652 CHAPTER 59: MIRRORING CONFIGURATION

To define a destination port for mirroring, you can also enter the port view of the

specified port directly to execute the mirroring-group group-id monitor-port

command. Refer to corresponding command manual for detail.

Configuration example

1 Network requirements:

■ GigabitEthernet 1/0/1 on the switch is connected to the 10.1.1.1/24 network

segment.

■ Mirror the packets from the 10.1.1.1/24 network segment to GigabitEthernet

1/0/4, the destination port.

2 Configuration procedure:

<SW7750> system-view

[SW7750] acl number 2000

[SW7750-acl-basic-2000] rule permit source 10.1.1.1 0.0.0.255

[SW7750-acl-basic-2000] quit

[SW7750] mirroring-group 3 local

[SW7750] mirroring-group 3 monitor-port GigabitEthernet 1/0/4

[SW7750] interface GigabitEthernet 1/0/1

[SW7750-GigabitEthernet1/0/1] mirrored-to inbound ip-group 2000

interface GigabitEthernet 1/0/4
