VLAN Management
A VLAN is a group of ports that can be located anywhere
in the network, but communicate as though they belong
to the same physical segment.
VLANs help to simplify network management by allowing
you to move devices to a new VLAN without having
to change any physical connections. VLANs can be
easily organized to reflect departmental groups (such
as Marketing or R&D), usage groups (such as e-mail), or
multicast groups (used for multimedia applications such
as videoconferencing). You can create up to 128 VLANs on
the Switch.
VLAN Management > Create VLAN
The Create VLAN screen lets you create and configure
global parameters for VLANs.
VLAN Management > Create VLAN
Single VLAN
To create a single VLAN, enter the VLAN ID and VLAN
Name, up to 32 characters long, and click Add.
VLAN ID ID of configured VLAN (2-4093, no leading
zeroes).
VLAN Name Name of the VLAN. (1 to 32 characters)
VLAN Range
To create a range of VLANs, enter the range of their IDs in
the VLAN Range fields and then click Add Range.
VLAN Table
This section lists the current VLANs in tabular format. For
each VLAN, it displays the VLAN’s ID, name, and status. The
status values are Static (user-defined VLAN) or Default
(default VLAN). The total number of VLANs is also shown.
To remove a VLAN or a range of VLANs, select the VLANs in
the VLAN Table, then click Delete.
VLAN Management > Port Settings
The Port Settings screen allows you to configure the ports
in a VLAN.
VLAN Management > Port Settings
You can configure VLAN behavior for specific ports,
including the accepted frame type, VLAN identifier (PVID),
and ingress filtering.
Port The number of the port.
Acceptable Frame Type This specifies the type of frames
that the port will accept. If All (default) is selected, the
port will accept all frame types, including tagged or
untagged frames. If Tagged is selected, the port accepts
only tagged frames. When set to All, any untagged frames
that are received are assigned to the default VLAN.
PVID Use this field to select the VLAN ID that will be
assigned to untagged frames received on the port.
Valid IDs are 1 (default) to 4093. VLAN 4094 is reserved
for internal use. VLAN 4095 is defined per standard and
industry practice as the Discard VLAN. Frames tagged for
the Discard VLAN are dropped.
Ingress Filtering Enables or disables Ingress filtering
on the port. Ingress filtering discards packets that do not
include an ingress port. The default is Enabled.
LAG Displays the LAG, if any, to which the port belongs. A
port’s LAG settings override the VLAN port settings.
Click Save Changes to save your changes, or click Cancel
Changes to cancel.
VLAN Management > Port to VLAN
You use the Port to VLAN screen to add ports to a VLAN and
delete ports from a VLAN. When you add a port to a VLAN,
you also specify whether the port is tagged or untagged.
The Port to VLAN screen contains a Port Table with VLAN
parameters for each port. To add a port to or delete a
port from the VLAN, you select the port’s appropriate
configuration options from this table.
