Configure and Validate 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).

Configure Point to Multipoint Topology from CLI
Use these commands to configure a Fluidmax (point-to-multipoint) topology.
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 - 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.

Cluster ID: This is an ID assigned to an interface when it is set in Fluidmax mode. This ID should be the same for primary and backup primary nodes. It helps in identifying and grouping devices that belong to the same cluster.
Tower ID: This is used to enable or disable the Fluidmax Tower ID for a specified interface.
![]() Note |
Tower ID is used in configurations where there is a Gateway + Mesh Point (MP) – MP with the same tower ID. |
Use these commands to configure the interface, cluster id, and tower id in Fluidmax mode.
Fluidmax - Set the interface in Fluidmax mode.
Primary | Secondary - Fluidmax role for the device, either primary or secondary.
Device# configure dot11Radio [1|2] mode fluidmax cluster id fluidmesh
Cluster id - Set Fluidmax Cluster ID assigned to the interface.
Device# configure dot11Radio [1|2] mode fluidmax tower [enable|disable]
Tower – Enable or disable Fluidmax Tower ID for specified interface.
