Does anybody knows how to correctly interpret the value of docsIfCmtsStatusEqualizationData (.1.3.6.1.2.1.10.127.1.3.3.1.8)?

uBR 7246 and 3com sharkfin modems

Forums: 

Me and my team just finished a transition from 3com CompleteControl CMTS to a new Cisco uBR 7246. Everything was going well until we noticed that our 3com Sharkfin Homeconnect modems weren' coming up. Well, they started coming up, one by one, still some down, but there is a problem during downloads. The modems themselves are dropping packets and never reaching their provisioned speed.

Help packetcable

Forums: 

Hi, i've been trying to provisioning a sbv5120 with no luck so far. i'm using isc-dhcpd and i think i'm sending the corrects options to the cm (option 122: 1,2) and mta (option 122: 3,6). i'm testing the basic provisioning for packetcable. the cm seems to provision ok (docsis 1.1) but the mta just keeps asking and asking for a reply, never acknowledges. i monitor the communication with dhcpdump and i'm delivering everything it asks! or so i think.
i've been googling around and tested everything i've found. could someone give me a hand? kind regards.

TFTP Across Subnets CMTS 1000

Forums: 

I am an Admin for a small Cable ISP. We have grown to a point where we need another block of IP addresses for our cable modems. Our modems, CMTS and TFTP Server run on a private IP block 172.31.1.1-254. Now that we need another block of IPs I am somewhat stumped as to where to make the changes to accomodate the new block.

Problem:

Two different Subnets over one modem

Forums: 

Hello,
We are providing a village in Austria (Europe) with cable internet.

We are looking forward to set up following situation.
We want to tell the headend (3com), that over one cable modem two different computers should be provided with to different subnets.
Computer a should get an ip with 194.208.52.x with the gateway 194.208.52.1 and computer b should get 192.168.5.x with the gateway 192.168.5.1

Both computers should work behind the same modem and should get different ip nets.

Problems with tftp config files

Forums: 

sorry for my English, I am of Argentinean and I have difficulties with the language.
I have a problem, the cable modems takes the configuration file they get up but when I prove the speed it doesn't correspond with the limitations of speed of the files in the tftp, example next

Clients/Hosts send DHCPREQUEST to DHCP Server continualy.

Forums: 

Hello! Here is DHCP Server's MRTG below:

You can see that the DHCP server traffic is bursting to 700Kbps since 140Kbps before! I has found several CPEs which in abnormal status(Sending DHCPREQUEST continualy), but I don't know how to resolve this case.

Before posted this message, I had tried reseting CMs what these abnormal CPEs belong to and restarting DHCP daemon several times, but it's no work!
Does anyone tell me kindly what should I do next ?
:(
