Configuring Redundancy Chapter 7 Configuring Redundant ACE Appliances Note The ACE does not perform bulk config synchronization (sync) on the peer priority command value in the FT group associated with the Admin context to the peer. Therefore, you may observe a peer priority value in the running-configuration file that is different from the actual operating value. For information on bulk config sync, see the "Synchronizing Redundant Configurations" section. For example, to configure the priority of the FT group member on the remote standby member, enter: host1/Admin(config-ft-group)# peer priority 50 To restore the default priority of 100, enter: host1/Admin(config-ft-group)# no peer priority Configuring Preemption Preemption ensures that the group member with the higher priority always asserts itself and becomes the active member. By default, preemption is enabled. To configure preemption after it has been disabled, use the preempt command in FT group configuration mode. The syntax of this command is: preempt For example, enter: host1/Admin(config-ft-group)# preempt To disable preemption, enter: host1/Admin(config-ft-group)# no preempt Note If you disable preemption by using the no preempt command and a member with a higher priority is found after the other member has become active, the electing member becomes the standby member even though it has a higher priority. 7-22 Cisco 4700 Series Application Control Engine Appliance Administration Guide OL-11157-01
