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)# ?
end Exit from configuration mode
exit Exit from autoneg configuration mode
mode Specify autoneg mode
no Negate a command or set its defaults
show Show autoneg configuration information
Dell(conf-if-gi-1/1-autoneg)#
mode ?
forced-master Force port to master mode
forced-slave Force port to slave mode
Dell(conf-if-gi-1/1-autoneg)#
For details about the speed, duplex, and negotiation auto commands, refer to the Interfaces chapter of
the
Dell Networking OS Command Reference Guide.
