Displaying flow-control status

The show interface command with the appropriate parameters displays configuration, operation, and negotiation status where applicable.

For example, on a FastIron Stackable device, issuing the command for 10/100/1000M port 1/1/21 displays the following output.

device# show interfaces ethernet 1/1/21

• If flow control negotiation is enabled (and a neighbor advertises "Pause-Capable"), the display shows:

Flow Control is config enabled, oper enabled, negotiation enabled

• If flow control is enabled, and flow control negotiation is disabled, the display shows:

Flow Control is config enabled, oper enabled, negotiation disabled

• If flow control is disabled, the display shows:
