LABEL DESCRIPTION
MAC Address
Learning
Aging Time
Enter a time from 10 to 10,000 seconds. This is how long all dynamically
learned MAC addresses remain in the MAC address table before they age out
(and must be relearned). Enter 0 to disable the aging out of MAC addresses.
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 Declarations are withdrawn by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. Click here for more information on
VLANs.
Join Timer (STU-C mode only) 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.
Leave Timer (STU-C mode only) 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 (STU-C mode only) 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.
Port Isolation
Active (STU-C mode only) Turn on port isolation to block communications between
subscriber ports. When you enable port isolation you do not need to configure
the VLAN to isolate subscribers.
