2 From the Available Options list, scroll to Option 43 and select the 043 Vendor Specific Info check box.
3 Enter the Option 43 data into the Data Entry field.
The format for DHCP option 43 values are defined by RFC 2132. To enter an IP address of 192.168.1.10 into the Binary
column, you enter the data type code (01) and the address length (04), followed by the IP address in hexadecimal format.
You repeat the data type and address length codes for each address you enter.
If you do not know the hexadecimal format for a specific IP address, use an IP address converter
(dotted decimal-to-hex) available on the Internet.
For example, to add the four switch IP addresses 192.168.1.10, 192.168.2.10, 192.168.3.10, and 192.168.4.16 to Option
43, you enter the following hexadecimal numbers into the Data Entry field:
01 04 0C A8 01 0A 01 04 0C A8 02 0A 01 04 0C A8 03 0A 01 04 0C A8 04 10
The following image shows the four IP addresses entered into the Data Entry field on the Windows DHCP server.
