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.
Example of the negotiation auto Command
DellEMC(conf)# int tengigabitethernet 1/1
DellEMC(conf-if-te-1/1)#neg auto
DellEMC(conf-if-te-1/1-autoneg)# ?
end Exit from configuration mode
exit Exit from autoneg configuration mode
