In the previous example, several ports display “Auto” in the Speed field. In the following example, the speed of port 1/1 is set to
100Mb and then its auto-negotiation is disabled.
Dell#configure
Dell(config)#interface gig 1/1
Dell(conf-if-gi-1/1)#speed 100
Dell(conf-if-gi-1/1)#duplex full
Dell(conf-if-gi-1/1)#no negotiation auto
Dell(conf-if-gi-1/1)#show config

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
Dell(conf)# int gigabitethernet 1/1
Dell(conf-if-gi-1/1)#neg auto
Dell(conf-if-gi-1/1-autoneg)# ?
