Docsis chat

I was reading in a whitepaper that it may be possible to pull the return spectrum data kind of like you can get from the modems for the forward through Full Band Capture.

Does anyone have any information regarding how you would do this?

Also, I have cobbled together my own code to poll/parse/display the full band capture data but have had to do so without any real documentation whatsoever, so if anyone has anything related to that as well, I would greatly appreciate it.

Thanks!

Hi

I ask for help to have OID snmp to change wifi password in cable modem cisco DPC3825

regards

Why would modems have low TX power if the return path has correct levels?

One of our nodes is experiencing a lot of issues with upstream performance. Modems on that node report good downstream RX power +/- 3dB, but upstream TX power is around 35dB. Majority of modems are Cisco DPC3825 and CMTS is a BSR 64k. SNR for the upstream channels on that node is very poor - hovering around 25dB.

Hi

Please help me, I want to graph the percentage of use of the downstream and upstream channels of a CMTS C100G Casa Systems

What are the snmp OIDs to graph

show docsis upstream channel utilization
show docsis downstream channel utilization

Certain cable modems will be unavailable from Cisco 10k CMTS. In principle, they are online, but they cannot be pinged, they do not respond to ip. However, if I try to "ping docsis MAC_ADDR", there will be an answer. After a modem restart, the tcp connection starts, but it only works for 10-20 minutes. :( Mostly affects modems, Arris type. If I replace cable modes with another one in the same place, it will work. :( What can cause such an error?
Regards!

Hey all,

Looking for best practices in modem config files. I have a couple of questions.

I want to play with the following ds/us rates and their max traffic burst. What percentage is max traffic burst typically over sustained and does anyone have an easy to understand explanation for it?

50 downstream
MaxRateSustained 50000000;
MaxTrafficBurst 8092000;
5 upstream
MaxRateSustained 5300000;
MaxTrafficBurst 4096000;

what would 100/10, 200/20, and maybe even a testing one 300/50 look like with sustained versus burst?

Hello,

I'm looking for an OID to monitor the active cm count on the upstream bonded interfaces in the Ubr10k (12.2(33)SCF3). Could someone please let me know if this exists?.

At this moment I'm using cdxIfUpChannelCmActive from ciscoDocsExtMIB for non-bonded interfaces and it's working ok but it's not showing the bonded interfaces.

Thanks in advance,

Hi guys
after the cable vendor replace the amplifier im having many pack-drops.
this is my docsis 3.0 modem stats:

hello engineers
I have a problem with my cmts cisco xvr1740 and it is the following ..
