Network requirements

As shown in Figure 48, the NMS (1.1.1.2/24) uses SNMPv3 to monitor and manage the interface status of the agent (1.1.1.1/24). The agent automatically sends notifications to report events to the NMS. The default UDP port 162 is used for SNMP notifications.

The NMS and the agent perform authentication when they establish 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&!.
