Description

topologyChange

1.3.6.1.2.1.17.0.2

A topologyChange trap is sent by a bridge when

 

 

any of its configured ports transitions from the

 

 

Learning state to the Forwarding state, or from

 

 

the Forwarding state to the Discarding state.

 

 

The trap is not sent if a newRoot trap is sent for

 

 

the same transition.

SNMPv2 Traps

 

 

 

 

 

coldStart

1.3.6.1.6.3.1.1.5.1

A coldStart trap signifies that the SNMPv2

 

 

entity, acting in an agent role, is reinitializing

 

 

itself and that its configuration may have been

 

 

altered.

warmStart

1.3.6.1.6.3.1.1.5.2

A warmStart trap signifies that the SNMPv2

 

 

entity, acting in an agent role, is reinitializing

 

 

itself such that its configuration is unaltered.

linkDowna

1.3.6.1.6.3.1.1.5.3

A linkDown trap signifies that the SNMP entity,

 

 

acting in an agent role, has detected that the

 

 

ifOperStatus object for one of its

 

 

communication links is about to enter the down

 

 

state from some other state (but not from the

 

 

notPresent state). This other state is indicated

 

 

by the included value of ifOperStatus.

linkUp

1.3.6.1.6.3.1.1.5.4

A linkUp trap signifies that the SNMP entity,

 

 

acting in an agent role, has detected that the

 

 

ifOperStatus object for one of its

 

 

communication links left the down state and

 

 

transitioned into some other state (but not into

 

 

the notPresent state). This other state is

 

 

indicated by the included value of ifOperStatus.

authenticationFailure

1.3.6.1.6.3.1.1.5.5

An authenticationFailure trap signifies that the

 

 

SNMPv2 entity, acting in an agent role, has

 

 

received a protocol message that is not

 

 

properly authenticated. While all

 

 

implementations of the SNMPv2 must be

 

 

capable of generating this trap, the

 

 

snmpEnableAuthenTraps object indicates

 

 

whether this trap will be generated.

RMON Events (V2)

 

 

 

 

 

risingAlarm

1.3.6.1.2.1.16.0.1

The SNMP trap that is generated when an

 

 

alarm entry crosses its rising threshold and

 

 

generates an event that is configured for

 

 

sending SNMP traps.

fallingAlarm

1.3.6.1.2.1.16.0.2

The SNMP trap that is generated when an

 

 

alarm entry crosses its falling threshold and

 

 

generates an event that is configured for

 

 

sending SNMP traps.
