Its an ASIC thing. What you can configure the port to do is only negotiate at a subset of speeds it is capable of. I think this is actually a feature of the ASIC, not software per se.
I'm guessing. ________________________________ From: Peter Rathlev <[email protected]> To: Jim Getker (getker) <[email protected]> Cc: [email protected] Sent: Fri, August 20, 2010 3:36:27 PM Subject: Re: [c-nsp] The myths of autonegotiate vs forced On Fri, 2010-08-20 at 14:58 -0500, Jim Getker (getker) wrote: > The 6K gigabit copper ports support speed auto 10 100. Hm... it actually does support "speed auto 10 100", but "speed auto 100" returns an error (WS-X6748-GE-TX): Switch(config)#int gi1/1 Switch(config-if)#speed auto 100 Speed autonegotiation subset is not supported on this interface Switch(config-if)#speed auto 10 100 Switch(config-if)# This confuses a novice like me. Maybe the output could be adjusted a little? :-) (And why support "10/100 only" and not "100 only" anyway? Standards compliance of some kind?) -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
