Are there any design or architectural considerations to make when mixing fiber and copper gigabitethernet ports in a port channel? Is this practice discouraged and, if so, why?
Moreover, I am wondering what the qualitative difference is between fiber and copper for inter-switch trunks for switches that are sitting 10 feet away from each other....? The gigE standard for Cat6e is about 100 meters, so given a distance of less than that between two switches that need to be trunked up, why use fiber and pay the higher cost of fiber jumpers and modules?
By the way, sorry for posting so many questions lately. I am involved in a network reference architecture project and such isses arise all the time. I really do the ned the expertise and insight of seasoned professionals.
1) Cost. (You're wasting money on a fibre link when it's not needed)
2) Standards. (If you're mixing then you obviously don't care about link quality. What kind of fibre is it? OM1/2/3/OS1? Is the copper CAT5/5e/6/7?)
In a small company you can get away with anything if it works - but try defining a Data Center cabling standard which is distibuted to your cabling contractors which says you can mix and match anything you like for an etherchannel as long as it works...
