choose 802.1Q VLAN type or Po rt Ba se d 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 Jo in message using
GARP. Declarations are withdrawn by issuing a Le a ve message. A Le a ve 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 Jo in
Pe rio d timer. The allowed Jo in Tim e 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 Le a ve Pe rio d timer for GVRP in milliseconds. Each port has a
single Le a ve Pe rio d timer. Leave Time must be two times larger than Jo in Tim e r; the default is 600
milliseconds.
