linkDown linkUp authenticationFailure RisingAlarmTrap FallingAlarmTrap newRoot topologyChange A linkDown trap signifies that the 1.3.6.1.6.3.1.1.5.3 sending protocol entity recognizes a failure in one of the communication links represented in the agent's configuration. A linkUp trap signifies that the 1.3.6.1.6.3.1.1.5.4 sending protocol entity recognizes that one of the communication links represented in the agent's configuration has come up. An authenticationFailure trap 1.3.6.1.6.3.1.1.5.5 signifies that the sending protocol entity is the address of a protocol message that is not properly authenticated.While implementations of the SNMP must be capable of generating this trap, they must also be capable of suppressing the emission of such traps via an implementation- specific mechanism. This trap is an SNMP notification that 1.3.6.1.2.1.16.29.2.0.1 is generated when a high capacity alarm entry crosses its rising threshold and generates an event that is configured for sending SNMP traps. This trap is an SNMP notification that 1.3.6.1.2.1.16.29.2.0.2 is generated when a high capacity alarm entry crosses its falling threshold and generates an event that is configured for sending SNMP traps. The newRoot trap indicates that the 1.3.6.1.2.1.17.0.1 sending agent has become the new root of the Spanning Tree; the trap is sent by a bridge soon after its election as the new root, e.g., upon action of the Topology Change Timer immediately subsequent to its election. Implementation of this trap is optional. A topologyChange trap is sent by a 1.3.6.1.2.1.17.0.2 bridge when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a newRoot trap is sent for the same transition. Implementation of this trap is optional.
