5406 Multiple Trunks

5406 Multiple Trunks

I have 2 5406's connected to each other via a 4gb trunk called Trk1. This trunk is tagged on all my VLANs.

I have an ISCSI storage array and that traffic is init's own VLAN (VLAN5). It's been suggested by my storage vendor that the storage vlan should be using it's own trunk and not Trk1. I've created a new 8gb Trunk (Trk3) and have tagged it on VLAN5 and also removed Trk1 from VLAN5. I've tested pinging from 1 core to the other, but is not working.

Is this a supported configuration? If yes any suggestions on what may be wrong?

Re: 5406 Multiple Trunks

you can do this, but need to have mstp. with stp or rstp one of the trunks is in blocking.
