MAC Notification

Device > Configure > MAC Notification

This dialog box displays the following data:

The following list specifies buttons in this dialog box, as well as their function:


MAC Notification Status (cmnGlobalFeatureEnabled)

Indicates whether the MAC notification feature is currently enabled on the device. Once enabled, the cmnIfConfigTable determines whether the feature is running on each interface. Setting this object to "false(2)" disables the MAC notification feature globally.


MAC Notification Interval (cmnNotificationInterval)

Specifies the maximum time interval between cmnMacChangedNotifications generated by the device. If the value of cmnNotificationsEnabled is "true(1)", the device sends out the generated cmnMacChangedNotifications and archives the MAC change notification events in the cmnHistoryTable. If the value of cmnNotificationEnabled is "false(2)", the device does not send out the generated cmnMacChangedNotifications, but it does archive these events in the cmnHistoryTable.


MAC Change Notification Status (cmnNotificationsEnabled)

Indicates whether cmnMacChangedNotification notifications are sent when MAC addresses are learned or removed from the device's forwarding database. Disabling notifications does not prevent MAC address information from being added to the cmnHistoryTable.


Number of Entries MAC Change Notification Archive (cmnHistTableMaxLength)

Upper limit on the number of entries the cmnHistoryTable can contain. A value of "0" will prevent any entries from being retained. When this table is full, the oldest entry is deleted and a new one is created.
