I have a NetApp device that has two controllers (basically 4 ethernet ports) the two ports on the top controller are bonded and the two on the bottom are bonded.

For sake of argument the network setup looks similar to:

Controller 1:

E0a -> E0b 192.168.1.101

Controller 2:

E0a -> E0b 192.168.1.102

The switches are stacked so controller 1 goes to port 15 on two switches and controller 2 goes to port 25 on both switches.

The way the NetApp works is it wants to do active/active on both ports of each controller and in the event that controller 1 fails completely (both ports go out hardware failure) the NetApp can pick up the 192.168.1.101 traffic on controller 2 (they are partners and talk over fiber interconnects).

The question is how can I get the switch to allow this?

I am thinking that I need to setup a LAG with all four ports on the two switches (port 15 and 25 on both into one group).

Does anyone out there have a similar setup or ideas on this?

 

Thanks,

Matt
