Displaying Congestion Statistics

To display a count of the packets dropped due to congestion on a port, enter the command:
show ports port_list congestion {no-refresh}
To display a count of the packets dropped due to congestion in the QoS profiles for a port, enter the command:
show ports port_list qosmonitor {congestion} {no-refresh}

Note

On BlackDiamond 8800 c-, and e-series modules, and Summit X440, only one port per slot or module can be monitored at any one time. This restriction does not apply to BlackDiamond 8900 series modules.

On BlackDiamond 8900 xm-series modules and Summit X670 series switches, QP1-4 support one unicast and one multicast queue for each QoS profile. The congestion counters for QP1-4 tally the unicast and multicast traffic for these QoS profiles. Congestion counters for QP5-8 tally only the unicast traffic for these QoS profiles.
