First, determine the current DSCP mapping.

The DSCP value of interest is 46, or 101110 in binary format. We recommend assigning a

priority of 6 for this DSCP value and assigning a policy name to identify that it is for use with

voice. (Note that to simplify the displayed information, the complete mapping table isn’t shown.)

These commands result in the following L3/L2 map settings:

Applying DSCP to Priority QoS Policy Enforcement at the Access Port (optional)

This function is not a requirement of LLDP/LLDP-MED, but may be used where the end device

is not trusted or does not send frames with all the appropriate QoS information. In this case

the ProCurve switch will modify the QoS contents of the outbound packet, based on the ingress

port policy configuration.
