Modular QoS CLI Classification
The Quality of Service mechanisms that have been added to the Cisco IOS all had
their own set of classification options. For example:
n Committed Access Rate (CAR) can classify packets by using:
– Access lists
– QoS group
– DSCP
– Rate limit access list
n Traffic Shaping (GTS) can classify packets by using access lists
n Priority Queuing (PQ) and Custom Queuing (CQ) can classify packets by
using:
– Access lists
– Packets size
– Fragment
– TCP or UDP port number
The Modular Quality of Service Command Line Interface (MQC) was introduced
to allow any supported classification to be used with any QoS mechanism....
