Verifying the configuration
• After the configuration, an SNMP connection is established between the NMS and the agent.
The NMS can get and configure the values of some parameters on the agent through MIB
nodes.
• Disable or enable an idle interface on the device, and the NMS receives the corresponding trap.
SNMPv3 configuration example
Network requirements
As shown in Figure 527, the NMS (1.1.1.2/24) uses SNMPv3 to monitor and manage the interface
status of the agent (1.1.1.1/24), and the agent automatically sends traps to report events to the NMS.
The NMS and the agent perform authentication when they set up an SNMP session. The
authentication algorithm is MD5 and the authentication key is authkey. The NMS and the agent also
encrypt the SNMP packets between them by using the DES algorithm and the privacy key prikey.
