PERATION

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.

Figure 11 Networking for a QoS configuration

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

3com

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.

[SW8800]qos cos-drop-precedence-map 0 0 0 0 0 0 0 0

The modified CoS-> Conform-Level mapping table:

GE7/1/8

GE7/1/1

GE7/1/2

VLAN2,

1.0.0.1/8

VLAN3,

2.0.0.1/8
