SNMPv3 configuration example

Network requirements
As shown in
of the agent (1.1.1.1/24). The agent automatically sends notifications to report events to the NMS.
The NMS and the agent perform authentication when they set up an SNMP session. The authentication
algorithm is SHA- 1 and the authentication key is 123456TESTauth&!. The NMS and the agent also
encrypt the SNMP packets between them by using the AES algorithm and the privacy key
123456TESTencr&!.

Configuration procedure
1.
Configure the agent:
# Configure the IP address of the agent, and make sure the agent and the NMS can reach each
other. (Details not shown.)
# Assign the NMS (SNMPv3 group managev3group) read and write access to the objects under
the snmp node (OID 1.3.6.1.2.1.11), and deny its access to any other MIB object.
