DGS-3024 Gigabit Ethernet Switch Manual 802.1Q Port Settings In the Configuration menu, open the VLANs folder and click 802.1Q Port Settings. This GVRP Settings window (shown below), allows you 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. The following fields can be set: Parameter Description Figure 7- 38. GVRP Settings window From/To These two fields allow you to specify the range of ports that will be included in the VLAN that you are creating using the GVRP Settings window. Ingress Check Frame Type PVID 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. 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. This 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 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. GVRP The Group VLAN Registration Protocol (GVRP) enables the port to dynamically become a member of a VLAN. GVRP is Disabled by default.

DGS-3024 Gigabit Ethernet Switch Manual

802.1Q Port Settings

In the

Configuration

menu, open the

VLANs

folder

and click

802.1Q

Port Settings

This

GVRP Settings

window (shown below), allows

you 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.

Figure 7- 38.

GVRP Settings window

The following fields can be set:

Parameter

Description

From/To

These two fields allow you to specify the range of ports that will be included in the VLAN that you

are creating using the

GVRP Settings

window.

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.

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

This 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 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.

GVRP

The Group VLAN Registration Protocol (GVRP) enables the port to dynamically become a

member of a VLAN. GVRP is

Disabled

by default.
