Configuring Global Settings 3-3
Setting the Dynamic Host Control Protocol (DHCP) Server
Use the following command to configure a PortMaster product to forward a DHCP
request from a cable modem to the DHCP server:
Command> set dhcp server address
Note – The ComOS does not support DHCP requests over Ethernet (nor requests from
PortMaster OR-U dial-up routers).
How the Cable Modem Telephone Return System Works
After you set the IP address of the DHCP server on the PortMaster product, the cable
modem dynamically configures itself so that all subsequent data travels upstream via the
telephone interface, and downstream on the coaxial cable.
Figure 3-1, using sample IP addresses, illustrates the series of events that begin upon
startup and culminate in the dynamic configuration of the cable modem.
