Docsis chat

Hi,

I am trying to understand how the MIB 'docsifcmstatusresets' work. When I looked at this MIB property it has a description as 'Number of times the CM reset or initialized this interface'.

This is how I tested to see if the MIB 'docsifcmstatusresets' increments its counter with each reboot:-

1. I rebooted my cable modem through the MIB object 'docsdevresetnow'.

2. Then I checked the value of 'docsifcmstatusresets'. The value was zero.

3. I repeated step 1 few times and I found that the value of the 'docsifcmstatusresets' remained zero.

Hi,

Been trying to put bpi+ plus docsis 1.1 working. I´m getting the following error in debug. Am I supposed to install the vendor modem certificate? How do I do that?

TIA,
Rui

Hi all!

Can someone explain me a litle bit how can use and configure spectrum managment on BSR2000, maybe if smone have some kind of documentation with some examples or link to it.

Thx for help.

Hi,

As title says, I am trying to setup docsis 1.1 w/ bpi+ using a uBR7246VXR (NPE-G1) w/ 1GB RAM and IOS UBR7200-IK8S, 12.3(9a)BC9 fc1 and a webstar Euro DOCSIS modem.
That said, I´ve already tried several setups, put DOCSIS 1.1 and DOCSIS 1.0+bpi to work but have not been successful putting together DOCSIS 1.1 w/ bpi+.

Does anybody know, how we can specify direction (inbound or outband) of filtering with LLC filters in CM config file or in CMTS? We have created these filters in our config files:

SnmpMibObject docsDevFilterLLCUnmatchedAction.0 Integer 1; /* discard */

SnmpMibObject docsDevFilterLLCStatus.105 Integer 4; /* createAndGo */
SnmpMibObject docsDevFilterLLCIfIndex.105 Integer 0 ; /* All Interfaces */
SnmpMibObject docsDevFilterLLCProtocolType.105 Integer 1; /* ethertype */
SnmpMibObject docsDevFilterLLCProtocol.105 Integer 34915 ; /* PPPoE PADI 8863 */

Hello,
I have a BSR2000 CMTS, the US modulation is 64 QAM.

I have the next CM per channel:


VN-BSR2K#show cable modem s t
Interface Total Active Registered SpecGrp Group
Modems Modems Modems Name Id
Cable 0/0/U0 277 0 250 d0-u0 0
Cable 0/0/U1 144 6 128 d0-u1 0
Cable 0/0/U2 370 3 328 d0-u2 0
Cable 0/0/U3 295 0 270 d0-u3 0

Hey everyone,
Im just about gone nuts, bugeyed and drive to smoke twice as much over Arris TM402 eMTA modems.
We have approximately 150 of these units which we're purchased refurbs, GREAT cable modme, no issues, the eMTA = STRAIGHT from Hell.

Let me preface this with the fact I am not a Docsis Engineer, I just stayed in a Holiday Inn Express last night.

We provide internet services to apartment complexes, with fairly small cable plants (our largest is 150 modems). We continue to have issues at all of our sites, which I blame on plant configuration due to nobody knowing how to configure a Docsis plant. One very common issue we are facing is high levels of noise.

Here are our current settings:

Downstream:
QAM 256
Interleaver depth: 32
frequency: 747 MHz

Upstream:
QPSK - 2560K
Channel 1 freq: 40 MHz

Hello group...
I'm trying to get firmware and cert files for DCM-305 and think 301. I've got others in case you need them or trade lol
not like baseball cards, but just can't find it for those modems and need it to run some tests in my lab

Thanks in advance

Carl

Hi community,

Does anyone of you have any information/CLI commands on how to debug a Terayon 3200 CMTS?

The problem is, sometimes the CMTS looks like it puts on a CPE filter (which is not configured anywhere) and it blocks IP packets towards the CPEs on higher ports (i.e. dport > ~5000). Anyone have a similar issue or know how to do some sniffing/packet tracing on the CMTS?

Any help much appreciated...

Regards, b
