P-971M User’s Guide

You will see IP Complete if your P-971M has successfully negotiated a DHCP connection with the CMTS and set your IP address.

You will see TOD Established (Time Of Day) if your cable operator’s time server has communicated with the P-971M to establish the current time and date used for event logging.

You will see Security Established if baseline privacy was requested in the configuration file and initialized by the P-971M.

You will see Registration Complete if your P-971M has received authorization from the CMTS to forward internet packets. Authorization must first be requested in the configuration file.

2.1.3 Boot State

When downloading the configuration file and booting, your P-971M passes through several negotiation stages with the CMTS. All communication steps: TFTP, DHCP Offer/Response, and Time Server must complete in order for the configuration to be successful. TFTP is the download protocol used to install the configuration file.

If there is a problem making a TFTP connection with your CMTS, you will see the message Waiting for TFTP. If the P-971M does not receive a DHCP offer from the CMTS you will see the message Waiting for DHCP Offer. Once the P-971M has responded to the DHCP offer it again waits for a response from the CMTS, if it does not receive a response you will see the message Waiting for DHCP Response. If the cable operator’s time server does not respond your will see the message Waiting for Timer Server. If the download and installation of the configuration file succeeds you will see the message Operational.

Your cable modem must receive an offer of a DHCP IP Address from the CMTS and respond to that offer in order to set your IP Address. First your cable modem is Waiting for DHCP Offer, if the offer is received by your cable modem it responds Waiting for DHCP Response to the CMTS. Once a response is received your IP Address is set and can be viewed under the CM IP Address section of this screen or in the Software status screen. Note that the DHCP IP Address setting must be completed successfully in order for your cable modem to download the configuration file.

2.1.4 Configuration File

This is the name of the cable modem configuration file downloaded from your cable operator’s CMTS using the TFTP protocol. This is a binary format file which must be DOCSIS 2.0 compliant (see RFC 2132 for additional information) A sample configuration file is included in the appendix.
