to be stopped, the OSS issues the query end command (value: 0) in the Set operation. After
receiving the command, the SNMP agent stops querying and does not report the result to the
OSS.
For details on alarm synchronization, see 6.2.2 Synchronizing Alarms.
For details on traps, see D.3 U2000-T MIB Trap.
Function DescriptionQuerying
all current
alarms
Reports all alarms by default. You can stop alarm synchronization using the Set
operation.
Querying
alarms by
criteria
Reports alarms by alarm severity and category. The filter criteria are specified
during alarm subscription.
2.4 Security MechanismThe security mechanism used by the SNMP NBI is also the security mechanism of the SNMP
protocol. Any access to the SNMP NBI must be authenticated by the security mechanism of the
specific SNMP version (SNMPv1, SNMPv2c, and SNMPv3).
Figure 2-2 shows that SNMPv1 and SNMPv2c use the community-based security mechanism,
while SNMPv3 uses the user-based security mechanism.

mechanism
SNMPv1 and SNMPv2The security mechanism of SNMPv1 and SNMPv2c is community-based: the NMS
authenticates NEs based on the community name list and the agent does not check the validity
of the community name. SNMP packets are transferred without encryption. Therefore,
authentication security and confidentiality are not well guaranteed.
l Before the Get, Get Next, or Set operation, the NMS must know the read and write
community names configured for the agent.
l For trap and inform packets, the community name is the read community name configured
for the agent.
NOTE
SNMPv1 does not support the inform mode.
SNMPv3
The security mechanism of SNMPv3 is user-based. In terms of security, SNMPv3 emphasizes
data security and access control and therefore offers a higher level of security than SNMPv1 and
SNMPv2c.
In data security, SNMPv3 provides protection for SNMP packets in the following ways:
l Data integrity check
The data cannot be modified in an unauthorized manner. Any changes in the data sequence
are limited to the allowed extent.
l Data origin authentication
SNMPv3 authenticates users from whom received packets are sent rather than applications
that generate these packets.
l Data confidentiality check
When the NMS or agent receives a packet, it checks when the packet was generated. If the
interval between the creation time and the system time exceeds the preset time range, this
packet will be discarded. This check prevents packets from being maliciously modified and
malicious packets from being received.
In access control, the NMS performs security checks on managed objects (MOs) based onSNMPv3.

3.1 Overview
SNMP is one of the widely applied NMS protocols in the TCP/IP network.
As a widely applied industry standard for the NMS protocols, the SNMP aims:
l To transmit the management information between two nodes.
l To help the manager to search and modify the information, and locate faults at any node
in the network.
l To help the manager to diagnose the faults, configure the capacity, and generate reports.
The features of the SNMP are as follows:
l Uses the polling mechanism and provides a basic function set.
l Fits small, fast and cost effective network.
3.2 Network Management Framework
The Simple Network Management Protocol (SNMP) is a set of protocols and standards. It
provides channels for the OSS to collect network management data from network equipment
and for network equipment to report problems and errors to the OSS.
The SNMP network management framework consists of the network management system
(NMS), agent, management information base (MIB), and SNMP protocols. Figure 3-1 illustrates
relationships between them.
NOTE
In SNMPv3, both the NMS and the agent are called an entity.

l NMS
An independent system that runs network management applications.
The NMS performs the following operations:
– Send query packets to NEs.
– Receive responses or traps from NEs.

Processes that run on NEs.
The SNMP agent performs the following operations:
– Receive, parse, and authenticate query packets from the NMS.
– Search the MIB tree, call other modules for operation, and obtain responses.
– Construct response packets and send them to the NMS.
– Send traps to the NMS if urgent.
l MIB
A collection of equipment that the agent can query or set.
The agent queries the MIB for required operations.
l SNMP
An application-layer protocol carried over UDP in the TCP/IP structure.
Exchanges management information between the NMS and agents.
Figure 3-2 shows the position of SNMP in the TCP/IP family.

