Hi I'm developing a DHCP Server for DOCSIS and Packet Cable, And I want to know the Mac-Address from the cable-modem, the problem is that in the dhcp message from CPE (computer)I just see the ip address from CMTS (Relay agent giaddr field) but I can't see the ip from the Cable Modem. How do I know the Mac-Address from Cable Modem and the Mac-Address from CMTS?
