Docsis chat

Hello all!
I've got what I suspect to be a simple issue here... I'm an IP network guy by trade, so forgive me if this is a ridiculous question :)

I have a CMTS with a downstream that's loaded. I have a second linecard that I'd like to activate, and have split the HFC plant (or a node, specifically) to accomodate this: I now have physically separate up and downstream paths for the node so that I can run my second linecard on that node, and run our busiest node on that card.
We run the ISC DHCP server on linux boxes behind the uBR using the cable helper-address config directive.

Help me, what I'm do not right and where mistake? dhcpd log [code] DHCPDISCOVER from 00:1a:ad:96:bf:68 via 10.15.0.1 DHCPOFFER on 10.15.0.3 to 00:1a:ad:96:bf:68 via 10.15.0.1 DHCPREQUEST for 10.15.0.3 (192.168.2.15) from 00:1a:ad:96:bf:68 via 10.15.0.1 DHCPACK on 10.15.0.3 to 00:1a:ad:96:bf:68 via 10.15.0.1 DHCPDISCOVER from 00:1a:ad:96:bf:6a via 192.168.50.1 DHCPOFFER on 192.168.50.3 to 00:1a:ad:96:bf:6a via 192.168.50.1 DHCPDISCOVER from 00:1a:ad:96:bf:6a via 192.168.50.1 DHCPOFFER on 192.168.50.3 to 00:1a:ad:96:bf:6a via 192.168.50.1

Hello,

Has anyone been successful in compiling docsis-0.9.5.tar.gz on Debian?

Thanks,

Hello,

I am using Arris C3 CMTS in the network more than one year. The machine worked well all this time. A few days a go I detect some problems with transferring of CMs config file from TFTP through this CMTS to CMs.

On C3 is 290 CMs. First approximately 210 CMs immediately download their conf file. CMs which try to connect after approximately 210 successfully registration complete CMs, they needed more than 15 min for downloading there config file. On cable modem log is the message TFTF request sent but no response received.

I have a Motorola BSR 1000 EuroDocsis 1.1. with this configuration

Hello,

I have a Arris CMTS 1500. I noticed that when I hooked it up to replace my Arris CMTS 1000 that 50 of my 85 CMs were stuck in a "Registration Request" state. After much research I determined that the 50 CMs were Ambit CMs that were docsis 2.0. I guess what I need is a CM config file that disables the docsis 2.0 stuff. Can anybody help out? Also, does anybody have a list of what the TLVs are?

Can anyone tell me what the maximum throughput of an SA Webstar DPC2100R2 is? I've read on Cisco's website that it is 43 Mbps (which should probably read more like 38 Mbps), but when configuring it for 30Mbps through my cmts, I can only get about 5Mbps. This is almost directly off of the CMTS, so I'm sure the slow down is not plant related.
Thanks in advance,
Donna

Does anyone know where I can get an overview of the maximum rates supported by the different versions of DOCSIS? I found some info on wikipedia, but not in the specifications of CableLabs.

Thanks in advance.
Cheers.

I need a sample config file for this modem.
Mostly a part of the config for VoIP lines.
If someone has it and it's realy working....
That would be realy wonderfull if you could just post it here.
It is realy an emergency!
Motorola SBV5121E.

We didn't really want to buy a CMTS is necessary, I would think there must be some kind of desktop model available for a testing lab somewhere... Thanks!
