3.4.1 MAC address table
The Layer 2 switch functionality allows the MAC addresses of any connected hosts to be dynamically learned and entered in the MAC address table. This functionality also allows static MAC address entries to be entered in the MAC address table.
The following table describes the maximum number of MAC addresses that can be entered in the MAC address table.

Registering the maximum capacity limit might not be possible due to hardware limitations.
When the number of MAC addresses exceeds the capacity limits, no new MAC addresses can be learned until previously learned entries are aged out. As a result, packets destined for unlearned MAC addresses will be flooded to all ports in that VLAN domain.
The maximum number of entries in the MAC address table cannot be changed by the configuration for the Switch.
