Configuring Option 43 on a Juniper DHCP Server
Supported Formats
Suboption 3
Configuration Method
This example uses a Juniper switch as the DHCP server to describe how to configure Option 43 to carry the WAC's IP address of 192.168.100.1.
# set system services dhcp option 43 byte-stream "0x03 0x0D 0x31 0x39 0x32 0x2E 0x31 0x36 0x38 0x2E 0x31 0x30 0x30 0x2E 0x31" #
0x03: suboption type 3.
0x0D: suboption length. The IP address and symbols are expressed as characters. Therefore, the suboption length is the hex string converted from the number of characters in the character string 192.168.100.1.
0x31 0x39 0x32 0x2E 0x31 0x36 0x38 0x2E 0x31 0x30 0x30 0x2E 0x31: ASCII code of the character string 192.168.100.1.
Numbers 0 to 9 correspond to 30 to 39 in ASCII format, and the period (.) corresponds to 2E.
