OID (numeric): 1.3.6.1.4.1.1166.1.31.0.26

Description: This trap is issued when an unknown message is received. The trapAdditionalInfoInteger1 will contain the task and Function ID. The trapAdditionalInfoInteger2 will contain the message ID and the trapAdditionalInfoInteger3 is not used.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' APEX-MIB::trapUnknownMessageReceived
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.1166.1.31.0.26

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:
