-
Display information on fields replacement in packets which are used
by QoS.
- dscp-queue - table of correspondence between DSCP and queues;
- dscp-dp - table of correspondence between DSCP tags and drop
priority (DP);
- policed-dscp - table of DSCP remarking;
- dscp-mutation - DSCP-to-DSCP changes table.
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.
