Configuration on a switch acting as a source switch
1) Configuration prerequisites
The source port, the reflector port, and the remote-probe VLAN are determined.
Layer 2 connectivity is ensured between the source and destination switches over the
remote-probe VLAN.
The direction of the packets to be monitored is determined.
2) Configuration procedure
Follow these steps to perform configurations on the source switch:
To do...
Enter system view
Create a VLAN and enter the
VLAN view
Configure the current VLAN 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
Return to system view
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:
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 existing mirroring group, a fabric port, a member
port of an aggregation group, or a port enabled with LACP or STP. It must be an access port and
