[c-nsp] The myths of autonegotiate vs forced

[Jim Getker (getker)]

We just didn't see a need to support 10 and 100 individually.  There is no standard regarding this as far as I know.

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?)
