Gvrp Settings - D-Link DES-6500 - Switch User Manual

GVRP Settings

In the Configuration menu, open the VLANs
folder and click GVRP Settings.
The GVRP Settings dialog box, shown below,
allows users to determine whether the Switch will
share its VLAN configuration information with
other GARP VLAN
(GVRP) enabled switches. In addition, Ingress
Checking can be used to limit traffic by filtering
incoming packets whose PVID does not match
the PVID of the port. Results can be seen in the
table under the configuration settings, as seen
below.
The following fields can be set:

Registration Protocol
Description
Choose the Switch ID number of the line card in the chassis to be modified.
These two fields allow users to specify the range of ports that will be included in the Port-based
VLAN that you are creating using the GVRP Settings page.
The Group VLAN Registration Protocol (GVRP) enables the port to dynamically become a
member of a VLAN. GVRP is Disabled by default.
This field can be toggled using the space bar between Enabled and Disabled.
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 Enabled by default.
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.
Within the GVRP Settings above, the user may specify the default VLAN ID to be associated
with the port being configured for GVRP.
The read only field in the GVRP 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 a packet is received by the port, 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.
