Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure Quality of Service for Outbound Traffic
Radius Override Field. During a client session authenticated by a RADIUS
server, the server can impose 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 8-65.
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.
Syntax: show qos dscp-map
Displays the DSCP Policy Table.
qos dscp-map < codepoint > priority < 0 - 7 > [name < ascii-string >]
Configures an 802.1p priority for the specified codepoint
and, optionally, an identifying (policy) name.
no qos dscp-map < codepoint >
Reconfigures the 802.1p priority for <codepoint> to No-over-
ride. Also deletes the codepoint policy name, if configured.
no qos dscp-map < codepoint > name
Deletes only the policy name, if configured, for < codepoint >.
