1.15.2 Configuration Example of Priority Marking

I. Network requirements

Mark ef on the packets that PC1 with IP address 1.0.0.2 sends from 8:00 to 18:00 every

day to provide the precedence for the upper-layer devices to use.

III. Configuration procedure

1) Define the time rang from 8:00 to 18:00

# Define the time range.

<H3C> system-view

[H3C] time-range test 8:00 to 18:00 daily

2) Define the traffic rules of PC packets

# Enter number-identification-based basic ACL view identified.

[H3C] acl number 2000

[H3C-acl-basic-2000] rule 0 permit source 1.0.0.1 0 time-range test

[H3C-acl-basic-2000] quit

3) Mark the ef precedence on the packets PC1 sends
