# Enable SNMP traps, set the NMS at 1.1.1.2 as an SNMP trap destination, and use public as the
community name. (To make sure the NMS can receive traps, specify the same SNMP version in the
snmp-agent target-host command as is configured on the NMS.)
[Agent] snmp-agent trap enable
[Agent] snmp-agent target-host trap address udp-domain 1.1.1.2 params securityname
public v1
[Agent] quit
2. Configure the SNMP NMS:
# Configure the SNMP version for the NMS as v1 or v2c, create a read-only community and name
it public, and create a read and write community and name it private. For information about
configuring the NMS, see the NMS manual.
NOTE:
The SNMP settings on the agent and the NMS must match.
3. Verify the configuration:
# Try to get the count of sent traps from the agent. The attempt succeeds.
Send request to 1.1.1.1/161 ...
Protocol version: SNMPv1
Operation: Get
Request binding:
1: 1.3.6.1.2.1.11.29.0
Response binding:
1: Oid=snmpOutTraps.0 Syntax=CNTR32 Value=18
Get finished
# Use a wrong community name to get the value of a MIB node from the agent. You can see an
authentication failure trap on the NMS.
1.1.1.1/2934 V1 Trap = authenticationFailure
SNMP Version = V1
Community = public
Command = Trap
Enterprise = 1.3.6.1.4.1.43.1.16.4.3.50
GenericID = 4
SpecificID = 0
Time Stamp = 8:35:25.68
SNMPv3 configuration example
Network requirements
As shown in Figure 25 , 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.
