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:
Display queue level statistics using the commands:
show policy-map, show policy-map interface, and show interface IFNAME 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
