Add support for NEC/Nera radio equipment

Updated now. First impression is good! The device itself behaves strangely, but I can monitor the most critical parameters like radio RX levels.

I also have some Ceragon links that I would love to add support for radio RX/TX levels as well.

I will create a new ticket for that.

Added basic support in r10903.

I should say:

• derp MIBs (seem as incomplete and not very described)
• derp device snmp output.. really it is a great waste of time to understand what was meant in data.

There doesn't seem to be much in the way of the standard "easy" things we collect. There's a lot of messy stuff it takes a lot of work to collect, but there's likely not enough interest in these devices for that.

Thats a fair question.. I will get back to the vendor and see if they can do some sort of proper SNMP implementation on the device.. 

I guess the provided MIBs does not provide us with a doable workaround?

How do you get to be the person in charge of building the SNMP stack for a network device, but not know you need to implement ifTable?

The walk doesn't seem to include ifTable. Can you try to walk ifTable and see if you get any data?

MIB attached

Please make and attach additional information about the device:

• full snmp dump from device:

  snmpwalk -v2c -c <community> --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalk

  snmpwalk -v2c -c <community> --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

  If device not support SNMP version 2c, replace -v2c with -v1.

• If you have problems with discovery or poller processes, please do and attach these debugs:

  ./discovery.php -d -h <device>

  ./poller.php -d -h <device>

• additionally attach device and/or vendor specific MIB files
