Dynamic Addresses The Dynamic Address Table contains the MAC addresses acquired by monitoring the source addresses of traffic entering the switch. When the destination address for inbound traffic is found in the database, the packets intended for that address are forwarded directly to the associated port. Otherwise, the traffic is flooded to all ports in the VLAN of the frame. To prevent the table from overflowing and to make room for new addresses, an address is deleted from the table if no traffic is received from a dynamic MAC address for a certain period. This period of time is called the aging interval. To configure dynamic addresses: 1 Click Switch > Address Tables > Dynamic MAC Address in the tree view to display the Dynamic Address page. Figure 11-2. Dynamic Address Table The current address table is displayed along with other parameters. 2 Enter Address Aging (10-630). The aging time is a value between the user- configured value and twice that value minus 1. For example, if you entered 300 seconds, the aging time is between 300 and 599 seconds.
