LinkFlapIntfAction  
The possible actions that the Link Flap feature can take when link flap activity exceeds the associated action limits. disableInterface(0) - Operationally disable the interface, ifOperStatus for the interface MUST go into the 'down' state, and MUST remain in that state until the associated etsysLinkFlapIntfStatus is set to operational, the Link Flap feature is disabled, or the device is reset. generateSyslogEntry(1) - Generate the respective device log entry. generateNotification(2) - Generate the respective SNMP notification. The 'generateNotification(2)' will always be performed if it is a selected action, is globally enabled, and does not exceed the global rate limit for such notifications. It MUST be generated in such a way that the information in the notification indicates the condition on the interface after any other indicated action has been taken.

etsysLinkFlapSystemState 1.3.6.1.4.1.5624.1.2.52.1.1.1
The current state of the active part of the Link Flap feature. enabled (1) - All supported aspects of Link Flap are operational. disabled (2) - Link Flap is configurable but no actions are taken. All statistical information is still gathered and available. When this object is set to disabled the Link Flap feature MUST release its control on all interfaces. Any interfaces which the Link Flap feature had operationally held in the 'down' state MUST be allowed to attain their currently correct operational state. Maintaining the value of this object across agent reboots is REQUIRED.

etsysLinkFlapSystemSupportedActions 0.1.2.1.3.6.1.4.1.5624.1.2.52.1.1.2
The supported actions that the Link Flap feature can take when link flap activity exceeds the associated threshold on this interface. disableInterface(0) - Capability to set the interface operational status to 'down'. generateSyslogEntry(1) - Capability to create syslog messages. generateNotification(2) - Capability to generate SNMP notifications. Please see the LinkFlapIntfAction textual convention defined in this MIB.

etsysLinkFlapSystemLinkFlapMaximum 1.3.6.1.4.1.5624.1.2.52.1.1.3
The greatest number of linkdown events which can occur per ten second interval. This is an implementation-specific parameter which will determine the allowable values of etsysLinkFlapIntfCountThreshold and etsysLinkFlapIntfTimeInterval. Setting either one of these such that the ratio of etsysLinkFlapIntfCountThreshold to etsysLinkFlapIntfTimeInterval would become greater than etsysLinkFlapSystemLinkFlapMaximum will result in the set operation failing with an inconsistentValue error.

etsysLinkFlapInterfaceEntry 1.3.6.1.4.1.5624.1.2.52.1.2.1.1

etsysLinkFlapIntfEnabledStatus 1.3.6.1.4.1.5624.1.2.52.1.2.1.1.1
The enable state of Link Flap on this interface. Transitioning from enabled(1) to disabled(2) will disable the active part of the Link Flap feature as defined for the etsysLinkFlapSystemState object on this interface. In this event the agent MUST: 1) Release its control on this interface. If the interface had been operationally held in the 'down' state, then the interface MUST be allowed to attain its currently correct operational state. 2) etsysLinkFlapIntfOperStatus MUST be set to operational(1). 3) The objects etsysLinkFlapIntfLinkdownCountCurrent etsysLinkFlapIntfLinkdownCountTotal etsysLinkFlapIntfCurrentElapsed MUST continue to accrue value as events occur. In transitioning from disabled(2) to enabled(1) the objects: etsysLinkFlapIntfLinkdownCountCurrent etsysLinkFlapIntfCurrentElapsed MUST be initialized at 0 (zero) for this interface. Maintaining the value of this object across agent reboots is REQUIRED.

  INTEGER enabled(1), disabled(2)  

etsysLinkFlapIntfAction 1.2.1.3.6.1.4.1.5624.1.2.52.1.2.1.1.2
The configured actions that the Link Flap feature can take when link flap activity exceeds the associated threshold on this interface. disableInterface(0) - Interface operational status set to 'down'. generateSyslogEntry(1) - Descriptive syslog message generated generateNotification(2) - SNMP notification generated. Maintaining the value of this object across agent reboots is REQUIRED.
OBJECT-TYPE

etsysLinkFlapIntfOperStatus 1.3.6.1.4.1.5624.1.2.52.1.2.1.1.3
The current status of the interface with respect to Link Flap detection. A read of operational(1) indicates that the Link Flap feature has not taken any action to operationally limit this interface. A read of disabled(2) indicates that the Link Flap feature has taken action to operationally disable this interface due to excessive link state transitions. Setting this object to operational(1) when it is disabled(2) will cause Link Flap to release its control which is keeping this interface operationally disabled. Any other write of this object will have no effect. Maintaining the value of this object across agent reboots is NOT RECOMMENDED.

  INTEGER operational(1), disabled(2)  

etsysLinkFlapIntfClearStats 1.3.6.1.4.1.5624.1.2.52.1.2.1.1.4
When set to true(1) the following objects: etsysLinkFlapIntfLinkdownCountCurrent etsysLinkFlapIntfLinkdownCountTotal etsysLinkFlapIntfLinkFlapViolations in this row of the etsysLinkFlapInterfaceTable MUST be set to 0 (zero). Setting this object to false(2) will have no effect. When read this object will always return false(2). Maintaining the value of this object across agent reboots is NOT RECOMMENDED.

etsysLinkFlapIntfCountThreshold 1.3.6.1.4.1.5624.1.2.52.1.2.1.1.5
The threshold count of link state transitions, which if exceeded within time limit etsysLinkFlapIntfTimeInterval, necessitates actions specified in LinkFlapIntfAction. Setting etsysLinkFlapIntfCountThreshold such that the ratio of etsysLinkFlapIntfCountThreshold to etsysLinkFlapIntfTimeInterval would become greater than etsysLinkFlapSystemLinkFlapMaximum will result in the set operation failing with an inconsistentValue error.

Setting etsysLinkFlapIntfTimeInterval such that the ratio of etsysLinkFlapIntfCountThreshold to etsysLinkFlapIntfTimeInterval would become greater than etsysLinkFlapSystemLinkFlapMaximum will result in the set operation failing with an inconsistentValue error. Note that one special value, 0 (zero) of the etsysLinkFlapIntfTimeInterval is used to specify that etsysLinkFlapIntfTimeInterval is unbounded. Maintaining the value of this object across agent reboots is REQUIRED
