The access points (AP 1, AP 2 and AP 3) and the RedBox at the AP end are connected to
each other via a switch. PRP network A und B are separated from each other via VLANs.
If SAN1 sends a frame to SAN2, the frame is duplicated by the RedBox at the AP end and
the two redundant frames are transferred via the switch to the access points. Via the two
different wireless paths the redundant PRP frames are transferred to the RedBox at the
client end. The clients are also connected to their RedBox via a switch. This forwards the
first PRP frame to arrive to SAN2 and discards the second one.
Note
On the interfaces of the switches to the SCALANCE W700 devices, only the VLANs that are
also set on the VAP or WLAN interfaces of the SCALANCE W700 devices may be
configured.
