Figure 5.2: Fluidmesh network addressing.
5.2.1 Network Addressing
The Fluidmesh layer 2 addressing allows configuring each FM unit and
each device connected to the FM units according to the IP address class
used within the private LAN to which the Mesh End unit is connected. A
sample network configuration is shown in Fig. 5.2.
The Fluidmesh network logically becomes part of the private LAN where
(usually) the control room resides. Therefore, both the FM units and any
other edge device should be provided with a private LAN IP address and
will be accessed through that specified IP address.
Consider the example depicted in Fig. 5.2 where the private LAN IP ad-
dress class is 192.168.150.0 with netmask 255.255.255.0. Each device is
configured with an IP address belonging to this class. Please note that
each IP address must be univocal within the entire network to avoid ad-
dress conflicts. The default IP address of each FM unit is 192.168.0.10
with netmask 255.255.255.0. Finally, please note that the default factory-
set 5.a.b.c unit IDs are still valid and used to unambiguously identify each
FM unit.
Multiple FM units can be connected together through a network switch to
form clusters of radios if needed. The Fluidmesh
proprietary routing proto-
col will be run automatically on the cabled segment of the network. Please
note that the units must be operated in Mesh Point mode only to activate
the cluster feature.
