Quality of Service (QoS): Managing Bandwidth More Effectively

Differentiated Services Codepoint (DSCP) Mapping

Steps for Configuring Codepoints

1. Determine whether the DSCPs already have priority assignments, which

could indicate use by existing applications. (Also, a DSCP must have a

priority configured before you can assign any QoS classifiers to use it.)

Figure 5-23. Display the Current DSCP Map Configuration

2. Configure the DSCP policies for the codepoints you want to use.

ProCurve(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.
