3.5.4 Configuring a combination of maximum bandwidth control and minimum bandwidth monitoring

The following describes how to perform maximum bandwidth control and minimum bandwidth monitoring (updating the DSCP value of non-compliant frames) on certain types of flows.

Points to note

When frames are received, first flow detection is performed based on the destination IP address, and then bandwidth monitoring using maximum bandwidth control and minimum bandwidth monitoring is performed. The DSCP value of any non-compliant frames found during minimum bandwidth monitoring is changed.

Command examples

1. (config)# ip qos-flow-list QOS-LIST4

   Creates a IPv4 QoS flow list (QOS-LIST4). By creating this list, IPv4 QoS flow list mode is entered.

2. (config-ip-qos)# qos ip any host 192.168.130.10 action max-rate 5M max-rate-burst 512 min-rate 1M min-rate-burst 64 penalty-dscp 8

   Configures the IPv4 QoS flow list for flows whose destination IP address is 192.168.130.10.The command sets a monitoring bandwidth for maximum bandwidth control of 5 Mbit/s, a maximum-bandwidth-control burst size of 512 KB, a minimum monitoring bandwidth of 1 Mbit/s, a minimum-monitoring-bandwidth burst size of 64 KB, and a DSCP value of 8 for non-compliant frames in minimum bandwidth monitoring.

3. (config-ip-qos)# exit

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

4. (config)# interface gigabitethernet 1/0/7

   Switches to the interface mode of port 1/0/7.

5. (config-if)# ip qos-flow-group QOS-LIST4 in

   Enables the IPv4 QoS flow list (QOS-LIST4) on the receiving side.
