Assigning a priority for a global layer 3 protocol classifier
This global QoS packet-marking option assigns an 802.1p priority to outbound packets having
the specified Layer-3 protocol.
Syntax:
qos protocol [ ip | ipx | arp | 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 downstream device. You can configure one QoS classifier for each
protocol type.
Default: No-override
no qos protocol ip | ipx | arp | appletalk | sna | netbeui
priority 0 - 7
Disables use of the specified protocol as a QoS classifier and resets the protocol
priority to No-override.
