I understand the basic use of SNMP where you manage and monitor switch, routers,etc. features using IP network. I also understand there are MIBs for SNMP based on RFCs like 2981, 3289, 3376, etc. However, recently I heard from couple of customers talking about private MIBs and it seemed like they were really interested in it.
Can somebody explain to me what are private MIBs? Why would somebody be interested in it?
Are there private MIBs equivalent for MIBs based on RFCs? For example, is there something like a private MIB for RFC 2981 MIB?
