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
