VLAN Port Configuration
The VLAN Port Configuration screen allows you to configure GARP, the default VLAN identifier, default port priority, VLAN tagging on the attached link, GVRP and GMRP status, and filtering of incoming frames for VLAN groups a specific port does not belong to.
GARP
Group Address Registration Protocol is used by GVRP and GMRP to regis- ter or deregister client attributes for client services within a bridged LAN.
•Join Time - The interval (centiseconds) between transmitting requests/queries to participate in a group.
•Leave Time - The interval (centiseconds) a port waits before leaving a group. This time should be set to more than twice the Join Time. This ensures that after a Leave or Leave All message has been issued, the applicants can

•Leave All Time - The interval (centiseconds) between sending out a Leave All query message for group participants and the port leaving the group. This interval should be considerably larger than the Leave Time to minimize the amount of traffic generated by nodes rejoining the group.
VLAN and Priority
These fields set the default values for VLANs, port priority, GVRP, and GMRP.
•Port VID - The VLAN ID assigned to untagged frames received on this port.
•Port Default Priority - Sets the default ingress priority to any value beneath the priority threshold to specify the low priority queue, or to any value equal to or above this threshold to specify the high priority queue.
•VLAN Tagging - Indicates whether or not VLAN tags will be included on frames passing through this port.
•GVRP - Enables or disables GVRP for this port. When disabled, any GVRP packets received on this port will be discarded and no GVRP reg- istrations will be propagated from other ports. Note: GMVP must be enabled for the Switch before this setting can take effect.
•GMRP - Enables or disables GMRP for this port. When enabled, this port will allow endstations to register with multicast groups. Note: GMRP must be enabled for the Switch before this setting can take effect.
•Ingress Filtering - If enabled, incoming frames for VLANs that do not include this ingress port in their member set will be discarded at the ingress port.
