Snmp-Agent Usm-User { V1 | V2C - H3C S5120-SI Series Command Reference Manual

Description
Use the snmp-agent trap source command to specify the source IP address contained in the trap.
Use the undo snmp-agent trap source command to restore the default.
By default, SNMP chooses the IP address of an interface to be the source IP address of the trap.
Upon the execution of this command, the system uses the primary IP address of the specified interface
as the source IP address of the traps, and the NMS will use this IP address to uniquely identify the agent.
Even if the agent sends out traps through different interfaces, the NMS uses this IP address to filter all
traps sent from the agent.
Use this command to trace a specific event by the source IP address of a trap.
Note that:
Before you can configure the IP address of a particular interface as the source IP address of the trap,
ensure that the interface already exists and that it has a legal IP address. Otherwise, if the configured
interface does not exist, the configurations will fail; if the specified IP address is illegal, the configuration
will be invalid. After a legal IP address is configured for the interface, the configuration becomes valid
automatically.
Related commands: snmp-agent trap enable, snmp-agent target-host.
Examples
# Configure the IP address for the Vlan-interface 1 as the source address for traps.

Parameters
v1: The configured user name should be applied in the SNMPv1 networking environment. If the agent
and the NMS use SNMPv1 packets to communicate with each other, this keyword is needed.
v2c: The configured user name should be applied in the SNMPv2c networking environment. If the agent
and the NMS use SNMPv2c packets to communicate with each other, this keyword is needed.
user-name: User name, a string of 1 to 32 characters. It is case sensitive.
group-name: Group name, a string of 1 to 32 characters. It is case sensitive.
acl acl-number: Associates a basic ACL with the user. acl-number is in the range 2000 to 2999. By
using a basic ACL, you can restrict the source IP address of SNMP packets, that is, you can configure to
1-26
