Quality of Service: Managing Bandwidth More Effectively
Globally-Configured QoS
Example. This example shows how to assign the following DSCP policies to
packets that match the specified TCP and UDP port applications:
1. Determine if the DSCP codepoints that you want to use to mark matching
packets already have an 802.1p priority assigned, which could indicate
use by existing applications (show qos dscp-map command).
Note that a DSCP codepoint must also have a priority configured before
you can use it to mark matching packets.

2. Configure the DSCP policies for the codepoints you want to use.
Syntax: show qos tcp-udp-port-priority
Displays a listing of all TCP and UDP QoS classifiers
currently in the running-config file.
Port Applications DSCP Policies
DSCP Priority
23-UDP 000111 7
80-TCP 000101 5
914-TCP 000010 1
1001-UDP 000010 1
HP Switch(config)# show qos dscp-map
DSCP -> 802.p priority mappings
NOTE: ‘qos type-of-service diff-services’ must be configured
before DSCP is honored on inbound trafic.
