Configuring ASA Clustering
Detailed Steps
Command Purpose
Step 1
(IPv4)
ip local pool poolname
first-address—last-address [mask mask]
(IPv6)
ipv6 local pool poolname
ipv6-address/prefix-length
number_of_addresses
Example:
hostname(config)# ip local pool ins
192.168.1.2-192.168.1.9
hostname(config-if)# ipv6 local pool
insipv6 2001:DB8::1002/32 8
Configures a pool of Local IP addresses (IPv4 and/or IPv6), one
of which will be assigned to each cluster unit for the interface.
Include at least as many addresses as there are units in the cluster.
If you plan to expand the cluster, include additional addresses.
The Main cluster IP address that belongs to the current master unit
is not a part of this pool; be sure to reserve an IP address on the
same network for the Main cluster IP address.
You cannot determine the exact Local address assigned to each
unit in advance; to see the address used on each unit, enter the
show ip[v6] local pool poolname command. Each cluster member
is assigned a member ID when it joins the cluster. The ID
determines the Local IP used from the pool.
Step 2
interface interface_id
Example:
hostname(config)# interface
tengigabitethernet 0/8
Enters interface configuration mode.
Step 3
(Management interface only)
management-only
Example:
hostname(config-if)# management-only
Sets an interface to management-only mode so that it does not
pass through traffic.
By default, Management type interfaces are configured as
management-only. In transparent mode, this command is always
enabled for a Management type interface.
This setting is required if the cluster interface mode is Spanned.
Step 4
nameif name
Example:
hostname(config-if)# nameif inside
Names the interface.
The name is a text string up to 48 characters, and is not
case-sensitive. You can change the name by reentering this
command with a new value.
Step 5
(IPv4)
ip address ip_address [mask] cluster-pool
poolname
(IPv6)
ipv6 address ipv6-address/prefix-length
cluster-pool poolname
Example:
hostname(config-if)# ip address
192.168.1.1 255.255.255.0 cluster-pool ins
hostname(config-if)# ipv6 address
2001:DB8::1002/32 cluster-pool insipv6
Sets the Main cluster IP address and identifies the cluster pool.
This IP address must be on the same network as the cluster pool
addresses, but not be part of the pool. You can configure an IPv4
and/or an IPv6 address.
DHCP, PPPoE, and IPv6 autoconfiguration are not supported; you
must manually configure the IP addresses.
