Module: SNMPv2-MIB

OID (numeric): 1.3.6.1.2.1.11.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description:
The total number of community-based SNMP messages (for example, SNMPv1) delivered to the SNMP entity which represented an SNMP operation that was not allowed for the SNMP community named in the message. The precise conditions under which this counter is incremented (if at all) depend on how the SNMP entity implements its access control mechanism and how its applications interact with that access control mechanism. It is strongly RECOMMENDED that the documentation for any access control mechanism which is used to control access to and visibility of MIB instrumentation specify the precise conditions that contribute to this value.
What is snmpInBadCommunityUses?
This is a running count of SNMP requests using a valid community name but attempting operations that the community is not permitted to perform (for example, a write attempt with a read-only community). Network engineers use it to monitor for unauthorized configuration attempts or to debug overly strict access control policies. This counter rising might mean an admin is using the wrong credentials to modify settings.
