Arris CMTS 1000 CRC errors


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.


Take a look here:

Still looking


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:

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.
