Managing MAC Address Table Security Configurations
3.2 Using the CLI
3.2.1 Configuring MAC Notification Traps
Follow these steps to configure MAC notification traps:
Step 1 configure
Enter global configuration mode.
Step 2 mac address-table notification global-status {enable | disable}
Enable MAC Notification globally.
enable | disable: Enable or disable MAC Notification globally.
Step 3 mac address-table notification table-full-status
[enable | disable]
(Optional) Enable Table Full Notification.
enable | disable: With Table Full Notification enabled, when address table is full, a notification
will be generated and sent to the management host.
Step 4 mac address-table notification interval
time
Set your desired interval time between each set of New MAC Learned notifications that are
generated.
time:
Specify a time value in seconds between 1to 1000 to bundle the notifications and reduce
traffic. By default, it is 1 second.
Step 5 interface {[ gigabitEthernet
port
] | [ range gigabitEthernet
port-list
]}
Configure notification traps on the specified port.
port/ port-list:
The number or the list of the Ethernet port that you want to configure notification
traps.
Step 6 mac address-table notification {[learn-mode-change
enable | disable] [exceed-max-learned
enable | disable] [new-mac-learned enable | disable]}
Enable learn-mode-change, exceed-max-learned, or new-MAC-learned notification traps on
the specified port.
enable | disable:Enable or disable learn-mode-change, exceed-max-learned, or new-MAC-
learned notification traps on the specified port.
learn-mode-change: With learn-mode-change enabled, when the learned mode of the
specified port is changed, a notification will be generated and sent to the management host.
exceed-max-learned: With exceed-max-learned enabled, when the maximum number of MAC
addresses on the specified port is exceeded, a notification will be generated and sent to the
management host.
For Exceed Max Learned notification, you need to enable Port Security and set the maximum
number of MAC addresses on the specified port. For more information about Port Security,
please refer to
Managing Physical Interfaces
.
new-mac-learned: With new-mac-learned enabled, when the specified port learns a new MAC
address, a notification will be generated and sent to the management host.
Step 7 end
Return to privileged EXEC mode.
Step 8 copy running-config startup-config
Save the settings in the configuration file.
