Remote ID Suboption Frame Format:
Suboption Length Type
Type
0x02 8 0
Circuit Form:
The circuit form is a flexible architecture. It allows user to combine any information or the
system configurations into the circuit sub-option.
The Circuit Form is a string format. And its maximum length is 100 characters.
The keyword, %SPACE, will be replaced with a space character.
The other keywords get system configurations from the system and then replace the
keyword and its leading code in the Circuit form. Eventually, the content of the circuit
form is part of the payload on the DHCP option 82 packet.
Rules:

The keyword must have a leading code '%'. For example: %HOSTNAME.

If there are any characters following the keywords, you must add '+' between
the keyword and character. For example: %HOSTNAME+/.

If there are any characters before the keyword, you must add '+' between the
character and the keyword. For example: Test+%HOSTNAME.
Keyword:
HOSTNAME - Add the system name into the Circuit sub-option..
SPACE - Add a space character.
SVLAN - Add the service provider VLAN ID into the Circuit sub-option.
If the service provider VLAN is not defined, the system will return
PVLAN.
CVLAN - Add the customer VLAN ID into the Circuit sub-option.
If the CVLAN is not defined, the system returns 0.
PORT - Add the transmit port ID into the Circuit sub-option.
FRAME - Add the frame ID into the Circuit sub-option.

SHELF - Add the shelf ID into the Circuit sub-option.
The shelf ID is configured with the CLI command, "dhcp-
options option82 circuit_shelf VALUE". Or GUI Circuit
Shelf.
SLOT - Add the slot ID into the Circuit sub-option.
The slot ID is configured with the CLI command, "dhcp-
options option82 circuit_slot VALUE". Or GUI Circuit Slot.
For Example:
HOSTNAME=TI-PG1284I.
SVLAN=44.
CVLAN=32.
