This command sets the Option-82 Circuit ID for a given service subscription identified by subscription-string on a given interface. The subscription-string is a character string which needs to be matched with a configured DOT1AD subscription string for correct operation. When circuit-id is enabled using this command, all Client DHCP requests that fall under this service subscription are added with Option-82 circuit-id as the incoming interface number.
