Configuring LAN QoS

LAN QoS specifies priority values that can be used to differentiate traffic and give
preference to higher-priority traffic, such as telephone calls. Refer to the following
topics:
• Configuring LAN Queue Settings, page 166
• Configuring LAN QoS Classification Methods, page 166
• Mapping CoS to LAN Queue, page 167
• Mapping DSCP to LAN Queue, page 167
• Configuring Default CoS, page 168
Add a QoS class rule with the following settings:
• Class: Choose the traffic class called
"voice-inbound-class."
• DSCP Marking: Choose the DSCP tag value
(such as 46) for the inbound voice traffic
depending on the QoS settings on your voice
switch.
• CoS Marking: Choose the CoS tag value (such
as 6) for the inbound voice traffic depending on
the QoS settings on your voice switch.
