Hello All
I've got about 600 sb6141 with original firmware on an old Cisco w/ 88v's with 8 chnl bonding. plan is to migrate to an Arris C4 with 32 channel bonding. I've had issues in the past with old 8 chnl bonding modems and wanted to get them upgraded to avoid issues.
would anyone happen to have firmware and cert file I could use?
Please let me know, cmcaldas at gmail dot com

Thank you in advance

I've built a small app our techs can use to monitor CMTS status, currently has simple things like upstream SNR, total modems online/offline, that sort of thing.

I'm trying to add a simple ping test to show online/offline and latency, but I'm getting strange results from the CMTS for mac addresses. When I query the CMTS for a list of MAC addresses, most return fine but some show up like "P9UJ%", "P9UT[", "P9UK5", "P9UMv".

dear all the time while my cmts goes from a cpu around 15% to 90% and then falls back to normal levels. in the log at the last event is the one in the attached file. cmts is a ubr10k with PRE-4 and fw ubr10k4-k9p6u2-mz.122-33.SCG6.bin. any tips to solve this ??

Hi,

does anybody have an idea what si cause for the log messages below?

Does anyone have access to or know where to find the Cisco RFGW-1 MIB library? (CISCO-RFGW-1-MIB.my)
I cant find it anywhere on the web/Cisco site and an SNMPwalk on the RFGW doesn't reveal much obvious information.
Is anyone out there monitoring these? I'm looking to monitor temperature/fans and data usage.

Got a bit of an odd one here. Have been using 16 channels using a Cisco Ubr10k w/ PRE5s (SCJ4) and 20x20 cards and there seems to be a large amount of packet loss if all 16 channels are broadcast to a node.

I'm having some issues with SNR stability in low freq.

Here's the deal:

We have 4 Upstream channels for each optical node.
Our 4 channels are in 36.8Mhz, 30.4MHz 24MHz and 17.6MHz.
We have 54 nodes that are using the 17.6MHz freq. In around 70% of those 54 nodes, we experience high noise in the 17.6MHz freq. Which results in SNR lower than 25dB.
We are having issues finding out what causes this, so we spent. around 3 or 4 days sweeping the entire node, looking for the source of noise (which usually is a faulty installation inside customers premises)

Hello all,

A little background first before I pose the question/issue. We are currently running a number of different model cable modems using a "catch-all" cm file. The modem models currently deployed on our network are Arris models: DG860, DG2470A, DG3260A, DG3270A, TM3402A, and TG3452A. The modems are set as provisioned mode docsis only as the built in telephony adapter is not utilized on our network yet. We are using a stand alone Cisco/Linksys SPA122 or SPA-2102 which connect to our sip/metaswitch environment.

Hi,

kind of silly questions, but I want to understand what is being used around your plants:

1) What is the parameter you use to consider a service group (downstream or upstream) saturated?

2) Do you measure it by peaks or average?

3) Are your node splits related to this metric?

If you answer to question 3 is "yes", how long it takes from the moment the trigger is fired to the actual physical node split?

the Cisco EPC3008, SNMP show only part of MIBs, mainly standard IETF MIBs, but private enterprises MIB entities are hidden.
Private MIBs are accessible for console commands, though. How to unhide these MIBs, to access them via standard SNMP, over UDP port?
