The Cisco router must be configured to send SNMP traps and notifications to the SNMP manager for the purpose of sending alarms and notifying appropriate personnel as required by specific events.

| Description |
|---|
| If appropriate actions are not taken when a network device failure occurs, a denial of service condition may occur which could result in mission failure since the network would be operating without a critical security monitoring and prevention function. Upon detecting a failure of any router components, the router must activate a system alert message, send an alarm, or shut down. By immediately displaying an alarm message, potential security violations can be identified more quickly even when administrators are not logged into the device. This can be facilitated by the router sending SNMP traps to the SNMP manager that can then have the necessary action taken by automatic or operator intervention. |

| Verify that the router is configured to send traps to the SNMP manager. The SNMP configuration should contain commands similar to the example below. snmp-server host 10.1.3.44 traps private snmp-server traps rf snmp-server traps bfd snmp-server traps ethernet cfm snmp-server traps ntp snmp-server traps ethernet oam events snmp-server traps copy-complete snmp-server traps snmp linkup snmp-server traps snmp linkdown snmp-server traps snmp coldstart snmp-server traps snmp warmstart snmp-server traps snmp authentication … … … snmp-server traps entity-state operstatus snmp-server traps entity-state switchover snmp-server traps entity-redundancy all snmp-server traps entity-redundancy status snmp-server traps entity-redundancy switchover Note: The above is a subset of all the possible traps that can be enabled. Selective traps can be enabled as required. If the router is not configured to send traps to the SNMP manager, this is a finding. |
