SNMP trap parameters

You might need to know the parameters used to create SNMP traps.

• The var parameter
  The var parameter associates a user-defined trap name (specified by the trapname variable in the snmp traps command or Trap Name in FilerView) with a specific MIB object. The MIB object is specified in the value field of the snmp traps command. It must be of the form snmp.oid, where oid is an Object Identifier (OID).
• The trigger parameter
  The trigger parameter specifies the type of triggers that you can set for a trap. If a trap is triggered, data about the event that caused the trigger is sent to the network management stations.
• The edge-1 and edge-2 parameters
  The edge-1 and edge-2 parameters of a trap specify the threshold values that are compared during trap evaluation to determine whether to fire a trap and send data.
• The edge-1-direction and edge-2-direction parameters
  The edge-1-direction and edge-2-direction parameters let you set or change the direction that is used to evaluate a trap. The edge-triggered traps only send data when the edge is crossed in either the up or down direction.
• The interval parameter
  The interval parameter is the time, in seconds, between evaluations of a trap.
• The interval-offset parameter
  The interval-offset parameter is the amount of time, in seconds, until the first trap evaluation.
• The rate-interval parameter
  The rate-interval parameter specifies the time, in seconds, in which the change in value of a trap's variable (rate of change) is expressed.
• The backoff-calculator parameter
  The backoff-calculator parameter enables you to change the trap evaluation interval for a trap after a trap fires.
• The backoff-step parameter
  The backoff-step parameter specifies the number of seconds by which the trap evaluation interval is increased.
• The backoff-multiplier parameter
  The backoff-multiplier parameter specifies the value by which to multiply a trap's evaluation interval each time it fires.
• The priority parameter
  The priority parameter sets the priority of a trap.
• The message parameter
  The message parameter specifies a message that goes out with a trap.
