LABEL DESCRIPTION
VLAN Type Choose 802.1Q or Port Based. The SWITCHING > VLAN link and its sub-links only appears when
you choose 802.1Q VLAN type in this 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 1000000 seconds. This is how long all dynamically learned MAC
addresses remain in the MAC address table before they age out (and must be relearned).
ARP Aging Time
Aging Time Enter a time from 60 to 1000000 seconds. This is how long dynamically learned ARP entries
remain in the ARP table before they age out (and must be relearned). The setting here applies
to ARP entries which are newly added in the ARP table after you click Apply.
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 Declarations are withdrawn by issuing a Leave message.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 Timer 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.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
