Comtech CDM-IP 300L with Net SNMP

Getting eb/no status on Comtech CDM-IP 300L using SNMP is really straightforward, its easy and the only problem for me at the first time is finding the right MIB for this specific modem, and here is the link on Comtech website http://www.comtechefdata.com/flashupgrades/legacy/legacy.asp

I am downloading file Framer II under CDM-IP_550_300L_V133.

here is the step :
1. extract file CDMIP_Framer_II_133.zip.
2. copy only these 3 files, fw10174-2d.mib fw10174-4b.mib fw10174-8-.mib to Net SNMP directory on linux machine, mine : /usr/share/snmp/mibs
3. execute the command : snmpget -v2c -On -c public modemIP cdmip300LRxEbno.0 or in numeric format snmpget -v2c -On -c public modemIP .1.3.6.1.4.1.6247.6.1.7.3.0
4. The eb/no result is in numeric 3 digit format.
