Chapter 3: Additional PDU Information
Reserving IP Addresses in DHCP Servers
The PDU uses its serial number as the client identifier in the DHCP request. Therefore, to successfully reserve an IP
address for the PDU in a DHCP server, use the PDU's serial number as the unique ID instead of the MAC address.
Since all network interfaces of the 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
ETHERNET (PDU)
serial number
WIRELESS
serial number plus the uppercase suffix "-WIRELESS"
You can reserve the IP addresses of more than one interfaces in the DHCP server if preferred.
Reserving IP in Windows
To reserve the IP address of any network interface in the Windows DHCP server, you must convert that interface's client
identifier into
hexadecimal
ASCII codes.
For each interface's client identifier, see
Reserving IP Addresses in DHCP Servers
In this example, it is assumed that the PDU serial number is PEG1A00003.
Windows IP address reservation example:
1.
Convert the client identifier of the desired network interface into ASCII codes (hexadecimal).
Interface
Client identifier conversion
ETHERNET (PDU)
PEG1A00003 = 50 45 47 31 41 30 30 30 30 33
WIRELESS
PEG1A00003-WIRELESS = 50 45 47 31 41 30 30 30 30 33 2D 57 49 52 45 4C 45 53 53
The suffix comprising the dash symbol and the word "WIRELESS" is also converted.
2.
In your DHCP server, bring up the New Reservation dialog, and separate the converted ASCII codes with spaces.
For example, to reserve the IP address of the ETHERNET or ETH1 interface, enter the following data in the dialog.
Field
Data entered
IP address
The IP address you want to reserve.
