show ports port_list flowcontrol {rx-pauses} {tx-pauses} {no-refresh | refresh}

Description

Syntax Description

rx-pauses Displays pause control frames received.
tx-pauses Displays pause control frames transmitted.
no-refresh Specifies a static snapshot of data.
refresh Specifies a continuous refresh of output.

Default

By default, the pause control frames received are displayed.

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].

Example

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

# show ports 1,5,9 flow-control
