Qos Source-Port Priority; Assigning A Priority Based On Source-Port - HP PROCURVE 2610 Advanced Traffic Management Manual

Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure QoS for Outbound Traffic

QoS Source-Port Priority

QoS Classifier Precedence: 6
The QoS source-port option enables you to use a packet's source-port on the
switch as a QoS classifier. Where a particular source-port classifier has the
highest precedence in the switch for traffic entering through that port, then
traffic received from the port is marked with the source-port classifier's
configured priority level. Different source-port classifiers can have different
priority levels.
Options for Assigning Priority. Priority control options for packets from
a specified source-port include:

(For operation when other QoS classifiers apply to the same traffic, refer to
"Classifiers for Prioritizing Outbound Packets" on page 6-9.)

Assigning a Priority Based on Source-Port

This option assigns a priority to outbound packets having the specified source-
port. Configure this option by either specifying the source-port ahead of the
qos command or moving to the port context for the port you want to configure
for priority. (For configuring multiple source-ports with the same priority, you
may find it easier to use the interface < port-list > command to go to the port
context instead of individually configuring the priority for each port.)
Syntax: interface < port-list > qos priority < 0 - 7 >
6-52
802.1p priority
DSCP policy (Assigning a new DSCP and an associated 802.1p priority;
inbound packets must be IPv4.)
Configures an 802.1p priority for packets entering the switch
through the specified (source) ports. This priority determines
the packet queue in the outbound port(s) to which traffic is
sent. If a packet leaves the switch on a tagged port, it carries
the 802.1p priority with it to the next downstream device. You
can configure one QoS classifier for each source-port or group
of source-ports. (Default:
no interface < port-list > qos
Disables use of the specified source-port(s) for QoS
classifier(s) and resets the priority for the specified source-
port(s) to
