There is a wayto apply os group for some devices with equal MIBs, but different vendors, for example radlan aka Russian Eltex.
But some vendors oem devices with changing oid prefix.
We have the same MIBS for this OS, but different prefix.
|OS||MIB||prefix||definition file||new definition file|
MIBS are identical (except prefix)
it will be easier to support and add new features if I can diff only this OSes, so I suggest to separate os=snr-switch and other snr products.
I attach dcn-like.patch
I also add some comments with examples for snmp to definitions.
And add test power supply detection for SNR switch