NOTE
For the SNMP NBI, the agent is running on the U2000 and the NMS refers to the OSS. Currently two MIBs
are supported: U2000-T MIB andU2000 MIB. For details, see C U2000 MIB and D U2000-T MIB.
3.3 SNMP Message Structure
The SNMP message structure also refers to protocol data units (PDUs) or SNMP packet types.
PDUs are used for communication between the NMS and agents. Figure 3-3 shows five PDUs.

l GetRequest: The PDU that the NMS uses to visit the agent and obtains one or several
parameter values.
l GetNextRequest: The PDU that the NMS uses to visit the agent and obtains the next
parameter value.
l SetRequest: The PDU that the NMS uses to visit the agent and sets one or more parameter values.
l GetResponse: The PDU that the agent uses to return one or more parameter values to the
NMS as responses to GetRequest, GetNextRequest, and SetRequest packets.
l Trap: The PDU that the agent uses to send traps to inform the NMS of important events or
state changes that occurred in NEs.
GetRequest, GetNextRequest, and SetRequest packets are sent from the NMS to agents while
GetResponse and trap packets are sent from agents to the NMS.
3.4 MIBMIB is a key part of the SNMP network management framework.
NOTE
For U2000, the MIB defines managed objects that are used by the function interfaces of the SNMP NBI. These
definitions are extremely important for the U2000 in that they determine what operations the OSS can perform
and what network management information the OSS can obtain.
The MIB covers all managed objects (MOs) and refers to a group of SNMP-based entities. The
MIB structure resembles a tree, so it is also called a MIB tree. Each MO is mapped to a leaf
node, also called an object or object identifier (OID). The MIB tree is static in that after the agent
is started and the MIB is initialized, the NMS queries or modifies MOs based on the current
MIB. The NMS manages the MIB in read and write mode.
All MOs in a network are displayed as a leaf node in the MIB tree. An MO is identified by OID,
a unique path that originates from the root node to the leaf node.
An OID consists of a set of integers greater than or equal to 0 and is used to identify an MO in
the MIB tree. The structure of management information (SMI) ensures that an MO is mapped
to a unique OID.
Once the MIB file is released, OIDs are bound to related MOs and this binding cannot be
modified. A MO in the MIB cannot be deleted, but can be set to obsolete indicating that this
MO is not no longer used.

3.5 SNMP Packet Operation Process
This topic uses the SNMPv1 as an example to introduce the operation process of SNMP packet.
The agent on the managed node receives a request packet from the NMS through UDP port.
U2000 use 9812 by default.
The agent treats the received packet as follows:
1. Decoding the packet based on basic encoding rules of ASN.1 and representing it in an
internal data structure
The agent discards the packet if some errors cause the decoding failure.
2. Checking the SNMP version number contained in the packet
The agent fetches the version number from the packet and compares it with the version that
it supports. If they are inconsistent, the agent discards the packet.
3. Checking the community name contained in the packet
The community name is inserted by the NMS. If the community name is not the supported
one, the agent discards the packet. A trap packet is returned to the NMS at the same time.SNMPv1 provides weak security measures, which are enhanced in SNMPv3.

4. Fetching the PDU from the authenticated ASN.1 object
If the operation fails, the agent discards the packet.
5. Handling the PDU
The agent handles the PDU according to its type. It searches the MIB to find the MO
matching the variable, and then obtains the value of the variable from the module. After
that, the agent generates the response packet, encodes it and returns it to the NMS.
6. The NMS performs the same operations as the agent, and displays the final result.
3.6 Version Evolution
Currently there are three SNMP versions: SNMPv1, SNMPv2c, and SNMPv3, all of which are
supported by the SNMP NBI.
SNMPv1
l Mutual access to management information between the NMS (also called SNMP manager)
and SNMP agent.
l Operations include:
– Get
– Set
– Trap
l Protocol data units (PDU) are:
– GetRequest
– GetNextRequest
– GetResponse
– SetRequest
– Trap
l Community-based security model
NOTE
The OSS must get the community information from the U2000 administrator.
SNMPv2c
SNMPv2 inherits all functions in SNMPv1 and provides the following new features:
l Mutual access to management information between SNMP managers.
l Operations include:
– GetBulk
– Inform
– Report
l The format of traps is modified to the same as that of the Get and Set packets.
l SNMPv2 provides fractionalized error codes.
NOTE
The OSS must get the community information from the U2000 administrator.

