Configuring an FT Group

This section describes how to configure multiple FT groups on each ACE.
Prerequisites
Before you place an FT group in service, be sure that you have associated one context with the FT group
and that you have properly configured the two peers.

You must configure the same group ID on both peer appliances.
The maximum number of FT groups that you can create is 21 groups (20 user contexts and 1 Admin
context).
Each FT group consists of a maximum of two members (contexts): one active context on one
appliance and one standby context on the peer appliance
Before you can remove a context from an FT group, you must first take the group out of service by
using the no inservice command.
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
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.
