Network requirements
On the network as shown in
to Ethernet 1/0/1 of the switch. A data monitoring device is connected to Ethernet 1/0/2 of the switch.
Monitor and analyze packets sent by Host A on the data monitoring device.

Configuration procedure
Configure the 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
# Create class 1 and configure the class to use ACL 2000 for traffic classification.
[Sysname] traffic classifier 1
[Sysname-classifier-1] if-match acl 2000
[Sysname-classifier-1] quit
# Create behavior 1 and configure the action of mirroring traffic to Ethernet 1/0/2 in the traffic
behavior.
[Sysname] traffic behavior 1
[Sysname-behavior-1] mirror-to interface Ethernet 1/0/2
