Displays egress packet counts or dropped-traffic counts for each QoS profile on the specified ports.
| 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. |
Displays egress packet counts in real-time.
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
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
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).# show ports 2:1, 3:6 qosmonitor Qos Monitor Req Summary Thu Mar 2 10:58:23 2006 Port QP1 QP2 QP3 QP4 QP5 QP6 QP7 QP8 Pkt Pkt Pkt Pkt Pkt Pkt Pkt Pkt Xmts Xmts Xmts Xmts Xmts Xmts Xmts Xmts ================================================================================ 2:1 0 0 0 0 0 0 0 0 3:6 0 0 0 0 0 0 0 0 ================================================================================ > indicates Port Display Name truncated past 8 characters Spacebar->Toggle screen 0->Clear counters U->Page up D->Page down ESC->exit

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.
This command is available on ExtremeSwitching 5320, 5420, 5520, and 5720 series switches.
