XG0448 can learn up to 32000 entries of MAC addresses.
• Dynamic MAC address learning
The device dynamically learns MAC addresses from received frames. If MAC addresses are not refreshed before the
aging time expires, they will be removed frame MAC address table.
To disable the dynamic learning, carry out the following procedures in "admin" Operation mode.
