Etherchannel Question

[BVI]

I would like to connect two 6509's with a 4 port etherchannel between them. In order to provide some redundancy I don't want to have all four ports on a single module. I want to use two ports on one module and two ports on another module to create the channel.

6509A - 3/1-2 ======= 3/1-2 - 6509B
4/1-2 ======= 4/1-2

Documentation states that this should not be a problem:

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/ios127xe/78_10404.htm

All Ethernet interfaces on all modules, including those on a standby supervisor engine, support EtherChannel (maximum of eight interfaces) with no requirement that interfaces be contiguous or on the same module.

Has anyone tried this? Does it work well? Is configuration straight forward?

Thanks

Yup, I've done it and it works fine. (4 gigabits on 2 blades) Just make sure all the ports are configured the same (vlan, stp, priority, etc). One thing to remember is that the aggregate can only be in a multiple of two. If you have 4 and 1 goes it will back down to using 2.

Thank you for the quick response and the tips. I'm going to be running a trunk on this channel.
