Using QoS Classifiers to Configure Quality of Service for Outbound Traffic

QoS Source-Port Priority

QoS Classifier Precedence: 2
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 on the Switch. Priority control options
for packets from a specified source-port include:
802.1p priority
DSCP policy (Assigning a new DSCP and an associated 802.1p priority;
inbound packets must be IPv4.)
(For operation when other QoS classifiers apply to the same traffic, refer to
"Classifiers for Prioritizing Outbound Packets" on page 5-10.)
Options for Assigning Priority From a RADIUS Server. You can use a
RADIUS server to impose a QoS source-port priority during an 802.1X port-
access authentication session. Refer to the RADIUS chapter in the Access
Security Guide for your switch.

Assigning a Priority Based on Source-Port

This option assigns a priority to all outbound packets having the specified
source-port. You can 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. (If you are 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 >
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:
Quality of Service (QoS): Managing Bandwidth More Effectively
)
