The fields that can be configured are described below:

Parameter Description

From Port / To Port

Select the starting and ending ports to use.

PVID (1-4094)

This field is used to manually assign a PVID to a VLAN. The Switch's default is to

assign all ports to the default VLAN with a VID of 1.The PVID is used by the port to

tag outgoing, untagged packets, and to make filtering decisions about incoming

packets. If the port is specified to accept only tagged frames - as tagging, and an

untagged packet is forwarded to the port for transmission, the port will add an

802.1Q tag using the PVID to write the VID in the tag. When the packet arrives at

its destination, the receiving device will use the PVID to make VLAN forwarding

decisions. If the port receives a packet, and Ingress filtering is Enabled, the port will

compare the VID of the incoming packet to its PVID. If the two are unequal, the port

will drop the packet. If the two are equal, the port will receive the packet.

GVRP

The GARP VLAN Registration Protocol (GVRP) enables the port to dynamically

become a member of a VLAN. GVRP is Disabled by default.

Ingress Checking

This drop-down menu allows the user to enable the port to compare the VID tag of

an incoming packet with the port VLAN membership. If enable ingress checking

and the reception port is not the member port of the frame’s VLAN, the frame shall

be discarded.

Acceptable Frame Type

This field denotes the type of frame that will be accepted by the port. The user may

choose between Tagged Only, which means only VLAN tagged frames will be

accepted, and All, which mean both tagged and untagged frames will be accepted.

All is enabled by default.

Click the Apply button to accept the changes made.

MAC-based VLAN Settings

Users can create new MAC-based VLAN entries, search and delete existing entries. When a static MAC-based

VLAN entry is created for a user, the traffic from this user will be able to be serviced under the specified VLAN.
