Usage Information
This command is supported on C-Series, S-Series, and E-Series (TeraScale and ExaScale) 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 conguring 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 congure 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
