Controlling and Monitoring Failover Chapter 14 Configuring Failover Monitoring Failover When a failover occurs, both FWSMs send out system log messages. This section includes the following topics: • Failover System Log Messages, page 14-42 • Debug Messages, page 14-42 • SNMP, page 14-42 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. Note During switchover, failover will logically shut down and then bring up interfaces, generating system log 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. Note Because debugging output is assigned high priority in the CPU process, it can drastically affect system 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. 14-42 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
