Step 2
ft group group_id
Example:
host1/Admin(config) ft group 1
host1/Admin(config-ft-group)#
Step 3
no preempt
Example:
host1/Admin(config-ft-group)# no preempt
Step 4
Ctrl-z
Example:
host1/Admin(config-ft-group)# Ctrl-z
host1/Admin#
Step 5
ft switchover [all [force] | force |
[ group_id [force]]]

(yes/no)? [no] yes

Synchronizing Redundant Configurations

This section describes how to synchronize redundant configurations. To ensure that the running
configurations on both the active and the standby contexts of an FT group are identical, the ACE
automatically synchronizes the running configurations between the two contexts. After the active
context has accepted either a new configuration or modifications to an existing configuration, the ACE
automatically applies the new configuration or configuration changes to the standby context and disables
configuration mode in the standby context.
The ACE supports the following two types of configuration synchronizations:
•
•
OL-20823-01
Bulk config sync—Synchronizes the entire active context configuration to the standby context when
the peer comes up or when autosynchronization is enabled
Dynamic config sync—Synchronizes the configuration applied to the active context to the standby
context if the peer is already up
Cisco 4700 Series Application Control Engine Appliance Administration Guide
Purpose
Enters global configuration mode.
Enters the FT group configuration mode.
Disables preemption.
Returns to the Exec mode prompt.
Causes a switchover.
The keywords, arguments, and options are:
all—(Optional) Causes a switchover of all FT groups
•
configured in the ACE simultaneously. This keyword is
available in the Admin context only.
force—(Optional) Causes a switchover while ignoring the
•
state of the standby member. Use this option only when the
FT VLAN is down. This keyword is available in the Admin
context only.
group_id—(Optional) FT group that you want to switch over.
•
Enter the ID of an existing FT group as an integer from 1 to
255. This argument is available in the Admin context only.
