3.1 Provisioning the DHCP Server with the MAC Addresses

On the DHCP server, assign the cable modem’s CM MAC address with a DOCSIS Conguration File to

set modem communication options. (See Section 3.3, The DOCSIS Conguration File for instructions

on how to create a DOCSIS Conguration File).

Fig. 3-1, Locations of MAC Address Labels

Identier label

The CM and CPE MAC addresses are located in two places on the DSM3 Series and on the packing slip,

see below. The CM MAC address may be labeled as the RF MAC address on some DSM3 Series units.
