Arris CMTS 1000 CRC errors

Hello,

Can anyone tell me the SNMP OID that identifies RF CRC errors and microreflections? I'm trying deal with customer complaints of slow Internet speeds. Bandwidth bottlenecking is usually the main cause, but I've noticed that CRC Errors really mess up speed too. Rather than telnet into the CMTS command line and type: modem state XX:XX:XX:XX:XX:XX, I'd like to just write it into my application.

Thanks,
emkowale

Still looking

Hi,

I still need a way to grab the data I need. For example, when I type:

mod state 00:15:96:6A:8D:88

I Get:

Information for modem 00:15:96:6a:8d:88

Current state: Registered

Ranging info:

I need a way (via SNMP) to read the CRC Errors ans HCS Errors. In doing so, I would be able to locate plant problems better and tell if they are subscriber home issues or plant issues. I'm just not sure where to look.

Thanks,
