5.2.3 Using “SW (LAN1, LAN2)” to disable two local ports
This is an extreme example of software configuration! As mentioned, Bytton LTE is a very versatile
equipment.
Out of the four Ethernet ports, one is dedicated to WAN connection, but the others are fully configurable.
By default, they are joined together in a switch, but you can take LAN1 and LAN2 out of this switch and
assign them individual IP addresses and subnet masks.
A powerful application of this technique is
software disabling
of two of the Ethernet ports of Bytton LTE,
as described below.
Suppose you use Bytton ICR in an application that requires that the router features a single LAN port for
the users.
There are better solution than placing covers over the extra ports or asking the manufacturer NOT to
assemble the respective RJ-45 connectors!
The disabling of the ports that are not used may be performed from software, via the Web pages of
configuration (when you log-in as Superuser), respectively IP Settings, as explained below:
To software-disable two of the three LAN Ethernet ports of Bytton ICR, go to the Menu
LAN>IP Settings
and click the blue link “SW LAN1_LAN2”.
In the window “IP Settings SW” that shows up, set the SW (LAN1, LAN2) to
LAN1_LAN2
and enter for
both LAN ports the IP address ”255.255.255.255” and the subnet mask also “255.255.255.255”:
