Chapter 14 Configuring Failover Controlling and Monitoring Failover Entering the following command in the system execution space causes all failover groups to become active: hostname# failover active Disabling Failover To disable failover, enter the following command: hostname(config)# no failover Disabling failover on an Active/Standby pair causes the active and standby state of each unit to be maintained until you restart. For example, the standby unit remains in standby mode so that both units do not start passing traffic. To make the standby unit active (even with failover disabled), see the "Forcing Failover" section on page 14-40. Disabling failover on an Active/Active pair causes the failover groups to remain in the active state on whichever unit they are currently active on, no matter which unit they are configured to prefer. The no failover command should be entered in the system execution space. Disabling Configuration Synchronization Management applications may lose connectivity when upgrading the FWSM with complex configurations. This can result in incomplete configuration files being applied to the standby FWSM. You can disable the automatic configuration synchronization to avoid incomplete configurations being applied to the standby FWSM. You need to disable configuration synchronization when upgrading a software image or changing the configuration on the active FWSM to verify that the configuration files are complete before the configuration is synchronized with the standby FWSM configuration. After you verify that the configuration is complete, reenable configuration synchronization. To disable configuration synchronization, enter the following command: hostname(config)# failover suspend-config-sync To reenable configuration synchronization, use the no form of the this command. Restoring a Failed Unit or Failover Group To restore a failed unit to an unfailed state, enter the following command: hostname(config)# failover reset To restore a failed Active/Active failover group to an unfailed state, enter the following command: hostname(config)# failover reset group group_id Restoring a failed unit or group to an unfailed state does not automatically make it active; restored units or groups remain in the standby state until made active by failover (forced or natural). An exception is a failover group configured with the preempt command. If previously active, a failover group will become active if it is configured with the preempt command and if the unit on which it failed is its preferred unit.
