Reserving IP Addresses in DHCP Servers
The Legrand PDU uses its serial number as the client identifier in the DHCP request. Therefore, to
successfully reserve an IP address for the Legrand PDU in a DHCP server, use the Legrand PDU device's
serial number as the unique ID instead of the MAC address.
Since all network interfaces of the Legrand PDU 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
ETH1 serial number
ETH2 serial number plus the uppercase suffix "-ETH2"
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 Legrand PDU is set to the bridging mode.
Important: In the bridging mode, only the IP parameters of the BRIDGE interface function. The IP parameters
of ETH1/ETH2 and WIRELESS interfaces do NOT function.
