Source port
Port monitored. It copies packets to the
reflector port through local port mirroring.
There can be more than one source port.
Reflector port
Receives packets from the source port
and broadcasts the packets in the
remote-probe VLAN.
Source switch
Trunk port
Sends mirrored packets to the
intermediate switch or the destination
switch.
Intermediate
switch
Trunk port
Sends mirrored packets to the
destination switch.
Two trunk ports are necessary for the
intermediate switch to connect the
devices at the source switch side and the
destination switch side.
Trunk port Receives remote mirrored packets.
Destination switch
Destination port
Receives packets forwarded from the
trunk port and transmits the packets to
the data detection device.
Caution:
z Do not configure a default VLAN, a management VLAN, or a dynamic VLAN as the
remote-probe VLAN.
z Configure all ports connecting the devices in the remote-probe VLAN as trunk ports,
and ensure the Layer 2 connectivity from the source switch to the destination switch
over the remote-probe VLAN.
z Do not configure a Layer 3 interface for the remote-probe VLAN, run other protocol
packets, or carry other service packets on the remote-prove VLAN and do not use
the remote-prove VLAN as the voice VLAN and protocol VLAN; otherwise, remote
port mirroring may be affected.
