GVRP Settings

The GVRP Settings window allows the user to
determine whether the Switch will share its
VLAN configuration information with other
GARP VLAN Registration Protocol (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.
To view this window, click L2 Features >
VLAN > GVRP Settings, as shown on the right:
The following fields can be configured:
Parameter Description
Unit Select the switch in the switch stack to be modified.
From / To
These two fields allow the range of ports that will be included in the Port-based VLAN created
using the 802.1Q Port Settings window, to be specified.
GVRP The GARP VLAN Registration Protocol (GVRP) enables the port to dynamically become a member
of a VLAN. GVRP is Disabled by default.
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 Enabled by default.
Acceptable This field denotes the type of frame that will be accepted by the port. The user may choose
Frame 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.
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
