Chapter 1 Configuring a Cluster of ASAs
Configuring ASA Clustering
Detailed Steps
Command Purpose
Step 1
(Optional)
mtu cluster bytes
Example:
hostname(config)# mtu cluster 9000
Specifies the same MTU that you configured for the master unit.
Note We suggest setting the MTU to 1600 bytes or greater,
which requires you to enable jumbo frame reservation
before continuing with this procedure. See the “Enabling
Jumbo Frame Support (Supported Models)” section on
page 1-33. Jumbo frame reservation requires a reload of
the ASA.
Step 2
cluster group name
Example:
hostname(config)# cluster group pod1
Identifies the same cluster name that you configured for the
master unit.
Step 3
local-unit unit_name
Example:
hostname(cfg-cluster)# local-unit unit1
Names this member of the cluster with a unique ASCII string from
1 to 38 characters. Each unit must have a unique name. A unit with
a duplicated name will be not be allowed in the cluster.
Step 4
cluster-interface interface_id ip
ip_address mask
Example:
hostname(cfg-cluster)# cluster-interface
port-channel2 ip 192.168.1.2 255.255.255.0
INFO: Non-cluster interface config is
cleared on Port-Channel2
Specifies the same cluster control link interface that you
configured for the master unit.
Specify an IPv4 address for the IP address; IPv6 is not supported
for this interface. This interface cannot have a nameif configured.
For each unit, specify a different IP address on the same network.
Step 5
priority priority_number
Example:
hostname(cfg-cluster)# priority 2
Sets the priority of this unit for master unit elections, between 1
and 100, where 1 is the highest priority. See the “Master Unit
Election” section on page 1-3 for more information.
