Usage Information
This command is supported on 10/100/1000 Base-T Ethernet interfaces.
You can use the negotiation auto command on the 10G ports on the device.
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.
