Local QoS ID marking configuration example
Local QoS ID marking is mainly used for re-classifying packets of multiple classes to perform a uniform
set of actions on them as a re-classified class.
Consider the case of limiting the total rate of packets with source MAC address 0001-0001-0001 and
packets with source IP address 1.1.1.1 to 128 kbps. Without QoS local ID marking, you can only assign
fixed bandwidth to the two classes by associating each of them with a rate-limit traffic behavior. With
QoS local ID marking, however, traffic limit applies to the two classes as a whole, allowing the switch to
dynamically assign the bandwidth to the two classes depending on their traffic size.
To configure local QoS ID marking to limit the total rate of the two classes, you need to mark packets of
the two classes with the same local QoS ID; create a class to match the QoS local ID, and associate this
class with the traffic policing action.
