Set Auto-Negotiation Options

The negotiation auto command provides a mode option for configuring an individual port to forced

master/ forced slave once auto-negotiation is enabled.

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.
