Assigning DSCP policies to packets matching specified TCP and UDP port

applications (Example)

1. Determine whether 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: A DSCP codepoint must also have a priority configured before you can use it to

mark matching packets.

Example 146 Viewing the current DSCP-map configuration

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.
