Step 1: Add (/ discover) the router in your LAN making sure the SNMP read and write communities are configured properly for the router.
Step 2: Configure the Cisco router to send traps to OpManager. Alerts are shown based on the traps received in OpManager. To configure OpManager server as the SNMP server receiving traps for the routers, telnet the router and type the following command:
snmp-server host traps rtr
For instance, if the OpManager host IP Address is 192.168.18.128, and the community string is private, the command would be:
snmp-server host 192.168.18.128 traps private rtr
