I was interested in knowing what percentage of the the users in this forum, provisioin their cable modems and or eMTAs in one or the other way mentioned below:
1. Specify the cable modem and emta config file in their DHCP Server config or Reservation.
2. Just specifying the TFTP file server name in the DHCP and allowing the CM or eMTA to pickup their respective MAC.xx file from the TFTP server.
Comments on why you choose the way would be a greatly appreciated.
Thanks

I don't understand the question. If you don't communicate the configuration filename via DHCP, how is the CM supposed to know which file to download?

I totally agree with you and CableLab docs clearly mention that. However someone I know kept inststing that the CM does not need a filename to bootup and the filename can be handed to it through SNMP once it has establish IP connectivity.
I was not able to get my Arris tm502 working without a valid file name in DHCP and file on the TFTP server waiting for it.
With Arris Modems, there is a proprietary option to always use the mac address as the mta config name. This info goes in the modems config, and allows you to not to specify a filename in the MTA's DHCP response. Not terribly useful but it does exist. BTW that is only for SIP Firmware, I believe. MTA's not conforming to Packetcable (i.e. Arris SIP) are free to do as they like, since the packetcable SIP spec is not done/in use.
Hi,
I m looking for some help to boot an eMTA, generate and download config files, and generate a test call from line1 to line2 within the same eMTA using TCL.
Please reply if you have the knowledge and interested in short term contract.
Thank you.
Hi
In addition to the IP that is served to the modem, the DHCP server (can) also provide other info
to the modem:
- boot file name
- tftp server ip: i.e. where the aforementioned file can be found
- time of day server ip address

Hi,
We are a small company. Out of necessity, I wrote our own stuff. It's all based on Linux. There is a little (free) utility that lets us configure our own cable modem config files. We use a Linux TFTP server to send the files to the cable modems via DHCP. Just reply if you need more help.
Thanks,

Do you manually configure DHCP? Is your DHCP server Linux DCHPD daemon?
What does your application do? What is the manual part and what is the automated part?
