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.
