D-Link DGS-3700 user manual Gvrp Global Settings, Pvid

	DGS-3700-12/DGS-3700-12G Series Layer 2 Gigabit Ethernet Switch User Manual
The following fields can be set:
Parameter		Description
From Port / To Port		These two fields allow you to specify the range of ports that will be included in the Port-based
		VLAN that you are creating using the 802.1Q Port Settings window.
GVRP		The Group VLAN Registration Protocol (GVRP) enables the port to dynamically become a
		member of a VLAN. GVRP is Disabled by default.
PVID		The read-only field in the 802.1Q Port Table shows the current PVID assignment for each
		port, which may be manually assigned to a VLAN when created in the 802.1Q Port Settings
		table. 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.
Ingress Check		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. Ingress Checking is Disabled by default.
Acceptable Frame		This field denotes the type of frame that will be accepted by the port. The user may choose
Type		between Tagged Only, which means only VLAN tagged frames will be accepted, and
		Admit_All, which mean both tagged and untagged frames will be accepted. Admit_All is
		enabled by default.

GVRP Global Settings

The GVRP allows interoperability with other switches, so the values of the GVRP timers can be configured. This table is used to set the GVRP Global Settings.

To view this window, click L2 Features > GVRP Global Settings as shown below:

Figure 3 - 20 GVRP Timer Settings window

The following fields can be set:

Parameter Description

Join Time	The time in milliseconds that specifies the amount of time between the Switch receiving the
(100-100000)	information about becoming a member of the group and actually joining the group. The default
	is 200.
Leave Time	The time in milliseconds that specifies the maximum amount of time between the Switch
(100-100000)	receiving a leave group message from a host, and the Switch issuing a group membership
	query. The default is 600. The Leave Time must be greater than 2 join times.
