To implement remote port mirroring, you need to define a special VLAN, called
remote-probe VLAN, on all the three types of switches. All mirrored packets will be
transferred to the mirrored ports of the destination switch from the source switch via this
VLAN. Thus, the destination switch can monitor the port packets sent from the remote
ports of the source switch. remote-probe VLAN requires that:
It is recommended that you configure all ports connecting the devices in
remote-probe VLAN to the trunk type.
The default VLAN and management VLAN cannot be configured as remote-probe
VLAN.
Required configurations are performed to ensure Layer 2
source and destination switches over the
Caution:
To ensure the normal packet mirroring, you are not recommended to perform any of the
following operations on the remote-probe VLAN:
Configuring a source port to the remote-probe VLAN that is used by the local
mirroring group;
Configuring a Layer 3 interface for the remote-probe VLAN;
Running other protocol packets, or bearing other service packets;
Using remote-probe VLAN as a special type of VLAN, such as voice VLAN or
protocol VLAN;
Configuring other VLAN-related functions.
