Example of the show interfaces status Command to View Link Status
NOTE: The show interfaces status command displays link status, but not administrative
status. For both link and administrative status, use the
show ip interface [interface |
brief | linecard slot-number] [configuration] command.

In the previous example, several ports display “Auto” in the Speed field, including port 0/1. In the following
example, the speed of port 0/1 is set to 100Mb and then its auto-negotiation is disabled.
Dell#configure
Dell(config)#interface tengig 0/1
Dell(conf-if-te-0/1)#speed 100

Set Auto-Negotiation Options
The negotiation auto command provides a mode option for configuring an individual port to forced
master/ forced slave once auto-negotiation is enabled.
CAUTION: Ensure that only one end of the node is configured as forced-master and the other is
configured as forced-slave. If both are configured the same (that is, both as forced-master or
both as forced-slave), the show interface command flaps between an auto-neg-error and
forced-master/slave states.
