Quality of Service: Managing Bandwidth More Effectively
Globally-Configured QoS

3. Assign the DSCP policies to the selected TCP/UDP port applications and
display the result.
Figure 5-7. Configuring a DSCP Policy for Global TCP/UDP Port Classifiers
The switch applies the DSCP policies in Figure 5-7 to IP packets with the
specified TCP/UDP port applications that are received in the switch. The
switch manages the packets as follows:
HP Switch(config)# qos dscp-map af11 priority 3
HP Switch(config)# qos dscp-map 13 priority 3
HP Switch(config)# qos dscp-map af13 priority 3
HP Switch(config)# write memory
HP Switch(config)# show config
HP Switch configuration:
; J9146 Configuration Editor; Created on release W.14.XX
hostname “Switch”
time daylight-time-rule None
qos dscp-map af11 priority 3
qos dscp-map 13 priority 3
qos dscp-map af13 priority 3
.
.
.
Configure these three codepoints
with non-default priorities.
Show config lists the non
default codepoint settings.
HP Switch(config)# qos udp-port 23 dscp 000111
HP Switch(config)# qos tcp-port 80 dscp 000101
HP Switch(config)# qos tcp-port 914 dscp 000010
HP Switch(config)# qos udp-port range 1001 2000 dscp 000010
TCP/UDP port based priorities
| IP Packet Application |
Protocol | Type Port Apply rule | DSCP Priority
-------- + --------- ----------- ---------- + ------ -----------
UDP | IPV4 23 DSCP | 8 7
TCP | IPV4 80 DSCP | 6 5
TCP | IPV4 914 DSCP | 3 1
UDP | IPV4 1001-2000 DSCP | 3 1
Global TCP/UDP port-

DSCP Policy: DSCP codepoint (3) and 802.1p priority (1)
mapping (Note: DSCP 3 is the decimal equivalent of binary
000010.)