l Northbound interface is an optional component of the U2000. A license is required for
using this function.
l If you do not install the northbound interface component during the installation of the
U2000, you need to add it manually.
l The northbound interface is a System single-instance deployment package. Therefore, only
one instance can be deployed.
CAUTION
l After the northbound interface component is installed or added, you need to add a
corresponding instance and configure parameters. Then, the U2000 can start the NBI-related
process.
l After initializing the database of the U2000, you need to configure the northbound interface
instance again.
l After the northbound interface instance is configured, you need to restart all the NMS
services.
l You can configure only one IP address for one network interface. It is not allowed to set
multiple IP addresses for the same network interface. It is suggested that configure multiple
network interface for multiple IP address.
l If the NAT is used to transform addresses between the Msuite server and clients, deploy the
NBI on the Msuite client that installed on the U2000 server. Otherwise, the NBI may be
failure to deploy.
l The U2000 server and the OSS must can communicate with each other. Otherwise, the OSS
cannot interconnect with the NBI of the U2000. Therefore, if the U2000 server is configured
with multiple network interface cards (NICs) and the NICs are in different network segments,
set the IP address for connecting to the OSS as the IP address of the U2000 server.
l You must configure the northbound interface again after the IP of NMS changed.
Terms
The following explains certain confusable terms:
l Component: It is the software functional unit that you can choose to install. Each component
can include multiple deployment packages.
l Deployment package: It is the software unit deployed on a computer. In distributed mode,
the deployment packages of one component may be deployed on different computers.
According to the quantity of the instances supported, you can classify the deployment packages into the following types:

CAUTION
The trap-transmitting IP address and request-receiving IP address are both the U2000 server
IP address. Ensure that this IP address can be used for successful communication betweenthe U2000 and the OSS.
Refer to chapter "U2000 Port List" in the iManager U2000 Administrator Guide and the
iManager U2000 Planning Guide before you configure ports for the SNMP NBI. Before
configuring these ports, ensure that the specified ports are idle.
Do not use the default ports of the SNMP protocol (port 161 and port 162) to deploy the
SNMP NBI, because they are occupied by other processes.
2. Select the SNMP version. You also need to set the security level, authentication protocol,
and data encryption protocol if the version is set to v3.
By default, the SNMP version is v1.
Step 4 Click Third-Party NMS and set parameters for the OSS.
For parameter definitions, see B.1.2 Third-Party NMS.
1. Set the trap receive IP address/port. The trap receive IP address is the IP address of the OSS
server. The port is 6666 by default.

http://slidepdf.com/reader/full/u2000-snmp-nbi-user-guide-v100r006c0205 47/175
NOTE
The Receive Trap Address is not the IP address of the U2000 server.
Currently a maximum of 10 third-party NMSs are supported.
The same SNMPv3 user configured for different third-party NMSs, for example, NMS 1 and NMS
2, must use the same authentication and encryption passwords
When the U2000-T MIB is used, the SNMP NBI identifies OSSs by read or write community.
l If multiple OSSs use the same read or write community, only the first OSS gets the synchronized
results when any of the OSSs tries to synchronize data.
l It is recommended that each OSS uses a unique read or write community so that the OSS can get
correct synchronized results.
CAUTION
In a Linux-based HA system, if the floating IP address function is enabled during NMS
installation, set Send Trap address and Receive Request from NMS address to floatingIP addresses.
2. Set SNMP security parameters. For security concern, input parameters are encrypted. For
example, to set Read Community, click next to Read Community and set parameters
in the Set Password dialog box.
The following are the default security parameters. Modifying these parameters is
recommended for security concern.
l If the SNMP version is set to v1 or v2c, configure the read and write communities. By
default, the read community is Changeme_123 and the write community is
Changeme_123.
l If the SNMP version is set to v3, configure the V3 User Name, V3 Authentication
Password, and V3 Privacy Password for SNMPv3 users.
l By default, the user name is admin and the two passwords are blank.

CAUTION
In the case of SNMPv3, the V3 User Name is required. If no user name is entered, the
SNMP service process cannot start after deployment.To ensure the security of the U2000, passwords must be complex enough. For example, a
password must contain eight or more characters of two types. The allowed characters are
digits, letters, and special characters. Remember to change passwords regularly.
The password must meet the following requirements to safeguard your user account.
l Consists more than 8 characters.
l The password cannot be the user name or its reverse spelling.
l The password must consist of three of the following types of characters at least:
l Lower-case letters
l Upper-case letters
l Digits
l Special characters including ~ ! @ # $ % ^ & * ( ) - _ = + \ |[ { } ] ; : ' " , < . > / ?
and space
3. Set the alarm filter criteria, including Alarm Level and Alarm Category.
NOTE
Alarms are reported to the OSS based on the defined alarm severity and category.
The OSS can change the filter criteria in real time. For details, see 6.1.2 Changing Filter Criteria.
Fault: Indicates that the SNMP NBI will report alarm generation and alarm clearance. That is, the second
and third places of the value of AlarmCategoryFilter in binary mode are set to 0 when the
thirdNMSFaultFilter subinterface is invoked.
Event alarm reporting is disabled by default and cannot be configured by using the Msuite. But you can
enable this function by following methods.
l You can enable event alarm function manually. For details, see 7.3.10 How to report the event
alarm.
l To configure event alarm reporting, you can invoke the thirdNMSFaultFilter subinterface and set
the first place of the value of AlarmCategoryFilter in binary mode to 0.

