To realize port remote management, it is necessary to define a dedicated VLAN, called
Remote-probe VLAN, on the three switches. All monitored packets are transmitted from
the source switch to the destination switch via this Remote-probe VLAN, thus packets
on remote ports of the source switch can be monitored on the destination switch. The
Remote-probe VLAN has the following features:
Port VLAN ID (PVID ) of all ports in the Remote-probe VALN cannot be
Remote-probe VLAN ID.
All ports in the Remote-probe VALN must be Trunk ports rather than Access or
Hybrid ports.
The Remote-probe VLAN cannot be a default VALN, management VLAN, Fabric
VALN or protocol VALN.
No remote source monitoring port should be in this Remote-probe VALN.

1.9.1 Prerequisites

The source switch, intermediate switch and destination switch are determined.
The source monitoring port, reflector port, destination monitoring port, and the
Remote-probe VLAN are determined.
Direction of the monitored packet is determined.
