LABEL DESCRIPTION
IGMP Snooping Select Active to enable IGMP snooping have group multicast traffic only
forwarded to ports that are members of the VLAN, significantly reducing multicast
traffic passing through your AAM.
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 765 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 Declarations are withdrawn by issuing a Leave message.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.
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.
