Optional) Configuring The Trap Function - Huawei NetEngine5000E Configuration Manual

HUAWEI NetEngine5000E Core Router
Configuration Guide - System Management
Follow-up Procedure
After the access rights are configured, especially after the IP address of the NM station is
specified, if the IP address changes (for example, the NM station changes its location, or IP
addresses are reallocated due to network adjustment), you need to change the IP address of the
NM station in the ACL. Otherwise, the NM station cannot access the device.

3.2.3 (Optional) Configuring the Trap Function

This section describes how to specify the alarms to be sent to the NM station, which help you
to locate important problems. After relevant parameters are set, the security of alarm sending
can be improved.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
snmp-agent trap enable
Alarm sending is enabled.
Step 3 Run:
snmp-agent trap enable feature-name feature-name trap-name trap-name
A trap function of a feature module is enabled. This means that an alarm of a specified feature
can be sent to the NM station.
Step 4 Run:
snmp-agent trap source interface-type interface-number
The source interface for trap messages is specified.
After the source interface is specified, its IP address becomes the source IP address of trap
messages. Configuring the IP address of the local loopback interface as the source interface is
recommended, which can ensure device security.
The source interface specified on the router for trap messages must be consistent with that
specified on the NM station; otherwise, the NM station does not accept the trap messages sent
from the router.
Step 5 Run:
commit
Issue 01 (2011-10-15)
NOTE
If the snmp-agent trap enable command is run to enable the trap functions of all modules, or the snmp-
agent trap enable feature-name command is run to enable three or more trap functions of a module, note
the following points:
l To disable the trap functions of all modules, you need to run the snmp-agent trap disable command.
l To restore the trap functions of all modules to the default status, you need to run the undo snmp-agent
trap enable or undo snmp-agent trap disable command.
l To disable one trap function of a module, you need to run the undo snmp-agent trap enable feature-
name command.
