Docsis chat

Hello,

I do not run an ISP. I am just interested in DOCSIS, and have a question about a particular scenario, so I hope that's ok. An unknown modem is plugged into the cable network with an HFC MAC address that is not from a paying customer. It gets the config file "unknownmodem.bin", which is shown at the bottom of this post.

Does anybody has deployed Wireless Docsis for VoIP and Data Support?

I am getting this error on two modems out of just over 100. The modem picks up an IP, but the CPE can't get one. I've talked to one of the customers and she says she had a router hooked up at first, but switched over to her computer. We've power cycled to modem several times, but the problem persists.

Does this sound like an issue with the DHCP config or is the modem not releasing it's CM cache?

Here is my dhcp and modem configs:

dhcp:

class "cm" {
match if substring(option vendor-class-identifier,0,6) = "docsis";
spawn with option agent.remote-id;
}

I am running a FOCS server hooked to a CC8000 cmts. I am only seeing 50 CM's get an ip and the rest are in ranging complete state. Any information on where to find the place to set a higher limit or anythign on this would be great.

Thanks,
Mark

I'm trying to pull RX power and SNR data for all registered modems off the CMTS. When I did a snmp walk of the CMTS, I noticed OID's were in place:

RX power: 1.3.6.1.2.1.10.127.1.3.3.1.6
SNR: 1.3.6.1.2.1.10.127.1.3.3.1.13

When I walk these OID's they mostly return 0 value, but an occasional one will spit out a number. Do I need to pass a filter or something in the modem config to get it to relay this info back to the CMTS?

Hello everybody,
First of all I hope I'm on a right forum to ask this question. I had my 1st cable connection today, before I've always had dsl. Everything works fine but I realized that the "cable activity" diod of the THG540 modem blinks like crazy even if do nothing on the net. I had a look at the network with tcpdump and I can see a LOT of ARP request of my ISP (Kabel Deutschland). Is this normal in the cable technology ? Since the APR packets are not routable, does it mean that I'm on a LAN of my ISP with other clients ?

Hello!

Can someone look over my dhcpd.conf config and see if it looks okay? After fighting the provisioning software we just acquired, I've decided that since we have all the customer info in database form already, that I'm just going to write my own. When subscribers are added or removed, I'm just going to have it dynamically rebuild the dhcpd.conf file from the db and upload it to the dhcp server via ftp (then restart the service).

Anyway, I just put this file together and don't have time to test it now (will in the morning) so can anyone point out any glaring errors?

I need to know if somebody has a DOCSIS1.1 file to provide QoS for rstp protocol and VOIP.

I have an odd problem I'm hoping to solve.
Is it possible to get a CM to forward the config file (it gets via tftp) to the PC sitting behind the CM?

Logged into the CM, I see that I can 'tftp put' files, so that would work. But it looks like CMs don't save their tftp config
files anywhere. Do CMs typically just parse the config file without saving it anywhere?

Thanks.
