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 Declarations are withdrawn by issuing a Leave message.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.
