Chapter 4 Configuring Basic Broadband Internet Access
Typical Routing Configuration For High Speed Internet Access
• DHCP Address Pools—The Cisco uBR7111 router acts as a DHCP server, providing different
address spaces on the basis of the cable modem’s service level, including those customers whose
network access should be denied access because they have cancelled their service. Different default
pools can be used for cable modems and for the IP hosts behind them. Static IP addresses can also
be assigned to specific clients on the basis of the client’s MAC address.
• DOCSIS Cable Modem Configuration Files—These configuration files provide several different
service level options:
– platinum.cm—Users are given a maximum upstream bandwidth of 128kbps, with a guaranteed
minimum bandwidth of 10kbps. The downstream has a maximum bandwidth of 10Mbps. Up to
8 PCs are allowed on this connection.
– gold.cm—Users are given a maximum upstream bandwidth of 64kbps and a maximum
downstream bandwidth of 5Mbps. Up to 3 PCs are allowed on this connection.
– silver.cm—Users are given a maximum upstream bandwidth of 64kbps and a maximum
downstream bandwidth of 1Mbps. Only 1 PC is allowed on this connection.
– disable.cm—Users are denied access to the cable network. This configuration file can be used
for users who have cancelled service or have not paid their bills.
