MAC Address Notification function configuration
MAC Address Notification function allows to monitor the availability of the network equipment by
saving MAC address learning history. When changes in learnt MAC addresses list occur, the switch saves
information to the table and notifies the user with SNMP protocol message. Function has configurable
parameters—the event history depth and the minimum message transmission interval. MAC Address
Notification service is disabled by default and can be configured selectively for the specific switch ports.
Global configuration mode commands
Command line request in global configuration mode appears as follows:
console(config)#
Table 5.223 —Global configuration mode commands
Command
Value/Default value
Action
[no] mac address-table
notification change
-/disabled
This command is designed for the global management of MAC
notification function. This command enables the registration
of MAC address addition/removal events to/from the switch
tables and sending event notifications.
Negative form of command (with 'no' prefix) disables the
function globally and overrides all respective settings on all
interfaces.
To ensure the proper function operation, you should
additionally enable generation of notifications for interfaces
(see below).
mac address-table
notification change
interval {
value
}
[0..4294967295]/1
The maximum time interval between SNMP notification
transmissions. If the interval value equals 0, the generation of
notifications and events saving to history will be performed
immediately right after MAC address table state change
