Configuration procedure

1) Configuring the agent

# Configure the IP address of the agent as 1.1.1.1/24 and make sure that there is a route between the

agent and the NMS. (The configuration procedure is omitted here)

# Configure the access right: the user can read and write the objects under the interface node with the

OID of 1.3.6.1.2.1.2, and cannot access other MIB objects. Set the user name to managev3user,

authentication protocol to MD5, authentication key to authkey, the privacy protocol to DES56, and the

privacy password to prikey.

2) Configuring the SNMP NMS

SNMPv3 uses an authentication and privacy security model. On the NMS, the user needs to specify the

username and security level, and based on that level, configure the authentication mode, authentication

password, privacy mode, and privacy password. In addition, the timeout time and number of retries

should also be configured. The user can inquire and configure the device through the NMS.

The configurations on the agent and the NMS must match.

3) Verify the configuration

After the above 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.
