Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure Quality of Service for Outbound Traffic
QoS Layer-3 Protocol Priority (5300xl Switches Only)
(This feature is available only on the Series 5300xl switches.)
QoS Classifier Precedence: 4
The QoS protocol option enables you to use these protocols as QoS classifiers:
■ IP
■ IPX
■ ARP
■ DEC_LAT
■ Appletalk
■ SNA
■ Netbeui
Options for Assigning Priority. Priority control for the Layer-3 protocol
classifier includes assigning only the 802.1p priority. The switch does not use
this classifier for assigning DSCP-based priority.
Assigning a Priority Based on Layer-3 Protocol
When QoS on the switch is configured with a Layer-3 protocol as the highest-
precedence classifier and the switch receives traffic carrying that protocol,
then this traffic is assigned the priority configured for this classifier. (For
operation when other QoS classifiers apply to the same traffic, refer to
“Classifiers for Prioritizing Outbound Packets” on page 8-9.)
Syntax:
qos protocol
< ip | ipx | arp | dec_lat | appletalk | sna | netbeui > priority < 0 - 7 >
Configures an 802.1p priority for outbound packets
having the specified protocol. This priority determines
the packet’s queue in the outbound port to which it is
sent. If the packet leaves the switch on a tagged port, it
carries the 802.1p priority with it to the next down-
stream device. You can configure one QoS classifier for
each protocol type. (Default:
No-override
)
no qos protocol
< ip | ipx | arp | dec_lat | appletalk | sna | netbeui >
Disables use of the specified protocol as a QoS classifier
and resets the protocol priority to
No-override
.

settings.
