3.2.3 QoS control settings for TCP/UDP port-number

The following shows an example of setting QoS control based on specification of a range of UDP port numbers as the flow detection condition.

Points to note

When frames are received, flow detection for QoS control is performed based on the range of destination port numbers in the UDP header.

Command examples

1. (config)# ip qos-flow-list QOS-LIST1

   Creates an IPv4 QoS flow list (QOS-LIST1), and then switches to IPv4 QoS flow list mode. By creating this list, IPv4 QoS flow list mode is entered.

2. (config-ip-qos)# qos udp any any range 10 20 action cos 6

   Set QoS flow list with CoS = 6 with the destination port number from 10 to 20 in UDP header as the flow detection condition.

3. (config-ip-qos)# exit

   Returns to global configuration mode from IPv4 QoS flow list mode.

4. (config)# interface gigabitethernet 1/0/1

   Moves to port 1/0/1 interface mode.

5. (config-if)# ip qos-flow-group QOS-LIST1 in

   Enables the IPv4 QoS flow list on the receiving side.
