Displays the pause control frames received or transmitted.

Usage Guidelines

If you do not specify a port number or range of ports, the system displays information for all ports.

If you specify the no-refresh parameter, the system displays a snapshot of the data at the time you issue the command. If you do not specify the no-refresh option, the display refreshes until you press [ESC].


The following example displays the flow control for ports 1, 5, and 9.

# show ports 1,5,9 flow-control
