This document describes and explains the function that activates IAPP for a particular ARF network. Other ARF networks are no longer affected in this case.

With the use of IAPP, access points can detect one another and exchange roaming information, e.g. the access point used until now is informed that a client is about to switch to a new access point. IAPP messages are sent by multicast to all connected networks and as a consequence they generate a large amount of traffic.

This can be avoided by defining an ARF network for management (e.g. OFFICE) and restricting IAPP to this network only.


1) You have defined multiple ARF networks and entered these into TCP/IP → Networks. The ARF network OFFICE is the management network.
2) Now specify the management network OFFICE for IAPP under Wireless LAN → Security → IAPP network. Now IAPP will only be operated on the ARF network OFFICE.

IAPP is disabled for all ARF networks if the entry specified under "IAPP network" is not a real ARF network as specified in the IP network table. The same result will occur if the ARF network is deleted from the IP network table but the entry for "IAPP network" remains unchanged!
