Table 12 Basic Setting > Switch Setup LABEL VLAN Type Bridge Control Protocol Transparency MAC Address Learning Aging Time DESCRIPTION Choose 802.1Q or Port Based. The VLAN Setup screen changes depending on whether you choose 802.1Q VLAN type or Port Based VLAN type in this screen. See Chapter 10 on page 129 for more information. Select Active to allow the Switch to handle bridging control protocols (STP for example). You also need to define how to treat a BPDU in the Port Setup screen. MAC address learning reduces outgoing traffic broadcasts. For MAC address learning to occur on a port, the port must be active. Enter a time from 10 to 3000 seconds. This is how long all dynamically learned MAC addresses remain in the MAC address table before they age out (and must be relearned). GARP Timer: Switches join VLANs by making a declaration. A declaration is made by issuing a Join message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations. GARP timers set declaration timeout values. See the chapter on VLAN setup for more background information. Join Timer Join Timer sets the duration of the Join Period timer for GVRP in milliseconds. Each port has a Join Period timer. The allowed Join Time range is between 100 and 65535 milliseconds; the default is 200 milliseconds. See the chapter on VLAN setup for more background information.
