Examples of command usage
Enable the QoS advanced mode. Divide traffic into queues: the first queue is for DSCP 12
packets, the second one is for DSCP 16 packets. The eighth one is a priority queue. Create a
traffic classification strategy for ACL that allows transfer of TCP packets with DSCP 12 and 16
and sets the following rate limitations: average rate 1000 kbps, threshold 200,000 bytes. Use
the strategy for Ethernet 14 and 16 interfaces.
