Figure 5-4. Configuring 802.1p Priority Assignments on TCP/UDP Ports
Assigning a DSCP Policy for a Global TCP/UDP Classifier
This global QoS packet-marking option assigns a previously configured or
default DSCP policy (codepoint and 802.1p priority) to TCP or UDP packets
having the specified port number or range of port numbers. When assigning a
DSCP policy, the switch performs the following actions:
1.
Selects an incoming IP packet if the TCP or UDP port number it carries
matches the port number specified in the TCP or UDP classifier (as shown
in figure 5-4, above).
2.
Overwrites (re-marks) the packet's DSCP with the new DSCP configured
for matching packets.
3.
Assigns the 802.1p priority associated with the new DSCP. (See "Differen-
tiated Services Codepoint (DSCP) Mapping" on page 5-90.)
4.
Forwards the packet through the appropriate outbound port queue.
Creating a DSCP Policy Based on TCP/UDP Port Number Classifiers.
The following procedure creates a DSCP policy for IP packets carrying the
selected TCP or UDP port-number classifier.
