port aggregation on different switches?

Hello all :)

I got a server PC with two fast ethernet NICs (NICS do support port aggregation)

I know you can connect two 100 Mbps ports of server to two fast ethernet ports of a switch, this way you get one 200 Mbps link. If one of the ports or one of the links fail, other link keeps working.

this is a vey nice redundancy.

My question is;

is it possible to bundle two fast ethernet ports of server to two different switches? (first ethernet port of PC to switch 1 and second ethernet port of PC to switch 2. switch 1 and switch 2 are connected each other with an uplink)

if possible, what is the CLI command for that?

thank you very much for helping.

Re: port aggregation on different switches?

Hello,

AFAIK, and unless something has changed very recently, the only way to link two (or more) switches together in a single Etherchannel is in a stack configuration.

Nortel appears to have a feature called Split MultiLink Trunking, which does multichassis trunking, you might want to have a look at the document below:

Layer 2 Trunking Availability Strategies using SMLT and DMLT
