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 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
• 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.