5 Configuring the SNMP NBI on the OSS
About This Chapter
After the SNMP NBI was deployed properly, the OSS can receive real-time alarms. To connect
to the U2000 and enable operations on reported alarms (such as synchronize, acknowledge,
unacknowledge, and clear alarms), you need also load the appropriate MIB file to the OSS and
set relevant parameters. A maximum of ten OSSs can be connected concurrently to the
U2000. For the NMS connection, SNMPv1, SNMPv2c, and SNMPv3 can be used.
5.1 Configuring the SNMPv1 or SNMPv2c NBI
The OSS connects to the U2000 through SNMPv1 and SNMPv2c NBIs by using communities
for access authentication. Configurations are similar for SNMPv1 and SNMPv2c NBIs.Parameters include the request receive IP address/port on the U2000, SNMP version, and read/
write communities.
5.2 Configuring the SNMPv3 NBI
Compared to SNMPv1 and SNMPv2c, the SNMPv3 NBI is characterized by higher security due
to its user-based security mechanism. In this mechanism, user names and passwords are used
for access authentication and packet data is encrypted. Parameters include the request receive
IP address/port on the U2000, SNMP version, security level, authentication/encryption protocol,
and authentication/encryption password.

6 Calling the SNMP NBI
About This Chapter
The OSS calls SNMP subinterfaces to perform operations such as alarm synchronization on the
U2000. Available interfaces vary with the loaded MIB (U2000-T MIB or U2000 MIB).
NOTE
Ensure that the OSS has connected to the U2000 through the SNMP NBI and the desired operations have
been licensed for use.
6.1 U2000 MIB Subinterfaces
When the OSS is loaded with the U2000 MIB, the SNMP NBI provides subinterfaces to enable
the following functions: reporting alarms automatically, and synchronizing, clearing,confirming, acknowledging, unacknowledging, and filtering alarms.
6.2 U2000-T MIB Subinterfaces
When the OSS is loaded with the U2000-T MIB, the SNMP NBI provides subinterfaces to enable
the following functions: reporting alarms automatically and synchronizing alarms.

6.1 U2000 MIB Subinterfaces
When the OSS is loaded with the U2000 MIB, the SNMP NBI provides subinterfaces to enable
the following functions: reporting alarms automatically, and synchronizing, clearing,
confirming, acknowledging, unacknowledging, and filtering alarms.
CAUTION
Ensure that the U2000 MIB has been loaded to the OSS. To load the U2000 MIB, set the MIB
type to U2000 MIB when deploying the SNMP NBI.
6.1.1 Reporting Real-Time AlarmsYou do not need to set any parameters for the OSS to receive alarm packets from the U2000
through the SNMP NBI. After the SNMP NBI is properly deployed on the U2000, alarms will
be reported to the OSS in real time.
Context
The SNMP NBI component has been installed and the SNMP NBI instance has been configured
on the U2000.
After the trap-receiving IP address or port and SNMP version have been set for the OSS on the
U2000, the OSS can receive real-time alarms.
You do not need to set related parameters on the OSS. Ensure that the OSS is properly connected
to the U2000 and the related ports are permitted by the firewall.
For details on how to deploy and configure the SNMP NBI, see 4 Deploying and Configuring
SNMP.
6.1.2 Changing Filter Criteria
The SNMP NBI allows the OSS dynamically to change filter criteria during its running so only
required alarms are reported.
Function
The OSS can call the alarm filter interface to change alarm filter criteria dynamically when the
SNMP NBI is working.

