DESCRIPTION
Enter a number between 1 and 4094 as the port VLAN ID. If an incoming frame
received by the port is untagged, the device adds the port VLAN ID (PVID) to the
frame.
Select this to have the device discard incoming frames for VLANs that do not
include this port in its member set.
Clear this check box to disable ingress filtering on the port.
GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a
way for switches to register necessary VLAN members on ports across the network.
Select this check box to allow GVRP on this port.
Specify the type of frames allowed on a port. The available options vary depending
on device models.
Select All from the drop-down list box to accept all untagged or tagged frames on
this port. This is the default setting.
Select Tag Only to accept only tagged frames on this port. All untagged frames
will be dropped.
Enable VLAN Trunking on ports connected to other switches or routers (but not
ports directly connected to end users) to allow frames belonging to unknown VLAN
groups to pass through the device.
Click Apply to save your changes.
Click Reset to discard your changes and reset the fields to their last saved
settings.
