Quality of Service: Managing Bandwidth More Effectively

Differentiated Services Codepoint (DSCP) Mapping

2. Change each QoS configuration by assigning a different DSCP policy or a

different 802.1p priority, or by removing the currently configured DSCP

policy and restore the default No-override setting; for example:

a. Delete the current DSCP policy used to mark matching packets for a

global IP-device policy (no qos device-priority command) and reset the

default priority mapping to No-override.

b. Create a new DSCP policy to use when you reconfigure QoS policies

to use the new codepoint-priority mapping.

c. Configure a global QoS source-port policy to mark matching packets

with the new DSCP policy.

d. Assign the global QoS policy that matches udp-port 1260 packets to a

different 802.1p priority.

3. Reconfigure the desired priority for the 000001 codepoint.

HP Switch(config)# qos dscp-map 000001 priority 4

4. Reconfigure QoS policies with the original codepoint (000001) to mark

packets with the new DSCP-priority mapping, or leave QoS policies as

currently configured from Step 2.

a) HP Switch(config)# no qos device-priority 10.26.50.104

b) HP Switch(config)# qos dscp-map 000100 priority 6

c) HP Switch(config)# int 3 qos dscp 000100

d) HP Switch(config)# qos udp-port 1260 priority 2
