iPCF-MC

Note
Use of iPCF with other iFeatures
The function iPCF-MC and other iFeatures (e.g. iPCF, iPCF-HT, iPRP) are not compatible
with each other and cannot be used at the same time on a device.
Assignment of the interfaces
With 11n devices, remember that the assignment of the WLAN interfaces is fixed for iPCF-
MC.
• WLAN1: Data interface
• WLAN2: Management interface
Requirements to be able to use iPCF-MC:
● The access point has at least two WLAN interfaces (dual AP).
● Access point mode: Only dual APs with KEY-PLUG W780 iFeatures (MLFB 6GK5 907-
8PA00)
● Client mode: Client with KEY-PLUG W740 iFeatures (MLFB 6GK5 907-4PA00)
● The management interface and data interface must be operated in the same frequency
band and mode and must match in terms of their wireless coverage. iPCF-MC will not
work if both wireless interfaces are equipped with directional antennas that cover different
areas.
● The management interfaces of all access points to which a client can change must use
the same channel. A client scans only this one channel to find accessible access points.
● Transmission based on IEEE801.11h (DFS) cannot be used for the management
interface. For the data interface 801.11h (DFS) is possible.
● The client cannot be operated with "Use Allowed Channels only".
● "Force roaming on link down" is automatically mirrored on the second interface.
● The following applies to clients: All configured and active SSIDs must be assigned
security context 1. An SSID is active when the corresponding check box "Enabled" is
selected on the "Interfaces > WLAN > Client" page.
● In Japan, iPCF-MC cannot be enabled if the data or management interface uses a
frequency of the 4920 MHz - 5080 MH frequency band.
