232 CHAPTER 7: QOS/ACL OPERATION
Define a mirroring group, with the monitoring port as GigabitEthernet3/1/8.
[SW8800]mirroring-group 1 inbound GigabitEthernet3/1/1
GigabitEthernet3/1/2 mirrored-to GigabitEthernet3/1/8
[SW8800]mirroring-group 2 outbound GigabitEthernet3/1/1
GigabitEthernet3/1/2 mirrored-to GigabitEthernet3/1/8
Traffic Priority
Configuration Example
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.

1 Define the time range from 8:00 to 18:00.
[SW8800]time-range 3com 8:00 to 18:00 daily
2 Define the traffic from PC1.
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

3 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.
