Quality of Service (QoS): Managing Bandwidth More Effectively 
Using QoS Classifiers To Configure Quality of Service for Outbound Traffic 
3.  Assign the DSCP policies to the selected source-ports and display the 
result. 
Figure 8-35.  The Completed Source-Port DSCP-Priority Configuration 
Radius Override Field.  During a client session authenticated by a RADIUS 
server, the server can imose a port priority that applies only to that client 
session. Refer to the RADIUS chapter in the Access Security Guide for your 
switch (January 2005 or later). 
Differentiated Services Codepoint (DSCP) Mapping 
The DSCP Policy Table associates an 802.1p priority with a specific ToS byte 
codepoint in an IPv4 packet. This enables you to set a LAN policy that operates 
independently of 802.1Q VLAN-tagging. 
In the default state, most of the 64 codepoints do not assign an 802.1p priority, 
as indicated by No-override in table 8-14 on page 8-63. 
You can use the following command to list the current DSCP Policy table, 
change the codepoint priority assignments, and assign optional names to the 
codepoints.
