Display Queue Level Packet and Byte Counters
Queue level statistics can be displayed and cleared as described in the following section:
• Displaying queuing class configuration and queue packet and byte counters
• Clearing queue level packet and byte counters
Queue level statistics can be displayed using the command:
show policy-map (interface INTERFACE-NAME|) statistics (class CLASS-NAME|) type queuing
and
show interface (INTERFACE-NAME|) counters queue-stats.
Sample output is shown below:
#show policy-map statistics type queuing

Display Queue Level Instantaneous Transmission Rate
The instantaneous rate at which packets are de queued/transmitted from the queues can be displayed using
show policy-map (interface INTERFACE-NAME|) statistics (class CLASS-NAME|) type queuing (rate (kbps|mbps|gbps)|)
Sample output of the command is shown below:
#show policy-map statistics type queuing rate mbps

Clearing Queue Level Packet and Byte Counters
Queue statistics can be cleared using the command:
clear qos statistics (interface INTERFACE-NAME |) type queuing
and
clear interface counters.
