SNMP returning strange values BSR 64K

Forums: 

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".

CPU High CMTS uBR10K

Forums: 

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?

MIB library for RFGW-1

Forums: 

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.

Dropping packets using over 4 channels

Forums: 

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.

SNR Upstream in frequencies lower than 20Mhz.

Forums: 

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)

running into issue with filter in config file

Forums: 

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.

Channel Utilization / Saturation

Forums: 

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?

Unhide and show private enterprise MIBs

Forums: 

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?

Pace and Arris firmware please

Forums: 

good morning everyone
currently have the following modems with super old firmware. some drop from 3.0 to 2.0 when I go from 24 channel to 32 channel bonding.
Does someone have newer firmware and cert files so I can do an upgrade
Pace model D5001 current firmware 1.407.2.25 (would need cert file)
Arris modem cm820A current firmware 7.5.55 (already have the cert file)
Arris modem dg860p2 current firmware 7.5.50a (already have the cert file)

best to send via wetransfer dot com my email is cmcaldas at gmail dot com
