Ether Channeling on two different sfp modules

Hi Experts,

I would like to know if an Ether channel can be created using two different SFP modules i.e using

glc-sx-mm and glc-lh-sm on a switch or on any other device.

Thanks

Abdul Malik.

I didn't tested something like this in production. But having in mind that you can bundle copper and SFP interfaces in etherchannel as long as they have same speed, L2/L3 config etc I think that this is possible...but not 100% sure

Etherchannel does not care about the physical media as long as things like speed, duplex etc. match.

So Dragan is right that it should work fine.

Well I can only recommend global document like this one for example:

That reference doesn't appear to mention, on the 6500s, if you do Etherchannel across line cards with different QoS architectures, Etherchannel may be "unhappy".  There's a no mls qos channel-consistency command to address this.
