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.

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 

allow or prohibit SNMP packets with a specific source IP address, so as to allow or prohibit the specified 

NMS to access the agent by using this user name. 

Use the snmp-agent usm-user { v1 | v2c } command to add a user to an SNMP group. 

Use the undo snmp-agent usm-user { v1 | v2c } command to delete a user from an SNMP group. 

As defined in the SNMP protocol, in SNMPv1 and SNMPv2c networking applications, the NMS and the 

agent use community name to authenticate each other; in SNMPv3 networking applications, they use 

user name to authenticate each other. If you prefer using the user name in the authentication, the 

device supports configuration of SNMPv1 and SNMPv2c users. Creating an SNMPv1 or SNMPv2c user
