Etherchannel questions

[Russell Pearson]

Hey there,

So I have a front switch stack with (9) 3750 switches in it and and back stack with (5) 3750 switches.

I have a fiber connection between the two.

I want to make this a redundant connection and make sure it's not a bottleneck.

I know I can configure an etherchannel, but can I do this while connecting the stacks to different switches in the stack for redundancy?

Thanks in advance.

Hi,

but can I do this while connecting the stacks to different switches in the stack for redundancy?

Yes, you can do that. It is called Cross-Stack EtherChannel. See the following documents for more information:
