show ports qosmonitor {congestion}

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

Description

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

Syntax Description

port_list Specifies one or more slots and ports.
congestion Specifies the display of packets dropped at ingress 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.

Default

Displays egress packet counts in real-time.

Usage Guidelines

The bottom line in the real-time display shows keys that you can press to change the display. For example, the spacebar toggles the display between egress packet counts and ingress dropped-packet counts.

Note

Note

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

If you specify the no-refresh parameter, the system displays a snapshot of the data at the time you issue 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.

Note

Note

On a V300 bridge port extender (BPE) port, neither show ports port_list qosmonitor {congestion} {no-refresh | refresh} {port-number} nor show ports port_list congestion {no-refresh | refresh}{port-number} increments when there is egress congestion. Instead, you can view egress congestion using show ports {port_list | stack-ports stacking-port-list} rxerrors {no-refresh | refresh} on the ingress port (upstream port in many cases).

Example

The following example shows the egress packet counts for the specified ports:
# show ports 2:1, 3:6 qosmonitor

The next example shows the dropped packet counts for the specified ports:
# show ports 2:1, 3:6 qosmonitor congestion

History

This command was first available in ExtremeXOS 10.1.

You must specify the ports in ExtremeXOS 11.0.

The no-refresh keyword was added in ExtremeXOS 11.3.

The congestion keyword was added in ExtremeXOS 12.2, and the toggling functionality was modified to switch between egress packets and dropped packets.

The refresh keyword was added in ExtremeXOS 16.1.

Platform Availability

This command is available on all Universal switches supported in this document.
