Figure 29. Example Configuration of a Modem in VLAN Pass-Through Mode.
VLAN Implementation using Modems in Bridge Mode:
Configuration of the Gateway is the same when operating the Modems in Bridge mode.
There are a few differences that you must keep in mind when the modem is in Bridge
Mode.
•
It is recommended that DHCP not be enabled for devices connected to the Modem
since DHCP requests are tagged with the VPID.
•
Ethernet devices connected to Powerline Modems can be configured for VLAN pass-
through by entering the VPID (VLAN Pass-Through ID) next to the MAC address of
the device. Note: The Modem can only support 128 VPID devices.
•
Again, ensure that the Management VID is not used as VPID.
•
You may mix Bridge mode and NAT mode Modems on the same Powerline network.
Gateway LUID Range Configuration
Firmware version 2.0 allows for the configuration of the LUID range assignment for
Powerline MU modems (seeFigure 30). This feature allows the ISP full control over their
Powerline deployment by controlling the number of Modems which can register to a
particular Gateway, which can be particularly useful in large-scale MDU deployments. It
is highly recommended that this feature be used to prevent packet collision from Modems
in the same Powerline network by ensuring that multiple Gateways do not assign
overlapping Modem LUIDs.
Note: When deploying multiple Gateways over the same electric grid, it is important to
isolate the Gateways either electrically or ensure that they are using different NEKs.
