VLAN Port Configuration
The VLAN Port Configuration screen, shown in Figure 6-31, 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.
• 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.
• 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.
Select Apply to make changes. Select OK to return to the previous panel.
Select Cancel to cancel any changes. Select Prev Port to view the previous
port. Select Next Port to view the next port. To display a specific port, set the
port number in the Page field and then press Apply.
VLAN Table Configuration
The VLAN Table Configuration screen, shown in Figure 6-32, is used to
create a new VLAN or modify the settings for an existing VLAN.
• VLAN - The ID for the VLAN currently displayed. The range is 1-2048.
