VLAN Type 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

Bridge control
protocol
transparency 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 MAC address learning reduces outgoing traffic broadcasts. For MAC address
learning to occur on a port, the port must be active.
Aging Time 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).
300
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 Declarations are withdrawn by issuing a Leave message.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.
