I have (2)6509's with a Sup720 and a new 6748-TX blade. The Sup720 has SFP Gig ports. The two switches reside within 5 feet of each other.
I had already connected the two 6509's together using one of the SFP ports in each switch. I would like to migrate this connection from the SFP port on the Sup720 to the Copper Gig TX port on the 6748-TX.
My question is: Is it possible for me to create a port channel with the existing fiber connection together with the new copper connection? Are there any concerns with doing this?
Thank you.
