Configuring and Validating Fluidmax (point to multipoint) Topology
For fixed infrastructure, any wireless interface can be configured to operate in Fluidmax mode to implement point-to-multipoint connections. Each interface uses an independent set of Fluidmax parameters, allowing for great flexibility in the network topologies that can be implemented. As an example, the below image explains two cascaded point-to-multipoint clusters where the ME (Mesh End) node uses both radios in Fluidmax Primary mode to serve several secondary clients (MP1 (Mesh Point), MP2, and MP3) on two different frequencies. For MP2, the first radio operates in Fluidmax secondary mode to connect to the ME, while the second interface is configured as Fluidmax Primary to serve more downstream clients (MP4 and MP5).
Configuring Point to Multipoint Topology using CLI
To configure a Fluidmax (point-to-multipoint) topology, use the following commands:
Device#configure dot11Radio <interface>
Interface - <0-3> dot11Radio interface number
Device#configure dot11Radio <interface> {enable | disable}
Enable or disable - Set wireless interface admin state to enable or disable at runtime
Device#configure dot11Radio <interface> mode {fluidity | fixed | fluidmax } { primary | secondary }
Mode - Operating mode for the specified interface (Fluidity or Fixed or Fluidmax)
Primary | secondary - Fluidity, Fixed, and Fluidmax role for the device, either primary or secondary
Device#configure dot11Radio <interface> channel <channel id>
Channel - Set the operating channel id <1 – 256>
Device#configure dot11Radio <interface> band-width <channel bandwidth>
Bandwidth - channel bandwidth in MHz and currently supported values are 20, 40, 80, and 160.
