LABEL DESCRIPTION
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 screen.
See
Chapter 8 on page 91 for more information.
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).
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 Declarations are withdrawn by issuing a Leave message.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.
Leave Timer Leave Time sets the duration of the Leave Period timer for GVRP in milliseconds.
Each port has a single Leave Period timer. Leave Time must be two times larger
than Join Timer; the default is 600 milliseconds.
Leave All Timer Leave All Timer sets the duration of the Leave All Period timer for GVRP in
milliseconds. Each port has a single Leave All Period timer. Leave All Timer must be
larger than Leave Timer.
