Marking Packets With A Tos Value; Creating A Qos Map Entry - HP 7102dl - ProCurve Secure Router Configuration Manual

Marking Packets with a ToS value

The ProCurve Secure Router can mark the ToS field of packets it forwards
with an IP precedence or DiffServ value. These ToS values grant packets
different types of service according to configurations in the connecting net-
work. You should negotiate with your service provider or other connecting
network which packets will be marked with which values and what level of
service these values entail.
You can also mark packets with IP precedence values for implementing WFQ
on the router. (See "Configuring WFQ" on page 8-14.)
However, you cannot assign a packet a ToS value in one map entry and then
match that ToS value to a low-latency queue in another entry. The router stops
processing the QoS map as soon as it finds a match for the packet.
You can, however, configure a QoS map entry to both mark packets and place
them in a low-latency queue or CBWFQ class. Simply enter both the set
command and the priority or bandwidth command.
You can configure the router to mark:
traffic already marked with a QoS value
traffic with a specific source and/or destination IP address
traffic destined to a UDP protocol port
bridged traffic
No matter what type of traffic you want to mark, you configure the router in
the same way:
1. Create a QoS map entry.
2. Select the traffic to be marked.
3. Set the QoS value.
4. Assign the QoS map to an interface.

Creating a QoS Map Entry

To create a QoS map, enter the following command from the global configu-
ration mode context:
Syntax: qos map <mapname> <sequence number>
