Layer 3 Management 24-Port 10/100 + 2-Port Gigabit Ethernet Switch
•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.

ic port does not belong to.

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 re-join before the port actually leaves the group.
