Fallback SNMP versions and counter sizes #72

I wish I don't have to manage if my host will reply correctly with 64 bits or 32 bits counter, SNMP v2 or v1.

Perhaps the SNMP Interface check script can test and failover this way :

try SNMP v2c and 64 bits Counter
if not found, Try 32 bits Counter
if not found, try SNMP v1

I know it will add some latency, but only on old platform which does not already support 64 bits counters...

You should know if it is an old platform and if you have 64 bit counters. Why then let it be recognized automatically when you can just set it directly?

Hi ! Because I use a monitoring system (Icinga) with template for many different equipments, using the same command (these scripts). No, I don't want to sort my 1200 existing routers by SNMP version and 64 bits support. I do trial and error, but have to override some host by host settings.
Even more, I don't know why, some Windows hosts doesn't provide 64bits counters...

I hope you don't have a 10 GBit interface that lacks the 64 bits ;-) Ok, maybe a switch for automatic snmp detection may be a solution. Can you create a PR?
