Configuration example
Configure VLAN-based mirroring to mirror the packets received by all ports in
■
VLAN 2.
The destination port is GigabitEthernet1/0/2.

The RSPAN feature of S4200G allows for MAC-based and VLAN-based remote
mirroring.
You can implement MAC-based and VLAN-based remote mirroring by performing
MAC-based and VLAN-based configurations on the remote source mirroring group of
the source switch.
Configuration prerequisites
The source switch, intermediate switch, and the destination switch have been
■
determined.
The source port, the reflector port, the destination port, and the Remote-probe
■
VLAN have been determined.
The direction of the packets to be monitored has been determined.
■
Intermediate switch and source switch support the function of
■
MAC-learning-disabled-based-on-VLAN, which also is enabled for Remote-probe
VLAN.
If you are configuring MAC-based remote mirroring, verify that the MAC address
■
you enter is a static MAC address that already exists in the MAC address entries.
If you are configuring VLAN-based remote mirroring, determine the corresponding
■
VLAN ID.
