Question:
What does this EEM applet event accomplish?
“event snmp oid 1.3.6.1.3.7.0.9.5.3.1.2.9 get-type next entry-op gt entry-val 75 poll-interval 5”

  • A. Upon the value reaching 75%, a SNMP event is generated and sent to the trap server.
  • B. It reads an SNMP variable, and when the value exceeds 75%, it triggers an action.
  • C. It issues email when the value is greater than 75% for five polling cycles.
  • D. It presents a SNMP variable that can be interrogated.

Explanation: EEM offers the ability to monitor events and take informational or corrective action when the monitored events occur or reach a threshold. An EEM policy is an entity that defines an event and the actions to be taken when that event occurs. There are two types of EEM policies: an applet or a script. An applet is a simple form of policy that is defined within the CLI configuration.
To specify the event criteria for an Embedded Event Manager (EEM) applet that is run by sampling Simple Network Management Protocol (SNMP) object identifier values, use the event snmp command in applet configuration mode.
event snmp oid oid-value get-type {exact | next} entry-op operator entry-val entryvalue
[exit-comb {or | and}] [exit-op operator] [exit-val exit-value] [exit-time exit-timevalue] poll-interval poll-int-value
+ oid: Specifies the SNMP object identifier (object ID)
+ get-type: Specifies the type of SNMP get operation to be applied to the object ID specified by the oid-value argument.
– next – Retrieves the object ID that is the alphanumeric successor to the object ID specified by the oid-value argument.
+ entry-op: Compares the contents of the current object ID with the entry value using the specified operator. If there is a match, an event is triggered and event monitoring is disabled until the exit criteria are met.
+ entry-val: Specifies the value with which the contents of the current object ID are compared to decide if an SNMP event should be raised.
+ exit-op: Compares the contents of the current object ID with the exit value using the specified operator. If there is a match, an event is triggered and event monitoring is reenabled.
+ poll-interval: Specifies the time interval between consecutive polls (in seconds)
