Configuring Asa Clustering - Cisco ASA Series Cli Configuration Manual

Configuring ASA Clustering

Cabling the Cluster Units and Configuring Upstream and Downstream
Equipment
Before configuring clustering, cable the cluster control link network, management network, and data
networks.
Note
At a minimum, an active cluster control link network is required before you configure the units to join
the cluster.
You should also configure the upstream and downstream equipment. For example, if you use
EtherChannels, then you should configure the upstream and downstream equipment for the
EtherChannels.
Examples
Note
This example uses EtherChannels for load-balancing. If you are using PBR or ECMP, your switch
configuration will differ.
For example on each of 4 ASA 5585-Xs, you want to use:
•
•
•
You have one switch for both the inside and outside networks.

2 Ten Gigabit Ethernet interfaces in a device-local EtherChannel for the cluster control link.
2 Ten Gigabit Ethernet interfaces in a Spanned EtherChannel for the inside and outside network;
each interface is a VLAN subinterface of the EtherChannel. Using subinterfaces lets both inside and
outside interfaces take advantage of the benefits of an EtherChannel.
1 Management interface.
