Switch Ports involved Function
Trunk port
Receives remote mirrored packets.
Destination
switch
Destination port
Monitors remote mirrored packets
To implement remote port mirroring, you need to define a special VLAN, called
remote-probe VLAN, on a switch. All mirrored packets will be transferred from the
source switch to the destination ports of the destination switch through this VLAN. Thus,
the destination switch can monitor the port packets sent from the ports of the source
switch. Remote-probe VLAN requires that:
z All ports connecting the devices in remote-probe VLAN are configured as the trunk
ports.
z The default VLAN and management VLAN cannot be configured as remote-probe
VLAN.
z Layer 2 interoperability must be ensured by configuration between the source and
destination switches over the remote-probe VLAN.
Caution:
To ensure the normal packet mirroring, it is not recommended to perform any of the
following operations on the remote-probe VLAN:
z Configuring a source port to the remote-probe VLAN that is used by the local
mirroring group;
z Configuring a Layer 3 interface for the remote-probe VLAN;
z Configuring to run other protocol packets, or bear other service packets;
z Using remote-probe VLAN as a special type of VLAN, such as voice VLAN or
protocol VLAN;
z Configuring other VLAN-related functions.
