IP Connectivity Not Complete
Description
After completing the ranging stage, the cable modem then tries to establish IP
connectivity. In this process the cable modem obtains network connection
information and a cable modem IP address from provisioning servers located on the
network side of the CMTS interface. The cable modem accomplishes this with a
protocol called Dynamic Host Configuration Protocol (DHCP). If the cable modem
fails the establish IP connectivity stage it returns back to the scan for downstream
channel stage.
Note: For more information on this process, see Establish IP Connectivity (on page
10).
The following table illustrates the status of the front-panel LED status indicators
