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

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 Declarations are withdrawn by issuing a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.
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.
