Docsis chat

Hello,
My goal is to increase bandwidth availabe to users from certain time of day (for example to increase transfer from midnight). Afaik its possible to achieve this thing without the need to reset cable modems by creating additional service flow with increased MaxRateSustained parameter. However i do not know how to make the transition from normal traffic flow during the day to the increased one. Do i need special classifier or is it done on CMTS? I have Arris C3 CMTS and for provisioning ISC DHCP, TFTP Server on Debian. Thanks in advance for help and sorry for my english.

Regards

Hello,

how can i set a Quality of Service(QoS) policy to preserve the voip traffic on my docsis network?

I have a Motorola BSR2000 CMTS, Cable Modems Motorola SB4200, and for provisioning ISC DHCP, TFTP Server on Centos 5.2...

thanks in advanced...

Hello All,

I'm setting up a C3 with a Debian linux server and its dhcp server. I have cable modems on the C3 that will not get past the init(o) state. I believe that means that the cm cannot get a config file from the tftp server. my syslog shows this:

Jul 20 11:33:47 benchmark dhcpd: DHCPDISCOVER from 00:0a:73:f6:d8:77 via 10.5.1.2
Jul 20 11:33:48 benchmark dhcpd: DHCPOFFER on 10.5.1.4 to 00:0a:73:f6:d8:77 via 10.5.1.2
Jul 20 11:33:50 benchmark dhcpd: DHCPREQUEST for 10.5.1.4 (10.1.1.1) from 00:0a:73:f6:d8:77 via 10.5.1.2

I am new to this Docsis technology and my company wants to inject internet and voip in CATV. I therefore need a small CMTS for testing before spending tens of thousands of dollars on the larger one that will supply atleast 20000 clients. So, can someone advise me where to get a cheap CMTS for my tests. Thanks to all.

Does anyone have any type of comparison data on all the DOCSIS provisioning systems? I cannot find anything in Gartner or Forrester. Any help would be greatly appreciated.

Hi, everyone

I'm seeing a whole lot of these messages in dhcp log for varios cable modems:

Jul 15 09:28:11 mynetwork dhcpd: DHCPREQUEST for 10.67.4.17 from 00:13:11:a6:96:0f via eth2
Jul 15 09:28:11 mynetwork dhcpd: DHCPACK on 10.67.4.17 to 00:13:11:a6:96:0f via eth2
Jul 15 09:28:11 10.67.4.17 CABLEMODEM[DOCSIS]:<68010100>DHCP RENEW sent - No response

It looks like DHCPACK from the dhcp server doesn't arrive on time or doesn't arrive at all. The strange thing is that when I ping the cable modem, there is no packet loss. Neither latency is high.

hi all,

need help on docsis best practice on how to filter bad tcp/udp ports. Thanks

Hi to all,

i tryed to install the docsisserver at first time on a debian (lenny) machine. After resolve the "m4 - Problem" the ./configure says that a mysql4.0.0 Server is needed. Lenny brings mysql 5.x per default. Is there a Patch, Tip, Trick etc. to brings up the docsisserver with mysql5.x?

Any ideas ?

Thanks

Hi everyone.
Searching for some information about the MTA file configuration, i can see that the MTA file configuration downloaded is wrong. Because there is a loop downloading the configuration file. I know this a NCS based MTA.
I don't believe that the problem is the DHCP server.

So i have questions:
1) How can i debug the MTA file configuration and check the point failed?.
2) What is the minimum configuration in order to provision it?
3) May some body share a MTA config example for this model?
