for these MAC addresses through the hardware, improving the forwarding efficiency. A
MAC address table too big in size may prolong the time for searching MAC address
entries, thus decreasing the forwarding performance of the switch.
By setting the maximum number of MAC addresses that can be learnt from individual
ports, the administrator can control the number of the MAC address entries the MAC
address table can dynamically maintain. When the number of the MAC address entries
learnt from a port reaches the set value, the port stops learning MAC addresses.
Follow these steps to set the maximum number of MAC addresses a port can learn:

By default, the number of
the MAC addresses a port
can learn is not limited.
Note:
If you have configured the maximum number of MAC addresses that a port can learn,
you cannot enable the MAC address authentication or port security functions on the
port, and vice versa.
