Use undo snmp-agent trap source 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 uses 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.
Before you can configure the IP address of a particular interface as the source IP address of the trap,
make sure that the interface already exists and that it has a legal IP address. Otherwise, if the configured
interface does not exist, the configurations fails. If the specified IP address is illegal, the configuration
becomes invalid. When a legal IP address is configured for the interface, the configuration automatically
becomes valid.

3: Manage level
Parameters
v1: Specifies SNMPv1.
v2c: Specifies SNMPv2c.
group-name: Group name, a case-sensitive string of 1 to 32 characters.
acl acl-number: Specifies a basic ACL to filter NMSs by source IPv4 address. The acl-number argument
represents a basic ACL number in the range of 2000 to 2999. Only the NMSs with the IPv4 addresses
permitted in the ACL can use the specified username (community name) to access the SNMP agent.
Description
Use snmp-agent usm-user { v1 | v2c } to add a user to an SNMPv1 or SNMPv2c group.
Use undo snmp-agent usm-user { v1 | v2c } to delete a user from an SNMPv1 or SNMPv2c group.
Make sure you have created the SNMPv1 or SNMPv2c group.
In FIPS mode, this command is not available and only SNMPv3 settings can be configured.
When you create an SNMPv1 or SNMPv2c user, the system automatically creates a read-only
community that has the same name as the SNMPv1 or SNMPv2c username. To change the access right
of this community to write access, use the snmp-agent community command or the snmp-agent group
