In the previous example, several ports display “Auto” in the Speed eld. In the following example, the speed of port 1/1 is set to 100Mb and
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
DellEMC(conf)# int gigabitethernet 1/1
DellEMC(conf-if-gi-1/1)#neg auto
DellEMC(conf-if-gi-1/1-autoneg)# ?
end Exit from configuration mode
exit Exit from autoneg configuration mode
