3350 T12 Port Redundancy

I have a 3550 enh. SW Image Switch wit 2 GB LX GBICS.

I want to use them to connect to the same remote switch. In case of Link break of one fiber the other Port needs to be activated automatically.

The remote Switch is NOT a Cisco Device.

Any ideas how to treat this problem ?

Thanks in advance

Re: 3350 T12 Port Redundancy

If it's running the IOS switch code and not the CatOS code you might try the Backup command in the interface config. you can specify a backup interface that will become active if that link becomes unactive. Or if both switches support trunking you could setup a trunk between them.

The Catalyst 3550 can be used as Layer2/Layer3 device. I don't know how you are setting the switch up, but I am assuming that it is L2--all ports on the switch belong to the same VLAN. In that case, if the other switch (non-Cisco) supports Spanning-tree standard, then by just connecting the switches together and let Spanning-tree figures out which path to block.
