MAC Address Table Management
The MAC address table is a database used for managing the association between address information and destination ports.
XG0224 and XG2600 can learn up to 16000 entries of MAC addresses.
XG0448 / XG0440DC / XG0440DCR 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.
To change aging time period of MAC address learning table, carry out the following procedures in "admin" Operation
mode..

Static unicast addresses are not subject to MAC address removal controlled by the aging function.
To register, change or delete a static unicast address, carry out the following procedures in "admin" Operation mode.
