Syntax:

show qos device-priority

Displays a listing of all QoS VLAN-ID classifiers currently in the running-config file.

Example 155 Assigning DSCP policies to packets

Assigning DSCP policies (codepoint and associated 802.1p priority) to packets with the specified

VLAN IDs:

PriorityDSCPVLAN-ID

700011140

500010130

100001020

10000101

1. Determine if the DSCP codepoints that you want to use to mark matching packets already

have an 802.1p priority assigned, which could indicate use by existing applications (show

qos dscp-mapcommand). This is not a problem as long as the configured priorities are

acceptable for all applications using the same DSCP.

A DSCP codepoint must also have a priority configured before you can use it to mark matching

packets.

2. Configure the priorities for the DSCPs.
