Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure Quality of Service for Outbound Traffic
1. Identify the IP address to use as a classifier for assigning a DSCP policy.
2. Determine the DSCP policy for packets carrying the selected IP address:
a. Determine the DSCP you want to assign to the selected packets. (This
codepoint will be used to overwrite the DSCP carried in packets
received from upstream devices.)
b. Determine the 802.1p priority you want to assign to the DSCP.
3. Configure the DSCP policy by using dscp-map to configure the priority to
the codepoint you selected in step 2a. (For details, refer to “Differentiated
Services Codepoint (DSCP) Mapping” on page 5-51.)
4. Configure the switch to assign the DSCP policy to packets with the
specified IP address.
For example, suppose you wanted to assign these DSCP policies to the packets
identified by the indicated IP addresses:
Assign the DSCP policies to the selected device IP addresses and display the
result.
Syntax: qos device-priority < ip-address > dscp < codepoint >
Assigns a DSCP policy to packets carrying the specified IP
address, and overwrites the DSCP in these packets with the
assigned
< codepoint > value. This policy includes an 802.1p
priority and determines the packet’s queue in the outbound
port to which it is sent. If the packet leaves the switch on a
tagged port, it carries the 802.1p priority with it to the next
downstream device. (Default:
No-override)
no qos device-priority < ip-address >
Deletes the specified IP address as a QoS classifier.
