then its auto-negotiation is disabled.

Set Auto-Negotiation Options
The negotiation auto command provides a mode option for conguring an individual port to forced master/ forced slave once auto-
negotiation is enabled.
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.
Example of the negotiation auto Command