Procedure
The OSS sets thirdNMSFaultFilter to 10.70.73.97:6666:0011:100111.
The OSS receives responses from the U2000, indicating that the filter criteria are changed
successfully. The OSS will then receive the required alarms only.
6.1.3 Synchronizing Alarms
The SNMP NBI allows the OSS to initiate the synchronization operation to ensure that the alarminformation on the OSS and the U2000 is consistent.
Function
The UDP-based SNMP protocol cannot guarantee that all alarms are reported to the OSS and
some alarm packets may be lost. Therefore, the OSS synchronizes alarms to ensure alarm data
consistency and can also stop synchronization.
After the synchronization starts, the U2000 sends traps through the SNMP NBI to inform the
OSS that the alarm synchronization is started.
When the synchronization is complete or stopped, the U2000 will send traps through the SNMP
NBI to inform the OSS that the alarm synchronization is ended.
Figure 6-1 shows the alarm synchronization process.

6.2 U2000-T MIB Subinterfaces
When the OSS is loaded with the U2000-T MIB, the SNMP NBI provides subinterfaces to enable
the following functions: reporting alarms automatically and synchronizing alarms.
CAUTION
Ensure that the U2000-T MIB has been loaded to the OSS. To load the U2000-T MIB, set the
MIB type to U2000-T MIB when deploying the SNMP NBI.
6.2.1 Reporting Real-Time Alarms
You do not need to set any parameters for the OSS to receive alarm packets from the U2000through the SNMP NBI. After the SNMP NBI is properly deployed on the U2000, alarms will
be reported to the OSS in real time.
Context
The SNMP NBI component has been installed and the SNMP NBI instance has been configured
on the U2000.
After the trap-receiving IP address or port and SNMP version have been set for the OSS on the
U2000, the OSS can receive alarms in real time.
You do not need to set related parameters on the OSS. Ensure that the OSS is properly connected
to the U2000 and the related ports are permitted by the firewall.
For details on how to deploy and configure the SNMP NBI, see 4 Deploying and Configuring
SNMP.
CAUTION
The reported alarm field for the U2000-T MIB consists of 36 bound variables (VBs). For details,
see D.2 Reported Alarm Field by U2000-T MIB.
6.2.2 Synchronizing Alarms
The SNMP NBI allows the OSS to initiate the synchronization operation to ensure that alarms
on the OSS and the U2000 are consistent.
Function
The UDP-based SNMP protocol cannot guarantee that all alarms are reported to the OSS and
some alarm packets may be lost. Therefore, the OSS synchronizes alarms to ensure alarm data
consistency and can also stop the synchronization.
After the synchronization starts, the U2000 sends traps through the SNMP NBI to inform theOSS that the alarm synchronization is started.

7.1 Maintenance Description
This section describes the basic requirement of maintenance SNMP NBI.
To ensure that the SNMP NBI works well, there are some requirements as follows:
1. The maintenance personnel must be familiar with:
l Windows or the Sun workstation - Solaris 8 or Solaris 10, and Linux
l The SNMP protocol
l Basic concepts of the Telecommunication Management Network (TMN)
2. The U2000 Server runs normally.
3. The License support SNMP NBI function.
4. The parameter is correct when you deploy the SNMP NBI by Msuite.
7.2 Deleting and Disabling an SNMP Interface
This topic describes how to disable or delete an SNMP interface when the U2000 temporarily
need not provide this interface to an external network.
7.2.1 Logging In to the System Monitor Client
The U2000 System Monitor Client uses the client/server model. To perform an operation, you
need to log in to the server through the U2000 client.
Prerequisites
Before login, ensure that the U2000 client and server are connected properly and that the server
works correctly.
Context
l The default port number of the server is 31030. Do not change it in normal conditions.
Otherwise, you cannot log in to the U2000 server.
l The login modes include the SSL mode and common mode. In SSL mode, the data is
encrypted when being transmitted between the client and the server. In common mode, the
data is not encrypted during transmission. To ensure the security of data transmission, youare recommended to use the Security (SSL) mode.
l The port used for login in common mode is different from that in SSL mode. The port
number is 31030 in common mode, and 31080 in security (SSL) mode.
l After last login, if you do not log in again during the preset period, your account hibernates
or the U2000 deletes the account.
l If you never use a new user account for login, the U2000 does not invalidate or delete the
account.

