Assigning an 802.1p Priority for a Global TCP/UDP Classifier

To mark matching TCP or UDP packets with an 802.1p priority, enter the
following command:
Syntax: qos < udp-port | tcp-port > [ ipv4 | ipv6 | ip-all ] <port-number | range start
end > priority < 0 - 7 >
Marks an 802.1p priority in outbound packets with the
specified TCP or UDP application-port number, where:
• ipv4 marks only IPv4 packets (default).
• ipv6 marks only IPv6 packets.
• ip-all marks all IP traffic (both IPv4 and IPv6 packets).
• port-number is a TCP/UDP port number from 1 to 65535.
• range start end specifies a range of TCP/UDP ports; see
"Operating Notes on Using TCP/UDP Port Ranges" on page
5-23. If you specify a range, the minimum port number
must precede the maximum port number in the range.
• priority <0-7> marks the specified 802.1p priority in
matching TCP or UDP packets.
The 802.1p priority determines the packet's queue in the
outbound port on the switch. If the packet leaves the switch
on a tagged VLAN port, it carries the 802.1p priority with it
to the next downstream device.
Default: Disabled — No 802.1p priority is assigned.
The no form of the command deletes the specified UDP or TCP
port number or range of port numbers as a QoS classifier.
Note: If you have specified a range of port numbers, you
must specify the entire range in the no command; you cannot
remove part of a range.
