xStack DGS/DXS-3300 Series Layer 3 Stackable Gigabit Ethernet Switch User Manual Parameter Unit Description Choose the Switch ID number of the Switch in the switch stack to be modified. From/To These two fields allow the user to specify the range of ports that will be included in the Port-based VLAN that you are created using the GVRP Settings page. GVRP The Group 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 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 Admit_All, which means both tagged and untagged frames will be accepted. Admit_All is enabled by default. PVID 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. Click Apply to implement changes made. 83

xStack DGS/DXS-3300 Series Layer 3 Stackable Gigabit Ethernet Switch User Manual
83
Parameter
Description
Unit
Choose the Switch ID number of the Switch in the switch stack to be modified.
From/To
These two fields allow the user to specify the range of ports that will be included in
the Port-based VLAN that you are created using the
GVRP Settings
page.
GVRP
The Group 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 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
Admit_All
, which means both tagged and untagged frames will be
accepted.
Admit_All
is enabled by default.
PVID
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.
