Module: SNMPv2-USEC-MIB
OID (symbolic): SNMPv2-USEC-MIB::usecStatsUnknownContexts
OID (numeric): 1.3.6.1.6.3.6.1.2.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The total number of packets received by the SNMPv2 entity which were dropped because they referenced a context that was not known to the agent.
What is usecStatsUnknownContexts?
This is a cumulative count of packets dropped because they specified an SNMP context that was not known to the agent. An admin uses this to detect misconfigured context names in polling tools targeting this device. For example, a poller configured with the wrong context string would increment this counter on every poll attempt.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.6.3.6.1.2.5 snmpwalk -v2c -c public <target> SNMPv2-USEC-MIB::usecStatsUnknownContexts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.6.3.6.1.2.5.1 snmpget -v2c -c public <target> SNMPv2-USEC-MIB::usecStatsUnknownContexts.1
