Docsis chat

Hi, everyone

I'm seeing a whole lot of these messages in dhcp log for varios cable modems:

Jul 15 09:28:11 mynetwork dhcpd: DHCPREQUEST for 10.67.4.17 from 00:13:11:a6:96:0f via eth2
Jul 15 09:28:11 mynetwork dhcpd: DHCPACK on 10.67.4.17 to 00:13:11:a6:96:0f via eth2
Jul 15 09:28:11 10.67.4.17 CABLEMODEM[DOCSIS]:<68010100>DHCP RENEW sent - No response

It looks like DHCPACK from the dhcp server doesn't arrive on time or doesn't arrive at all. The strange thing is that when I ping the cable modem, there is no packet loss. Neither latency is high.

hi all,

need help on docsis best practice on how to filter bad tcp/udp ports. Thanks

Hi to all,

i tryed to install the docsisserver at first time on a debian (lenny) machine. After resolve the "m4 - Problem" the ./configure says that a mysql4.0.0 Server is needed. Lenny brings mysql 5.x per default. Is there a Patch, Tip, Trick etc. to brings up the docsisserver with mysql5.x?

Any ideas ?

Thanks

Hi everyone.
Searching for some information about the MTA file configuration, i can see that the MTA file configuration downloaded is wrong. Because there is a loop downloading the configuration file. I know this a NCS based MTA.
I don't believe that the problem is the DHCP server.

So i have questions:
1) How can i debug the MTA file configuration and check the point failed?.
2) What is the minimum configuration in order to provision it?
3) May some body share a MTA config example for this model?

Good day,

Using Cisco CNR I can configure a cable modem and it gets its IP and .cm file
Behind that cable modem is a host that I want to make an ip to mac reservation and then send a file to the host right after dhcp using tftp.

this is what it would look like using a linux dhcp server (snip from dhcpd.conf)

(Note this is in a lab environment so the IP's are not public)

#!/bin/sh

Hi, everyone

Recently we've been testing a small Chineese CMTS in our network. One strange observation: MaxRateSustained in the cable modem config file is not being respected. Any cable modem can use all bandwidth the CMTS can provide for download. So, I'm a bit puzzled. Does the CMTS has anything to do with MaxRateSustained config parameter? In other word, does it has to be supported somehow in CMTS as well as in cable modem in order to work properly?

Thanks and best regards,

I need some help to set up a C3. I'm having difficulty to get the settings I want to work properly. Can someone help me out please?

Hello all,

I have a problem with the Motorola 3100,4100,4200 cable modems. Whenever the power goes out, the power cable on those cable modems need to be unplugged and plugged back in to resync. Is there a firmware upgrade that can fix this? It's a simple fix, but it would sure save a lot of phone calls every time there is a thunder storm?

Thanks,

The extrange thing is that other eMTAs works fine with the actual bin file I'm using. Any ideas ???. Thanks.-
