iPRP
Requirements for using iPRP
● iPRP can only be used with the CLP iFeatures. For more detailed information, refer to the
section "Configuration License PLUG (CLP) (Page 24)".
● The Base Bridge mode "802.1Q VLAN Bridge" is set.
● The VLANs are created
● Access point mode: The VAP interface is enabled.
● Client mode: For "MAC Mode", "Layer 2 Tunnel" is set.
When should iPRP be used?
Note
iPRP with oversize frames (jumbo frames)
To be able to use oversize frames, oversize frames (jumbo frames) must be configured on all
devices in the network.
Agent VLAN (management VLAN) with iPRP
The iPRP VLAN can be used as the agent VLAN. This depends where the device is located.
● If the device is located in the PRP network A or PRP network B, use the VLAN that PRP A
or PRP B is assigned to as the agent VLAN.
● If the access points are located in both PRP networks, you can use one of the two VLANs
as the agent VLAN. As an alternative you can also use other VLANs as agent VLANs. The
division into PRP networks A and B must remain. A single management VLAN for all devices
in network A and B is not possible without further measures.
With the "industrial Parallel Redundancy Protocol" (iPRP) the PRP technology can be used in
a wireless network. With IPRP the PRP frames are transferred parallel via two wireless links.
The parallel transfer allows disruptions of the transfer on one wireless link to be compensated
on the other.
With transfer paths that are not the same, iPRP reduces the number of duplicated and out-of-
order packets. The application/protocol used must be able to handle the remaining duplicates
and out-of-order packets.
