Chapter 1 Configuring a Cluster of ASAs
Command
Step 2
conn-rebalance [frequency seconds]
Example:
hostname(cfg-cluster)# conn-rebalance
frequency 60
Step 3
console-replicate
Example:
hostname(cfg-cluster)# console-replicate
What to Do Next
Add slave units. See the
Examples
The following example configures a management interface, configures a device-local EtherChannel for
the cluster control link, and then enables clustering for the ASA called "unit1," which will become the
master unit because it is added to the cluster first:
ip local pool mgmt 10.1.1.2-10.1.1.9
ipv6 local pool mgmtipv6 2001:DB8::1002/32 8
interface management 0/0
interface tengigabitethernet 0/6
interface tengigabitethernet 0/7
cluster group pod1
Configuring Slave Unit Bootstrap Settings
Perform the following procedures to configure the slave units.

Purpose
Enables connection rebalancing for TCP traffic. This command is
disabled by default. If enabled, ASAs exchange load information
periodically, and offload new connections from more loaded
devices to less loaded devices. The frequency, between 1 and 360
seconds, specifies how often the load information is exchanged.
The default is 5 seconds.
Enables console replication from slave units to the master unit.
This feature is disabled by default. The ASA prints out some
messages directly to the console for certain critical events. If you
enable console replication, slave units send the console messages
to the master unit so you only need to monitor one console port
for the cluster.
