Setting Auto-Negotiation Options
The negotiation auto command provides a mode option for conguring an individual port to forced master/forced slave after
you enable auto-negotiation.
CAUTION: Ensure that only one end of the node is congured as forced-master and the other is congured as forced-
slave. If both are congured the same (that is, both as forced-master or both as forced-slave), the show interface
command aps between an auto-neg-error and forced-master/slave states.
