Option 82 is the Relay Agent Information Option in DHCP messages, which records
the location of DHCP Client. When the DHCP relay (or DHCP Snooping device)
receives the request, message sent from DHCP Client to DHCP Server, administrators
can add the Option 82 to locate the DHCP Client and control the security, cost, etc.
More flexible approaches to address allocation are created by the servers supporting
Option 82 in line with the IP addresses and other parameters allocation policies.
Up to 255 sub-options are contained in the Option 82. At least one sub-option should
be defined if Option 82 is defined. The current device supports 2 sub-options: Circuit
ID Sub-option and Remote ID Sub-option
Manufacturers usually fill options as needed since RFC 3046 fails to uniform the Option
82 options. As the DHCP relay device, Ethernet switch supports the extended padding
formats for Option 82 sub-options and the padding defaults are as follows:
⚫ Sub-option 1: VLAN No. and port index (port physical number minuses 1) of the
port receiving the Request message sent by DHCP Client.
⚫ Sub-option 2: bridge MAC address of DHCP relay device receiving the DHCP
Client Request message.
Sub-option 1: VLAN No. and port index (port physical number minuses 1) of the port
receiving the Request message sent by DHCP Client as follows.
Sub-option 2: bridge MAC address of DHCP relay device receiving the
DHCPREQUEST message of DHCP Client.
