Shalom,

Few ways.

A script that does an ifconfig command

ifconfig lan0:0 ipaaddress netmask up

Of course it needs to make sure the ip address is not active on the second node, so its not an easy script.

Serviceguard - a pay for add in program that creates a high availability cluster including the ability to set up a virtual ip address.

Hello Taifur,

In this scenario you will need an additional product called APA - auto port aggregation.

You can configure APA in LAN_MONITOR mode - when one lan fail, another will take the traffic.
