Questions tagged [snmp-trap]

A trap is an SNMP message used by an Agent to notify its Manager that an event has occurred, either an error or a normal occurrence. Use this tag for SNMP related questions that concern Trap messages.

A trap is an SNMP message used by an Agent to notify its Manager that an event has occurred, either an error or a normal occurrence. Traps are often used by network management systems to detect faults or deviations in the monitored devices.

Traps are sent without expecting acknowledgement, in contrast to Inform messages. A Manager that receives an Inform message should send a reply to the Agent.

Like other SNMP messages, a trap may carry one or several Variable Bindings. The value and meaning of each variable binding is implementation specific.

A MIB document is usually available which describes both the Trap and the varbinds.
