3- 9 Filtering Data Base Filtering Data Base Configuration gathers many functions, including MAC Table Information, Static MAC Learning, which cannot be categorized to some function type. MAC table Switching of frames is based upon the DMAC address contained in the frame. The switch builds up a table that maps MAC addresses to switch ports for knowing which ports the frames should go to (based upon the DMAC address in the frame). This table contains both static and dynamic entries. The static entries are configured by the network administrator if the administrator wants to do a fixed mapping between the DMAC address and switch ports. The frames also contain a MAC address (SMAC address ), which shows the MAC address of the equipment sending the frame. The SMAC address is used by the switch to automatically update the MAC table with these dynamic MAC addresses. Dynamic entries are removed from the MAC table if no frame with the corresponding SMAC address has been seen after a configurable age time 3- 9.1 Configuration The MAC Address Table is configured on this page. Set timeouts for entries in the dynamic MAC Table and configure the static MAC table here. Web Interface To configure MAC Address Table in the web interface: Aging Configuration 1. Click configuration . 2. Specify the Disable Automatic Aging and Aging Time. 3. Click Apply. MAC Table Learning 1. Click configuration . 2. Specify the Port Members(Auto,Disable,Secure). 3. Click Apply. Static MAC Table Configuration 1. Click configuration and Add new Static entry . 2. Specify the VLAN IP and Mac address ,Port Members. 3. Click Apply. Figure 3- 9.1: The MAC Address Table Configuration Parameter description:  Aging Configuration : By default, dynamic entries are removed from the MAC table after 300 seconds. This removal is also called aging. Configure aging time by entering a value here in seconds; for example, Age time seconds. 119
