SNMPv3 configuration example
Network requirements
As shown in Figure 44 , 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 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.

# Add the user managev3user to the SNMPv3 group managev3group, and set the authentication

privacy key to 123456TESTencr&!.

2. Configure the SNMP NMS:
{
Specify SNMPv3.
{
Create the SNMPv3 user managev3user.
{
Enable both authentication and privacy functions.
{
Use SHA-1 for authentication and AES for encryption.
