Usage Information
This command is supported on 10/100/1000 Base-T Ethernet interfaces.
The no negotiation auto command is only available if you rst manually set the speed of a port to 10Mbits
or 100Mbits.
The negotiation auto command provides a mode option for conguring an individual port to forced-master/
forced slave after you enable auto-negotiation.
NOTE: The mode option is not available on non-10/100/1000 Base-T systems.
If you do not use the mode option, the default setting is slave. If you do not congure 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:
Forced-master
Force-slave
Master
Slave
Auto-neg Error — typically indicates that both ends of the node are congured with forced-master or forced-
slave.
CAUTION: Ensure that one end of your node is congured as forced-master and one is congured as
forced-slave. If both are congured the same (that is, forced-master or forced-slave), the show
interfaces command aps between an auto-neg-error and forced-master/slave states.
You can display master/slave settings with the show interfaces command.
