Cluster-XL Information Legacy Mode

[wiz4rd]

Hello guys,

I Need to know if under Legacy mode when an fault occour the mac-address is the same on the other memeber.

If I have two nodes ( pivot and standby member) and the pivot goes down, the other memeber will have the same Mac address ?

Is important for me understand well because if I change the pivot member the mac is different and the arp cache needs 10 minute to refresh.

Thank for any reply :)

I dont know but I if I recall the Cluster XL whitepaper downloadable from checkpoint goes into some detail on things like that.

Im not a great MAC address etc expert so maybe misunderstanding you but on page 186 of the cluster xl guide for NGX R62 it says

"In Legacy Mode the cluster members share identical IP and MAC addresses, so that
the active cluster member receives from a hub or switch all the packets that were
sent to the cluster IP address."

Thanks

Hi Birmingham,

I have NGX R60 but I think that is the same for documentation, the problem is when the pivot node goes down the mac address is of the other node (non pivot) and is a big problem for all session that needs to know the new mac-address. I will try to reboot the node.

Stay tuned

Thank you :)

Based on the quote from the white paper the mac address should be the same for both members. Are you sure you are not looking at the mac address for the local box ip and mac not the cluster ip & mac it is broadcasting for the cluster which according to the white paper should be the same on both boxes.

I always test failover by putting lots of stuff in a massive zip file and ftping it across the cluster, rebooting the members as it passes through.
