3.2.3 QoS control setting by TCP/UDP port number

This section explains how to set QoS control using UDP port number as the flow-detection condition.

Points to note

When a frame is received, QoS control is performed by detecting the destination port number in UDP headers.

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 eq 10 action cos 6

   Set the destination port number 10 in UDP header as the flow detection condition, and set QoS flow list with CoS = 6.

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.
