show ports stack-ports qosmonitor congestion

show ports stack-ports stack_port_list qosmonitor congestion {no-refresh | refresh} {port-number}

Description

Displays packet counts or dropped-traffic counts for each QoS profile on the specified stacking ports.

Syntax Description


`stack_port_list`	Specifies one or more stacking ports.
congestion	Specifies the display of packets dropped due to port congestion.
no-refresh	Specifies a static snapshot of data instead of the default dynamic display.
refresh	Specifies a continuous refresh of output.
port-number	Displays port number instead of display string in the output of the command.

Default

Displays packet counts in real-time.

If you do not specify a port number or range of ports, traffic counts appear for all ports.

Usage Guidelines

The bottom line in the real-time display shows keys that you can press to change the display. For example, the space bar changes the display from packet counts and dropped-packet counts.

Note

This command does not work properly if another CLI session is displaying congestion statistics in real time.

If you specify the no-refresh option, you see a snapshot of the data at the time you issued the command.

The dropped packet display is limited to the 8 most-significant digits.

When you display the packet counts for a port, this action configures the hardware to monitor that port. If the switch was previously configured to monitor a different port, the counters are reset for the new port. If the selected port is the last port displayed on the switch, the counters are not reset.

Example

The following example shows the dropped packet counts for ports 2:1 and 3:6:

# show ports 2:1, 3:6 qosmonitor congestion
