Configuring the NMS
The configuration on the NMS must be consistent with that on the agent. Otherwise, you cannot
perform corresponding operations.
To configure the NMS:
1.
Configure the SNMP version for the NMS as v1 or v2c.
2.
Create a read-only community and name it
public
.
3.
Create a read and write community and name it
private
.
For information about how to configure the NMS, see the NMS manual.
Verifying 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.
Disable or enable an idle interface on the agent, and you can see the interface state change traps on
the NMS.
SNMPv3 configuration example
Network requirements
As shown in Figure 104 , the NMS (1.1.1.2/24) uses SNMPv3 to monitor and manage the interface
status of the AP (the agent) at 1.1.1.1/24, and the AP 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 AP also
encrypt the SNMP packets between them by using the DES56 algorithm and the privacy key
prikey
.
