Usage Information
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:
Forced-master
Force-slave
Master
Slave
Auto-neg Error — typically indicates that both ends of the node are configured with forced-master or forced-
slave.
CAUTION: Ensure that one end of your node is configured as forced-master and one is configured as
forced-slave. If both are configured the same (that is, forced-master or forced-slave), the show
interfaces command flaps between an auto-neg-error and forced-master/slave states.
You can display master/slave settings with the
show interfaces command.
