Traffic Mirroring Configuration Example

Network Requirements

The user's network is as described below:
Host A (with the IP address 192.168.0.1) and Host B are connected to GigabitEthernet1/0/1 of the
switch.
The data monitoring device is connected to GigabitEthernet1/0/2 of the switch.
It is required to monitor and analyze packets sent by Host A on the data monitoring device.

Configuration Procedure

Configure Switch:
# Enter system view.
<Sysname> system-view
# Configure basic IPv4 ACL 2000 to match packets with the source IP address 192.168.0.1.
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule permit source 192.168.0.1 0
[Sysname-acl-basic-2000] quit
# Configure a traffic classification rule to use ACL 2000 for traffic classification.
[Sysname] traffic classifier 1
[Sysname-classifier-1] if-match acl 2000
[Sysname-classifier-1] quit
# Configure a traffic behavior and define the action of mirroring traffic to GigabitEthernet1/0/2 in the
traffic behavior.
[Sysname] traffic behavior 1
[Sysname-behavior-1] mirror-to interface GigabitEthernet 1/0/2
