Unchecked - Maintains the current ARP entries. Interface - Indicates the VLAN for which ARP parameters are defined. IP Address - Indicates the station IP address which is associated with the MAC address. MAC Address - Displays the station MAC address, which is associated in the ARP table with the IP address. Status - Displays the ARP table entry type. Possible field values are: Dynamic - Indicates the ARP entry is learned dynamically. Static - Indicates the ARP entry is a static entry. 2 Select the Interface to be removed. 3 Click Remove. The ARP interface is removed, and the device is updated. Configuring Address Tables MAC addresses are stored in either the Static Address or the Dynamic Address databases. A packet addressed to a destination stored in one of the databases is forwarded immediately to the port. The Dynamic Address Table can be sorted by interface, VLAN, and MAC Address. MAC addresses are dynamically learned as packets from sources arrive at the device. Addresses are associated with ports by learning the ports from the frames source address. Frames addressed to a destination MAC address that is not associated with any port, are flooded to all ports of the relevant VLAN. Static addresses are manually configured. In order to prevent the bridging table from overflowing, dynamic MAC addresses, from which no traffic is seen for a certain period, are erased.
