To implement the remote port management, a special VLAN, called Remote-probe 
VLAN, needs to be defined in all three types of switches. All the mirrored packets will 
be forwarded to destination switch from the source switch using this VLAN, and 
therefore the destination switch can monitor the port packets sent from the source 
switch.

Remote-probe VLAN has the following characteristics:

■

None of the ports in this VLAN should have their PVID (Port VLAN ID) set as 
Remote-probe VLAN ID.

■

All the ports in this VLAN must be Trunk ports, rather than Access ports or Hybrid 
ports.

■

The default VLAN, Management VLAN, Fabric VLAN, and Protocol VLAN cannot 
be configured as Remote-probe VLAN.

■

Remote-probe VLAN cannot have the source ports of remote mirroring.

■

Specify the source switch, intermediate switch, and the destination switch.

■

Specify the source port, the reflector port, the destination port, and the 
Remote-probe VLAN. 

■

Specify whether the packets to be monitored are inbound or outbound.

■

Intermediate switch and source switch support the function of 
MAC-learning-disabled-based-on-VLAN, which also is enabled for Remote-probe 
VLAN.
