Docsis chat

I've run into this odd problem twice now, wondering if anyone else has seen a similar problem.

In both instances the following is common;
Problem only occurs with DOCSIS 3 modems regardless of manufacturer, but not DOCSIS 2 or older.
CASA CMTS using cable-helper (A 2200 and 3200)
Windows DHCP Server (Windows 2000, and 2003)

I have identical configurations with Linux DHCP servers that do not experience this problem.

I have a uBR7225VXR with 2 uBR-MC88V line card, and i want to configure it 16 downstreams bonding. anybody can help me?

I've a doubt about the possibility to configure a UBR10k (PRE2 + 4x MC5x20) and RFGW-1 EQAM. I would like to configure two nodes with 8DS each (16DS in total) exclusively from the RFGW, so we will use the US from the MC5x20 LC and 16 DS from RFGW, no DS will be used on LC. Is this possible ? How could I adapt actual config. (attached) to achieve such configuration ?

Thnks,C.

we have CMTS Arris C4 (2x16D 6x12U). frequency distribution, fiber-node and supervision:

Someone have a CM config file to the L2VPN with ubr10k?

Tks

Hello,
being new in HFC network and DOCSIS world, I was wondering if there is a way to assign to CMs IPs form different pool of addresses based on different locations in a HFC network.
More specific: we have a CMTS with an external DHCP attached to a HFC distribution network. For troubleshooting purpose I would like creating pool of address for each specific location (subnetting) and have CMs assigned an IP address based on the location where they are. That would make my life easier to detect the location of a faulty CM in the network.

Thank you for your help.

I'm looking for Cisco UBR-MC88V (new/used) cards. Where I can buy in EU?

Hello everyone,

We are using ubr7246 with MC28 card. We would like to use docsis 3 cable modem, because our provider can't feed us with docsis 1. I or docsis 2.0 capable. I know we can use them easier on 1 channel like a docsis 1 cable-modem.

How can we do that ? I'm using the config file in the ubr7246 for cable-modem config. like the example below.

There is the config example we using for docsis 1 cable modem, but seem to doesnt work on docsis 3 cable modem.

Hi Everybody

I have a Motorola BSR1000 CMTS and i use a linux provisioning server made for me, the problem is when the cable modem is online use all bandwidth available, the cable modem had configured in dhcp server with a binary file with 512kbps download/upload, but what can be doing this issue?

my server is Ubuntu Server 12.04 Lts and i have a http redirection with squid3 transparent proxy, where i redirect the http connections to port 3128

Thanks for your Help

Hello,

I have a CMTS with MC88V linecard, which have activated 2 DS's and 4 channels on each DS. the DS's are seperated in the RF part. so i use the same frequency channels on both DS's.
