Reserving IP Addresses in DHCP Servers
The EMX uses its serial number as the client identifier in the DHCP
request. Therefore, to successfully reserve an IP address for the EMX in
a DHCP server, use the EMX device's serial number as the unique ID
instead of the MAC address.
Since all network interfaces of the EMX can be simultaneously enabled
and configured with diverse static IP addresses, the client identifier of
each network interface is different. The main difference is the
absence/presence of a suffix, which is the interface name added to the
end of the serial number. The table below lists the client identifiers of all
network interfaces.
Interface Client Identifier
ETHERNET serial number
WIRELESS serial number plus the uppercase suffix "-WIRELESS"
BRIDGE serial number
You can reserve the IP addresses of more than one interfaces in the
DHCP server if preferred. Note that you must choose/configure the
bridge interface if your EMX is set to the bridging mode.
Important: In the bridging mode, only the IP parameters of the
BRIDGE interface function. The IP parameters of the ETHERNET and
WIRELESS interfaces do NOT function.
