D-Link DES-3250TG manual Port Bandwidth, Ingress Disabled Acceptable Frame Types

D-Link DES-3250TG Standalone Layer 2 Switch

Parameter	Description
From and To	Enter the desired ports in these two
	fields.
PVID	A Port VLAN Identifier is a classification
	mechanism that associates a port with a
	specific VLAN and is used to make
	forwarding decisions for untagged
	packets received by the port. For
	example, if port #2 is assigned a PVID of
	3, then all untagged packets received on
	port #2 will be assigned to VLAN 3. This
	number is generally the same as the
	VID# number assigned to the port in the
	Modify 802.1Q VLANs menu above.
GVRP <Disabled>	The Group VLAN Registration Protocol
	(GVRP) enables the port to dynamically
	become a member of a VLAN.

Ingress <Disabled>

Acceptable Frame Types

This field can be toggled using the space bar between Enabled and Disabled. Enabled enables the port to compare the VID tag of an incoming packet with the PVID number assigned to the port. If the two are different, the port filters (drops) the packet. Disabled disables Ingress filtering.

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 Admit_All, which means both tagged and untagged frames will be accepted. Admit_All is enabled by default.

To enable or disable GVRP, globally, on the switch:

Go to the Configuration menu and click Advanced Settings. Toggle the drop-down menu for GVRP Status between Enabled and Disabled. Click Apply to let your change take effect.

Port Bandwidth

The Bandwidth Settings window allows you to set and display the Ingress bandwidth and Egress bandwidth of specified ports on the switch.
