Failover System Messages
The security appliance issues a number of system messages related to failover at priority level 2, which
indicates a critical condition. To view these messages, see the Cisco Security Appliance Logging
Configuration and System Log Messages to enable logging and to see descriptions of the system
messages.
Note During switchover, failover logically shuts down and then bring up interfaces, generating syslog 411001
and 411002 messages. This is normal activity.
Debug Messages
To see debug messages, enter the debug fover command. See the Cisco Security Appliance 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 Cisco Security Appliance
Command Reference for more information.
