Create a number-based basic ACL 2000 and enter it.
[SW8800] acl number 2000
Define ACL rule for the traffic from PC1.
[SW8800-acl-basic-2000] rule 0 permit source 1.0.0.1 0 time-range 3Com
3) Define the CoS—> Conform-Level mapping table.
Define the CoS — > Conform-Level mapping table. The switch allocates drop
precedence (all as 0 for the sake of simplification) for them when receiving packets.

4) Define the DSCP + Conform-Level —> Service parameter mapping table.
Define the DSCP + Conform-Level —> Service parameter mapping table. Allocate a
set of service parameters for the packets from PC1 according the mapping table for
DSCP 63.
