Verifying and Monitoring Priority Queues
The Cisco 10000 series router collects statistical information about the current priority queue length, and
the number of packets and bytes transmitted and dropped.
To verify and monitor the contents of the priority queue (such as queue depth and the first packet
queued), and to verify the configuration of multi-level priority queues and to display statistical
information for each priority level, enter any of the following commands in privileged EXEC mode:
Command
Router# show policy-map policy-map-name
Router# show policy-map interface interface
Verification Examples for Priority Queues
This section provides the following verification examples:

Verifying a Priority Queue: Example
Example 8-3
Business class is the priority queue and is policed at 8000 bps with committed bursts of 5000 bytes and
extended bursts of 6000 bytes.
Example 8-3
Router# show policy-map interface atm 3/0/0.532
ATM3/0/0.532: VC 5/32 -
Service-policy output: Gold
OL-7433-09
Verifying a Priority Queue: Example, page 8-11
Verifying Multi-Level Priority Queues: Example, page 8-12
shows sample output from the show policy-map interface command. In the example, the
Verifying Priority Queuing
Class-map: Business (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: ip precedence 4
Output queue: 0/512; 0/0 packets/bytes output, 0/0 drops
Police:
8000 bps, 5000 limit, 6000 extended limit
conformed 0 packets, 0 bytes; action: transmit
exceeded 0 packets, 0 bytes; action: drop
violated 0 packets, 0 bytes; action: drop
Absolute priority
Class-map: Non-Business (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: ip precedence 3
Purpose
Displays the contents of the policy map you specify, including the
priority class.
Displays statistical and configuration information about the input
and output policies attached to the interface you specify, and
indicates any dropped packets or bytes for the priority class.
