Select Modify to display the GARP Port Configuration screen.3.
Make a selection in Acceptable frame types to set how you
want a specific port to handle incoming packets.
All frames sets the port to accept packets with or without a
VLAN tag.
VLAN-tagged only sets the port to drop all packets without a
VLAN tag.
4.
Ingress filtering sets the port's filtering behavior—whether this
port should accept or discard tagged frames that are for
VLANs to which this port does not belong.
enabled - drop all packets destined for other VLANs
disabled - accept all packets regardless of whether or not this
port is a member of the same VLAN

Timers
The Switch issues GVRP PDUs to other 802.1Q devices to
update VLAN membership information dynamically. The
802.1Q devices use this information to add and delete dynamic
VLANs or add and delete ports.
Three timers set the interval that the Switch uses before
issuing updates to other devices. These timers are set to the
default values specified in the IEEE standard. All values are in
milliseconds.
Join time sets the frequency of messages issued when a new port has been added to the VLAN.
Leave time sets the frequency of messages issued when a single port no longer belongs to the VLAN.
Leaveall time sets the frequency of messages issued when all ports no longer belong to the VLAN and the
VLAN should be deleted.
Follow these rules if you must change the default settings:
1. The value for leave time must be at least three times greater than the join time value.
2. The value for leaveall time must be greater than the value for leave time.
3. The timer values on all connected devices must be identical for GVRP to operate successfully.
