as the remote-probe VLAN
Return to system view
Enter the view of the Ethernet
port that connects to the
intermediate switch or
destination switch
Configure the current port as
trunk port
Configure the trunk port to
permit packets from the
remote-probe VLAN

Create a remote source
mirroring group
Configure source port(s) for
the remote source mirroring
group
Configure the reflector port for
the remote source mirroring
group
Configure the remote-probe
VLAN for the remote source
mirroring group
When configuring the source switch, note that:
The S3100-SI series do not support the both keyword in the source port configuration for a remote
source mirroring group.
All ports of a remote source mirroring group are on the same device. Each remote source mirroring
group can be configured with only one reflector port.
The reflector port cannot be a member port of an aggregation group, or a port enabled with LACP
or STP. It must be an access port and cannot be configured with the functions like VLAN-VPN, port
loopback detection, packet filtering, QoS, port security, and so on.
It is recommended not to configure the VLAN mapping and the selective QinQ function on the
reflector port; otherwise, port mirroring may not function properly.
You cannot modify the duplex mode, port rate, and MDI attribute of a reflector port.
Only an existing static VLAN can be configured as the remote-probe VLAN. To remove a
remote-probe VLAN, you need to restore it to a normal VLAN first. A remote port mirroring group
gets invalid if the corresponding remote port mirroring VLAN is removed.
Do not configure a port connecting the intermediate switch or destination switch as the mirroring
source port. Otherwise, traffic disorder may occur in the network.
