4.2.1
Mesh Network Addressing and Configuration.
The Fluidmesh network can be configured in either
Layer 2 Addressing
Mode
or
Layer 3 Addressing Mode
:
1.
Layer 2 Addressing Mode:
all the network devices (both the FMunits
and the video-surveillance devices) can be configured according to
private LAN addressing adopted for the control room.
2.
Layer 3 Addressing Mode:
both the FMunits and the video-surveillance
devices (cameras, encoders, etc.) are configured according to the
Fluidmesh IP addressing, as described in Section 4.4.
In both cases, each FMunit is provided with a unique
unit ID
with the fol-
lowing format:
5.a.b.c
where the triplet
h
a,b,c
i
univocally identifies the unit and cannot be changed.
Irrespective of the addressing mode adopted, the unit ID is used to identify
the units throughout the Web-based Graphical User Interface (GUI).
By default, each FMunit operates in the Layer 2 Addressing mode which
is presented in Section 4.3. The Layer 3 Addressing Mode is described
in Section 4.4. Finally, we discuss how to configure the FM2200 devices
through the Web GUI in Section 5.
4.3
Mesh Network Layer 2 Addressing
The Layer 2 Addressing Mode allows configuring each FMunit and each
device connected to the FMunits 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. 4.3.
When the Layer 2 Addressing Mode is enabled, the Fluidmesh network
logically becomes part of the private LAN where (usually) the control room
resides. Therefore, both the FMunits and any other edge device (cameras,
encoders, etc.) should be provided with a private LAN IP address and will
be accessed through that specified IP address.
Consider the example of Fig. 4.3 where the private LAN IP address 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 ad-
dress must be univocal within the entire network to avoid address con-
flicts. The
default IP address
of each FMunit 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 univocally identify each FMunit.
