L3 Etherchannel between 2911 and Stack?

[devils_advocate]

Hello

The 2911 has 3x L3 Gigabit interfaces so my plan is to setup a Layer 3 etherchannel using two of them and connect it to a 3750x stack....will this work?

I know the config, I just wasn't 100% certain the 2911 will let me use the built in GE ports for a Layer 3 etherchannel?

We don't need 2GB of througput but would like the resiliency against a cable failure.

Thanks

I don't believe you'll have an issue. I have 2911s and have the option to configure them:

You'll need to make sure that on the switch you configure "channel-group mode on". The routers do not support pagp/lacp protocols.

HTH,
John

Thanks John, I thought it would work but I am putting together a design and didn't have any 2911 routers to test. We have one on order and will test it before it works. Previously here they had a single uplink cable to the router so I want to at least mitigate against a cable issue or switch failure as its a stack anyway.

Thanks
