Example 150 Configuring new DSCP policies

The following example shows how to configure new DSCP policies on matching packets with the

specified DSCP codepoints.

Policy Name

(Optional)

802.1p PriorityPolicy DSCPReceived DSCP

Level 66000010001100

Level 44000101001101

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-mapcommand). This is not a problem as long as the configured priorities are

acceptable for all applications using the same DSCP.

Also, note that a DSCP codepoint must have a preconfigured 802.1p priority (0 - 7) before

you can use the codepoint to mark matching packets. If a codepoint you want to use shows

No-override in the Priority column of the DSCP Policy table (show qos dscp-map

command), you must first configure a priority for the codepoint before proceeding (qos

dscp-map priority command).

2. Configure the desired policies (codepoint and associated 802.1p priority) in the DSCP table:

Example 151 Configuring DSCP policies in the DSCP table

HP Switch(config)#: qos dscp-map 000010 priority 6 name 'Level 6'

HP Switch(config)#: qos dscp-map 000101 priority 4 name 'Level 4'

HP Switch(config)#: show qos dscp-map

DSCP -> 802.p priority mappings
