Tail of SNMP Trap Log

Tail of SNMP Trap Log report reveals the n most recent SNMP trap notifications recorded (also known as the "tail") in the SNMP trap log. This report is useful for quick access to recent trap notifications which can be indicators of significant activities happening on your network.

Date. Date and time of event.
Device. Device hostname, IP address, or custom label.
SNMP Trap Type. Reflects Trap Type value in SNMP Trap Protocol Data Unit (PDU). For example: coldStart(0), linkDown(2), authenticationFailure(4), and where n>5 indicates an enterprise specific trap type.
Payload. SNMP PDU data fields.

Note: SNMP Trap listener must be enabled and either a SNMP passive monitor must be associated with a monitored device or unsolicited SNMP traps accepted. For more information, see Enabling the SNMP Trap Listener.
