2.3.3 Traffic Priority Configuration Example

I. Network requirements
Re-allocate service parameters according to the mapping table for DSCP 63 for the
packets from PC1 (IP 1.0.0.1) during the time range 8:00 to 18:00 everyday.

III. Configuration procedure
1) Define the time range.
# Define the time range from 8:00 to 18:00.
[H3C] time-range H3C 8:00 to 18:00 daily
2) Define the traffic from PC1.
# Create a number-based basic ACL 2000 and enter it.
[H3C] acl number 2000
# Define ACL rule for the traffic from PC1.
[H3C-acl-basic-2000] rule 0 permit source 1.0.0.1 0 time-range H3C
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.
[H3C] qos cos-drop-precedence-map 0 0 0 0 0 0 0 0
The modified CoS—> Conform-Level mapping table:

GE7/1/2 GE7/1/2
