ExaScale) 10/100/1000 Base-T Ethernet interfaces.
The no negotiation auto command is only available if you first manually set
the speed of a port to 10Mbits or 100Mbits.
The negotiation auto command provides a mode option for configuring an
individual port to forced-master/forced slave after you enable auto-negotiation.
If you do not use the mode option, the default setting is slave. If you do not
configure forced-master or forced-slave on a port, the port negotiates to either a
master or a slave state. Port status is one of the following:
•
•
•
•
•
You can display master/slave settings with the show interfaces command.

(Master/Slave)
Dell(conf-if)#neg auto
Dell(conf-if-autoneg)# ?
