Docsis chat

Hi,

I am new to docsis and trying to setup docsis_server to manage a small cable system.
I was wondering if anyone has ever come accross this message and how it can be resolved. This is the message that I am getting in the sys_log from within docsis_server:
NAK -- unknown docsis modem macaddressOfmodem

I reboot the modem and it keeps sending out this message above.

And below is the state of the modem when I run show cable modem on the CMTS. (ip and mac info left out on purpose)
Interface Prim Connect Timing Rec Ip Address Mac Address

Hi,

Has somebody experience with configuring CM's to trunk different vlan's? A little bit of help in putting me in de right direction would be appreciated a lot. What I liked to try is setting up the following configuration:
2 CM's, both connected to a cisco device, let's say a cat2960 where CM's are connected to ports that are configured in trunk mode. So a trunk is established between both catalysts. CM's are registered on the same CMTS (uBR 10K).

Thanks,
Regards

Hello Everyone,

I am looking for some direction on a problem I have.

I have a DCM-2000 CMTS with MPthrills management/provisioning system.

This is a lab testing setup and I have tested 1,000's of modems like DCM, SB4100, AMBit, 3com all Docsis 1.0/1.1

The SB5120 is 2.0 and 1.1 capable from what I see on the spec sheet. The SB5120s I am using were previously tested "GOOD"

The config file I am using is static and very basic.

My 1st question is, Does a DCM-2000 CMTS allow me to provision an SB-5120 or SB-5101 along with the other modems SB4100

Hi

thanks

In packetcable project, during the provisioning of the MTA, a configuration file which is in TLV format is downloaded. TLV 43 will contain vendor specific options. What ids the need of this vendor specific options? what type will be the value part of the vendor specific TLV 43?? What will we do with vendor specific information collected from the MTA configuration file ?

Hi guys,

Am having a few problems with my new house. We've been supplied with the above modem, and it doesn't seem to be working with my router.

I've got a linksys WRT54G/S router, and have the cable modem plugged into the internet (WAN) port on the router. I then have a wired pc running from the 1st ethernet port and 3 wireless laptops.

I'm getting no connection, and have done what I can in the linksys browser page, have changed it from a gateway to a router, but that didn't change anything. I keep hearing something about double nat
but afaik thats the gateway/router options?

Hi everybody

Have anyone experience with Terayon TJ110 Cablemodems running on a Cisco 7246VXR in Mixed Mode (Docsis 1.x and Docsis 2.0)???

When I activate the Mixed Mode, the old Modems doesn't come online anymore...

I am testing a Motorola BSR2000 to connect the modems .In the provisioning server I can not see the dhcp requests from the cmts .

Hello . I am confused about what a logging command does , I think it does 4 things
-It specifies what messages are shown in a console terminal
-it specifies the size and type of messages saved on the log of the BSR (shown with sh log)
-it specifies what messages saved on the BSR´s log are sent to a Syslog application considering the severity level
-it forwards snmp-traps to a server wich contains the application call syslog.

I have this configuration

ROUTER:8A#sh run | i snmp
snmp-server engineid local 80001375030030b8cdd60000
snmp-server context

Hi All,

i just tried the Docsis_server 3.5 on Centos 5.2.
It works fine for CM's but it needs at least 5 turns (ACK) from Server until the modem come online.
There is no log in syslog or logfile for dhcp or tftp.
I tried change to another Time-Server and TFTP-Server without sucess.
Any ideas? The modem starts reinitialisation after Ack.
It is a Thomson THG520.

Second question ist the dynamic file creation.
Is this working in this version now? Does anybody run this?
I'm missing the Config options in docsis_modem table.
There are still no docs for this version?
