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
Enable port mirroring – STP
collaboration
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
cannot be configured with functions like VLAN-VPN, port loopback detection, packet filtering, QoS,
port security, and so on.
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.
Use the command...
