What Is EVENT-ACTIONS-MIB?

EVENT-ACTIONS-MIB is a Cabletron Systems proprietary MIB (built on CTRON-MIB-NAMES, extending the standard RMON-MIB event mechanism) defining SET-operation actions to execute when an RMON event fires. Its action table, keyed by index, records the target object's base OID, the value to SET, operational/admin status, a description, and an execution order, while an extension table adds further OID/value pairs (extension ID, OID, value, operational/admin status) for multi-step actions. As a configuration MIB it lets an administrator define an automated remediation action (an SNMP SET to a specific object) that fires automatically when a monitored RMON threshold is crossed. It is deployed on Cabletron Systems equipment with RMON event/action support. Engineers can download the EVENT-ACTIONS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EVENT-ACTIONS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cabletron Systems equipment (RMON event/action support)

Monitoring Examples

An administrator configures ctActionObjectBase and ctActionValue to automatically disable a port via SNMP SET when a specific RMON event fires on Cabletron Systems equipment.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ctActionDefn	1.3.6.1.4.1.52.4.3.4.1
ctEventActionTable	1.3.6.1.4.1.52.4.3.4.1.1		not-accessible	This table defines actions that may take place when a given RMON event is triggered. Where action is defined as a collection of snmp SET operations to defined objects. A SET operation is defined by an OID and by a value. It is assumed that the type of the object is an integer.
ctEventActionEntry	1.3.6.1.4.1.52.4.3.4.1.1.1		not-accessible	Describes a particular action, SET operation.
OID ctActionObjectBase	1.3.6.1.4.1.52.4.3.4.1.1.1.1	OBJECT IDENTIFIER	read-only	This defines the base OBJECT IDENTIFIER that will be used for the set operation.
INT ctActionValue	1.3.6.1.4.1.52.4.3.4.1.1.1.2	INTEGER	read-write	The value that will be used in the set operation that is defined by this action entry.
INT ctActionOperStatus	1.3.6.1.4.1.52.4.3.4.1.1.1.3	INTEGER	read-only	The current operational status of the action. A value of enable(1) reflects that the action has been enabled but has never executed. A value of disable(2) reflects that the action has been disabled. A value of normal(4) indicates that the action has executed and has completed normally. A value of error(5) indicates that the action has executed but an error was detected during the operation. Possible causes are bad value, bad type of value, object out of view, incorrect object extensions as defined in ctActionObjectTable. A value of invalidExtension(6) reflects that this action can not be executed since one or more of the defined extensions are in error.
INT ctActionAdminStatus	1.3.6.1.4.1.52.4.3.4.1.1.1.4	INTEGER	read-write	Defines the desired state for this particular action entry. An action may be enabled by setting a value of enable(1) When enabled an action will execute whenever the specified event is generated. An action may be disabled by setting a value of disable(2). When disabled a given action will not be executed when the specified event is generated. However the action remains valid to be enabled later.
STR ctActionDescription	1.3.6.1.4.1.52.4.3.4.1.1.1.5	DisplayString	read-write	This text string allows the end-user to provide a description of the action; it must not contain anything but printable ASCII characters.
INT ctActionOrder	1.3.6.1.4.1.52.4.3.4.1.1.1.6	INTEGER	read-write	The value of this object controls the order of operations of actions associated with a given event. Actions with lower ctActionOrder value shall be executed first. It is not manditory that this object be set by the NMS. The default action on creation of an action entry is to create this object with a value of 1. All entries with the same ctActionOrder value will be executed in lexicographical order thus allowing for the preservation of the old order of execution.
ctActionExtensionTable	1.3.6.1.4.1.52.4.3.4.1.2		not-accessible	This table defines extensions to the action table. Extensions are in the form of get requests. The value of which appended to the ctActionObjectBase. Values are appended in sequential order as defined by ctActionExtensionID.
ctActionExtensionEntry	1.3.6.1.4.1.52.4.3.4.1.2.1		not-accessible	Defines a particular action object extension entry.
INT ctActionExtensionID	1.3.6.1.4.1.52.4.3.4.1.2.1.1	INTEGER	read-only	Uniquely identifies a specific action extension.
OID ctActionExtensionOID	1.3.6.1.4.1.52.4.3.4.1.2.1.2	OBJECT IDENTIFIER	read-write	Defines the OBJECT that will be read to get the value that will form the extension.
INT ctActionExtensionValue	1.3.6.1.4.1.52.4.3.4.1.2.1.3	INTEGER	read-only	The result of the read operation.
INT ctActionExtensionOperStatus	1.3.6.1.4.1.52.4.3.4.1.2.1.4	INTEGER	read-only	The current operational status of the action extension. A value of enable(1) reflects that the extension has been enabled but has never executed. A value of disable(2) reflects that the extension has been disabled. A value of normal(4) indicates that the extension has executed and has completed normally. A value of error(5) indicates that the extension has executed but an error was detected during the operation. Possible causes are bad value, bad type of value, object out of view, incorrect object extensions as defined in ctActionExtensionTable.
INT ctActionExtensionAdminStatus	1.3.6.1.4.1.52.4.3.4.1.2.1.5	INTEGER	read-write	Defines the desired state for this particular action extension entry. An extension may be enabled by setting a value of enable(1) When enabled an extension will execute whenever the specified event is generated. An extension may be disabled by setting a value of disable(2). When disabled a given extension will not be executed when the specified event is generated. However the extension remains valid to be enabled later.
INT ctEventActionTableEntries	1.3.6.1.4.1.52.4.3.4.1.3	INTEGER	read-only	The number of active entries in the ctEventAction Table.
