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