HP 7102dl - ProCurve Secure Router Configuration Manual page 363

It designates the order in which the ProCurve Secure Router matches
traffic to these entries—The ProCurve Secure Router searches QoS
entries with the lowest number first. Sequence numbers are only signifi-
cant within the named map; QoS maps with different names can have
entries with the same sequence number.
Each entry contains match commands and one or more actions. The match
command determines the criteria for the class, low-latency queue, or marked
packets.
This criteria can be based on:
IP precedence or DiffServ value
source and/or destination IP address and port (using an extended ACL)
destination UTP protocol port
bridged traffic
If you specify more than one match command for the QoS map, then traffic
must match at least one of the criteria.
The action determines whether the router places matching traffic in a CBWFQ
class or low-latency queue. The action can also mark the traffic with a ToS
value.
After you create a QoS map, you must assign it to an interface to enable the
class, low-latency queue, or packet marking.
