Perform SNMP Get operation on the NMS to obtain the value of the MIB node.
Alarm group configuration example
Network requirements
As shown in
, Agent is connected to a console terminal through its console port and to an NMS
across Ethernet.
Do the following:
•
Connect Ethernet 1/0/1 to the FTP server. Gather statistics on traffic of the server on Ethernet
1/0/1 with the sampling interval being five seconds. When traffic is above or below the thresholds,
Agent sends the corresponding traps to the NMS.
•
Execute the
display rmon statistics
command on Agent to display the statistics, and query the
statistics on the NMS.

Configuration procedure
# Configure the SNMP agent, and make sure that the SNMP settings are the same as on the NMS. This
example sets the SNMP version to SNMPv1, read community to
public
, write community to
private
, and
the trap destination to
1.1.1.2
, the IP address of the NMS.
