Configuration Example of Redundancy

This section shows an example redundancy configuration and illustrates a running-configuration that
defines fault tolerance (FT) for a single ACE appliance operating in a redundancy configuration. You
must configure a maximum of two ACE appliances (peers) for redundancy to fail over from the active
appliance to the standby appliance.
All FT parameters are configured in the Admin context.
Note
This configuration addresses the following redundancy components:
•
•
•
•
The redundancy configuration appears in bold in the example.

Purpose
The keywords are as follows:
cfg_cntlr—Clears the Configuration Controller debug log
•
ha_dp_mgr—Clears the HA (redundancy) dataplane manager debug log
•
ha_mgr—Clears the HA (redundancy) manager debug log
•
A dedicated FT VLAN for communication between the members of an FT group. You must
configure this same VLAN on both peer appliances.
An FT peer definition.
An FT group that is associated with the Admin context.
A critical tracking and failure detection process for an interface.
