Then, the frames destined for Host A are always sent out of port A. To improve the security for Host A, manually configure a static entry to bind Host A to port A.

If the retrieved address does not exist in the table, it is added. Dynamic: Dynamic entries are automatically added to the table through a process called MAC learning, in which the switch retrieves the source MAC address (and VLAN ID, if present) of each Ethernet frame received on a port.Static entries remain active until they are removed by the switch administrator. Static entries have higher priority than dynamic entries. Static: Static entries are manually added to the table by a switch administrator.The MAC address table can contain two types of entries: The table enables the switch to send outgoing data (Ethernet frames) on the specific port required to reach its destination, instead of broadcasting the data on all ports (flooding). Select Advanced, and your wireless network card's MAC Address should appear here.The MAC address table is where the switch stores information about the other Ethernet interfaces to which it is connected on a network.The value against this field is your MAC Address.Your MAC Address should be in this format: 00-14-22-04-25-37.The value displayed next to it is your MAC Address.
