Docsis chat

Hi all,

I'm new to the forum so go easy on me!

I'm trying to setup a CMTS (arris C4c) which has IPv6 support, connected devices should query the backend server (an isc-dhcpd server) for an IPv6 address and both the cable modem and any connected devices (i.e CPE devices) should also obtain an IPv6 address (ideally from a different pool).

I have an issue with a Cisco 10k I support. The company is wanting to move to 8 channel bonding from 4 on the MC20x20 line card. Because the company is small the last Mac-Domain is not in use (5/0/4). I removed all interfaces from the domain so that 5/0/0 has 5 upstreams and so on. Similar to Mbowe config he has posted before. The issue I have is this. Modem locks on all 8 channels and 3 upstreams. SNR is 42-45 on all downstreams and 36 on up. Running speed test I get ~280Mbps which is all great!

Hi, someone has the CNR 7 can share me? Or some link to download?

I try to connect 2 CMTS UBR 7200 with 4 MC28U, i use CNR ver 6, the first CMTS no failure, but the second, Cable modem stays in INIT (o). In CNR the error shown in the TFTP server is:

file/tftp/1 Info Server 0 10084 Client 172.11.1.3:1689 Dropping duplicate request packet

the question is: How can I connect 2 CMTS in the same CNR?

I appreciate your valuable assistance

Config:

CPU with CNR:

IP 192.168.11.1
Gateway 192.168.11.253

CMTS 1

I was wondering, to anyone that has deployed IPv6 to their customers, how you track what address/prefix goes with which customer? If at all. Currently we specify that we keep records(for 6 mo) of which customer has which IPv4 address via dhcpd.leases. This is very easy as ISC DHCP logs the MAC address of the CM the request came from(option agent.remote-id). However IPv6 isn't the same, it logs a lot more information in octal format. Sometimes I can get the MAC address of the router doing the request but not in all cases.

We are trying to get the second voice port on Arris MTA's to work and are having difficulties. Can anyone share the relevant config portions or point to something that will help? We currently use PromptLink for provisioning and below is the additional we are using to try and get the second line to register. This is SIP to a Broadsoft server.

Hi guys,

Vecima and Arris support didn't answer my software requests for a CableVista MCV1100. The image on the system doesn't boot, saying that the CRC is incorrect or corrupt.

We also have a CGM14+ that needs software, but the CableVista software is the most important. If anyone could supply me with a copy of the latest software for these units it would be greatly appreciated.

Hi,

I have a question regarding matching certain types of modems (vendor / macadr ) in a UsPacketClass.
The purpose is to separate traffic into two serviceflows. The default serviceflow will go through one VRF and the traffic I'm trying to match through another VRF.

I can make it work by matching a specific MAC address (see below), but that would mean making A LOT of config files.
Instead I'm looking for a way to match a certain type of vendor or a mask of macaddresses.

I'm kind of stuck at this so any suggestions would be welcome

Hi,

I am using DOCSIS 3.0 CMTS, some modems are showing 2 US ,some only one.
Is there any problem with modems showing only one US? pls suggest

Aero#show cable modem fc4a.e91a.8bdd phy
MAC Address US IF DS IF Sid USPwr(dB) USSNR Timing MicroReflec DSPwr DSSNR Mode
TX RX (dB) Offset (dBc) (dB) (dB)
