Usage
Information
This command is supported on 10/100/1000 Base-T Ethernet interfaces.
You can use the 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.
NOTE: The mode option is not available on non-10/100/1000 Base-T Ethernet line cards.
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
