FWSM and Failover setup

Hello:

I am trying to do the failover configuration on the FWSMs (version 3.1(1) and little confused with a statement on the Cisco's configuration guide...

As I understand to configure failover I need to specify the Active and Stanby IP addresses to the failover link using the following command:

"failover int ip if_name ip_addr mask standby ip_addr"

In Cisco's guide there is a note stating the following: "Do not configure an IP address for the failover link or state link if you are going to use stateful failover"

Yes, I do want to use stateful Failover for the Active/Standby setup...

Can someone tell me how do I configure without specifying the IP address to the failover link in a stateful, Active/Standby setup??

Thanks in advance

Re: FWSM and Failover setup

You can use the failover command set to enable a cluster.

On primary unit:

failover lan unit primary

failover lan interface faillink Vlan20

failover key 1234

failover link statelink Vlan21

failover interface ip faillink 1.1.1.1 255.255.255.252 standby 1.1.1.2

failover interface ip statelink 1.1.1.5 255.255.255.252 standby 1.1.1.6

failover

On secondary unit:

failover lan unit secondary

failover lan interface faillink Vlan20

failover key 1234

failover interface ip faillink 1.1.1.1 255.255.255.252 standby 1.1.1.2

failover
