Controlling and Monitoring Failover

Monitoring Failover

When a failover occurs, both FWSMs send out system log messages. This section includes the following
topics:

Failover System Log Messages

FWSM issues a number of system log messages related to failover at priority level 2, which indicates a
critical condition. To view these messages, see the Catalyst 6500 Series Switch and Cisco 7600 Series
Router Firewall Services Module System Log Messages to enable logging and to see descriptions of the
system log messages.
During switchover, failover will logically shut down and then bring up interfaces, generating system log
Note
messages 411001 and 411002. This is normal activity.

Debug Messages

To see debug messages, enter the debug fover command. See the Catalyst 6500 Series Switch and Cisco
7600 Series Router Firewall Services Module Command Reference for more information.
Because debugging output is assigned high priority in the CPU process, it can drastically affect system
Note
performance. For this reason, use the debug fover commands only to troubleshoot specific problems or
during troubleshooting sessions with Cisco TAC.

SNMP

To receive SNMP syslog traps for failover, configure the SNMP agent to send SNMP traps to SNMP
management stations, define a syslog host, and compile the Cisco syslog MIB into your SNMP
management station. See the snmp-server and logging commands in the Catalyst 6500 Series Switch
and Cisco 7600 Series Router Firewall Services Module Command Reference for more information.
