Placing Traffic In A Low-Latency Queue; Creating A Qos Map Entry; Selecting The Traffic To Be Placed In The Low-Latency Queue - HP 7102dl - ProCurve Secure Router Configuration Manual

Placing Traffic in a Low-Latency Queue

The ProCurve Secure Router guarantees traffic in a low-latency queue the
amount of bandwidth you specify. Traffic can burst above this bandwidth, but
if the line becomes congested, the router will drop bursting packets in favor
of other traffic.
The QoS map entry both selects traffic for the queue and assigns the queue a
bandwidth.
To configure LLQ, you must complete these steps:
1. Create a QoS map entry.
2. Match the entry to traffic that meets your criteria.
3. Set the queue's maximum guaranteed bandwidth.
4. Apply the QoS map to a WAN interface.
You can place the following traffic in a low-latency queue:
traffic marked with a certain ToS value
traffic with a certain source and/or destination IP address and port
traffic destined to a certain range of UDP protocol ports
bridged traffic

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>
The sequence number indicates the priority for the QoS map entry. Because
the ProCurve Secure Router searches entries with the lowest numbers first,
the lower the map's number, the higher its priority. For example, enter:
ProCurve(config)# qos map LowLatency 10

Selecting the Traffic to Be Placed in the Low-Latency Queue

You select the traffic that the QoS map entry will mark by entering one of the
match commands shown in Table 8-10.
