# Create a local port mirroring group.
[Sysname] mirroring-group 1 local
# Assign port Ethernet 1/1/1 and Ethernet 1/1/2 to the port mirroring group as mirroring
ports. Assign port Ethernet 1/1/3 to the port mirroring group as the monitor port.

After finishing the configuration, you can monitor all the packets received and sent by
Host A and Host B on the server.

1.5.2 Remote Port Mirroring Configuration Example

I. Network requirements
On a network shown in
Host A is connected to port Ethernet 1/1/1 of Switch A.
Host B is connected to port Ethernet 1/1/2 of Switch A.
Port Ethernet 1/1/3 of Switch A is connected to port Ethernet 1/1/1 of Switch B.
Both ports are trunk ports.
Port Ethernet 1/1/2 of Switch B is connected to port Ethernet 1/1/1 of Switch C.
Both ports are trunk ports.
A server is connected to port Ethernet 1/1/2 of Switch C.
To monitor packets of Host A and Host B on the server, you can configure remote port
mirroring groups on the switches as follows:
On Switch A, create a remote source mirroring group; create VLAN 2 and
configure it as the remote probe VLAN; assign ports Ethernet 1/1/1 and Ethernet
1/1/2 to the port mirroring group as mirroring ports and port Ethernet 1/1/4 as the
reflector port.
Configure port Ethernet 1/1/3 of Switch A, ports Ethernet 1/1/1 and Ethernet 1/1/2
of Switch B, and port Ethernet 1/1/1 of Switch C as trunk ports and configure them
to permit packets of VLAN 2.
