This MIB module is for configuration of the MAC notification feature. MAC notification is a mechanism to inform monitoring devices when there are MAC addresses learnt or removed from the forwarding database of the monitored devices.
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
Indicates whether the MAC notification feature is currently running in the device.
Setting this object to false(2) disables the MAC notification feature globally thus disabling the feature at each interface.
Setting this object to true(1) will start the MAC notification feature running in the device. If the feature is already running, setting to true(1) has no effect. Once the MAC notification is enabled, whether the feature is running at each interface is controlled by the cmnIfConfigTable.
cmnNotificationInterval
1.3.6.1.4.1.9.9.215.1.1.2
Unsigned32 · seconds
This object specifies the maximum interval of time between cmnMacChangedNotifications being generated by the device. If the value of cmnNotificationsEnabled is true(1), the device will send out the generated cmnMacChangedNotifications and archive the MAC change notification events in the cmnHistoryTable. If the value of cmnNotificationEnabled is false(2), the device will not send out the generated cmnMacChangedNotifications but it will archive these events in the cmnHistoryTable.
If the value of this object is equal to 0, the device will generate cmnMacChangedNotifications and archive the MAC change notification events in the cmnHistoryTable as soon as there is MAC address learnt or removed by the device.
If the value of this object is greater than 0, the device will wait for a period of time equal to the value of this object before generate the cmnMacChangedNotifications and archive the MAC change notification events in the cmnHistoryTable.
