MAC Address Table

The MAC address table contains address information that the Switch uses to forward traffic between the inbound and outbound ports. All MAC addresses in the address table are associated with one or more ports. When the Switch receives traffic on a port, it searches the Ethernet switching table for the MAC address of the destination. If the MAC address is not found, the traffic is flooded out all of the other ports associated with the VLAN. All of the MAC address that the Switch learns by monitoring traffic are stored in the dynamic address. A static address allows you to manually enter a MAC address to configure a specific port and VLAN.

Static MAC Address

The address table lists the destination MAC address, the associated VLAN ID, and port number associated with the address. When you specify a static MAC address, you set the MAC address to a VLAN and a port; thus it makes an entry into its forwarding table. These entries are then used to forward packets through the Switch. Static MAC addresses along with the Switch's port security allow only devices in the MAC address table on a port to access the Switch.

Click the Add button to add new entry:

Item	Description
Index	Displays the index for the static MAC address table.
Port	Select the port where the MAC address entered in the previous field will be automatically forwarded.
VID	Enter the VLAN ID on which the IGMP Snooping querier is administratively enabled and for which the VLAN exists in the VLAN database
MAC Address	Enter a unicast MAC address for which the switch has forwarding or filtering information.

Click the Apply button to accept the changes or the Cancel button to discard them.

Dynamic MAC Address

The Switch will automatically learn the device's MAC address and store it to the dynamic MAC address table. If there is no packet received from the device within the aging time, the Switch adopts an aging mechanism for updating the tables from which MAC address entries will be removed from related network devices. The dynamic MAC address table shows the MAC addresses and their associated VLANs learned on the selected port.

Click the Refresh button to get the updated list:

Port	Select the port to which the entry refers.
VID	Displays the VLAN ID corresponding to the MAC address.
MAC Address	Displays the MAC addresses that the Switch learned from a specific port