7.3.2 SNMP Service Process Fails to Be StartedSymptom
After the SNMP NBI is configured, the SNMP service process fails to be started.
Possible Causes
Port 9812 for configuring the SNMP NBI is occupied by other processes.
The V3 User is blank when use the SNMP v3.
CAUTION
Do not use the default ports of the SNMP protocol (port 161 and port 162) to configure the
SNMP NBI, because these they are occupied by other processes.
Refer to chapter "U2000 Port List" in the iManager U2000 Administrator Guide and the
iManager U2000 Planning Guide before you configure ports for the SNMP NBI.
Procedure
Step 1 Check whether other processes are using the port of the SNMP service.
Run the netstat -an command to view the service ports opened by the system.
l On the Solaris or Linux OS, run the netstat -an | grep port_number command to view the
status of a specified port.
For example, run the netstat -an | grep 6666 command to view the status of port 6666.
l In the Windows OS, run the netstat -an | find "port_number" command to view the status
of a specified port.
For example, run the netstat -an | find "6666" command to view the status of port 6666.
NOTE
If any router or firewall is located on the network between the U2000 and the OSS, you must check the ports used by the U2000 and the OSS and ensure that these ports can be opened for normal communication.

A Relations Between License and SNMP
Interface
This part introduces the relations between license and SNMP interface.
The U2000 license controls the software of SNMP interface in the following three dimensions:
l Interface function
l Technical domain
l Management capacity
The three dimensions depend on each other. The U2000 divides the license according to the
dimensions to dynamically control the SNMP software.
For details of Dimension, refer to Figure A-1 and Table A-1.

Parameters
NOTE
The Receive Trap Address is not the IP address of the U2000 server.
Currently a maximum of 10 third-party NMSs are supported.
The same SNMPv3 user configured for different third-party NMSs, for example, NMS 1 and NMS 2, mustuse the same authentication and encryption passwords
When the U2000-T MIB is used, the SNMP NBI identifies OSSs by read or write community.
l If multiple OSSs use the same read or write community, only the first OSS gets the synchronized
results when any of the OSSs tries to synchronize data.
l It is recommended that each OSS uses a unique read or write community so that the OSS can get
correct synchronized results.

a response to the previous alarm reporting.
l Inform mode: A received alarm is reported immediately after the OSS returns a response to
the previous alarm reporting or the retried times is excessed. In this mode, if the parameters
configured for the OSS are incorrect, the SNMP agent tries connecting to the OSS for many
times. This will occupy a large number of resources. As a result, the efficiency of the SNMP
agent is reduced. Therefore, exercise caution when you set this parameter to Inform.
l The SNMPv1 supports the Trap mode only.

and downstream NEs connected by services.
After alarm correlation rules are enabled on the U2000, the NBIs report correlative alarms based on the
alarm correlation analysis results on the U2000 and different NBIs have different rules for reporting
correlative alarms. The SNMP NBI supports only trail-based correlative alarms.
B.2.7 Engineering Alarm
During engineering commissioning or service cutover, a large number of alarms are generated
on NEs. If you set the NEs in engineering maintenance state, generated alarms are displayed as
engineering alarms. You can specify whether to report the engineering alarms.

C.4.4 Active Alarm Synchronization End Trap
Active alarm synchronization end traps are triggered when all required alarms have been reported
to the OSS or the OSS automatically stops the synchronization.
Synchronization Stopped After Alarm Reporting Was Complete
After all required alarms are reported to the OSS, the U2000 sends traps through the SNMP NBI
to inform the OSS that the alarm reporting is complete.

During the synchronization, the OSS automatically interrupts the process. The U2000 then
reports traps to inform the OSS that the synchronization is stopped as a response to the request.

E.1 Notes and Precautions
In the practical communication process, the source (the server) and the sink (the client) use
relevant ports. Usually you only need to specify the source port, and the sink port is dynamically
created.
Note the following during the project implementation:
l The service ports used by the NMS should not be closed. Run the following command to
view the system service ports:
netstat -an
l If there are routers or firewalls between the source and the sink, check all ports used by the
source and the sink. Make sure that these ports can be normally turned up to support the
communication between the source and sink.
E.2 Port Used Between the U2000 Server and the OSS
This topic describes the port used between the U2000 server and the OSS.
If a firewall is deployed between the U2000 server and the OSS, ensure that any port on the OSS
can set up connections with ports on the U2000 through the firewall. For ports used by the U2000,
see U2000 Communication Port Matrix.
