Cisco ASA Series CLI Configuration Guide
Chapter 1 Configuring a Cluster of ASAs
Managing ASA Cluster Members
interface remains up using the IP address the unit received from the cluster IP pool. However if you
reload, and the unit is still inactive in the cluster, the management interface is not accessible (because it
then uses the Main IP address, which is the same as the master unit). You must use the console port for
any further configuration.
Prerequisites
For multiple context mode, perform this procedure in the system execution space. If you are not already
in the System configuration mode, enter the
changeto system
command.
Detailed Steps
Leaving the Cluster
If you want to leave the cluster altogether, you need to remove the entire cluster bootstrap configuration.
Because the current configuration on each member is the same (synced from the master unit), leaving
the cluster also means either restoring a pre-clustering configuration from backup, or clearing your
configuration and starting over to avoid IP address conflicts.
Prerequisites
You must use the console port; when you remove the cluster configuration, all interfaces are shut down,
including the management interface and cluster control link. Moreover, you cannot enable or disable
clustering from a remote CLI connection.
Command
Purpose
cluster remove unit
unit_name
Example:
hostname(config)# cluster remove unit ?
Current active units in the cluster:
asa2
hostname(config)# cluster remove unit asa2
WARNING: Clustering will be disabled on
unit asa2. To bring it back
to the cluster please logon to that unit
and re-enable clustering
Removes the unit from the cluster. The bootstrap configuration remains
intact, as well as the last configuration synced from the master unit, so you
can later re-add the unit without losing your configuration. If you enter this
command on a slave unit to remove the master unit, a new master unit is
elected.
To view member names, enter
cluster remove unit ?
, or enter the
show
cluster info
command.
