What is snmpUnknownContexts?
This read-only Counter32 tallies the total number of packets received by the SNMP engine that were dropped because the context contained in the message was unknown. Admins monitor this counter to detect misconfigured management applications or proxies sending requests for a context that doesn't exist on this SNMP engine. A rising count would prompt an admin to check whether a monitoring tool is querying a stale or mistyped context name.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.6.3.12.1.5 snmpwalk -v2c -c public <target> SNMP-TARGET-MIB::snmpUnknownContexts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.6.3.12.1.5.1 snmpget -v2c -c public <target> SNMP-TARGET-MIB::snmpUnknownContexts.1
