The device can serve as a source switch, an intermediate switch, or a destination switch in a remote
port mirroring networking environment.
Configuration on the device acting as a source switch
1) Configuration prerequisites
The source port, the reflector port, and the remote-probe VLAN are determined.
Layer 2 connectivity is ensured between the source and destination switches over the
remote-probe VLAN.
The direction of the packets to be monitored is determined.
2) Configuration procedure

Enter system view
Create a VLAN and enter the VLAN view
Configure the current VLAN as the

from the remote-probe VLAN
Return to system view
