The Cisco ASA has a rich set of show and debug commands that are useful to monitor the status of the standby Cisco ASA. These commands are particularly important in isolating a problem if something behaves unexpectedly. The necessary show and debug commands that are used to manage Active/Standby and Active/Active failover in the Cisco ASA are discussed in this section. Deployment Scenario 1 is used for references in this section.
Once the primary Cisco ASA is configured for failover, the first thing to check is to verify that the Cisco ASA is recognizing failover as enabled. The status of an Cisco ASA’s failover can be checked by using the show failover command, as shown in Example 11-31.
