mode, entire VLANs can be deleted. VLANs to be edited can be selected by either the
VID:[ ]
field or the
VLAN
Name:[ ]
fields. Enter either the VID or the VLAN Name for the 802.1Q VLAN you want to edit and press
Enter
.
Note
:
To delete an entire VLAN, toggle the
Action:<
Add/Modify
>
field to
Delete,
enter either the
VID or the VLAN Name in the appropriate field and press
Enter
.
Highlight
Apply
and press
Enter
.
The selected VLAN will be deleted. To enter the change into Non-volatile RAM, select
Save Changes
from the
Main Menu
.
The 802.1Q VLANs are edited by specifying which ports will be Egress Members, Forbidden non-members or non-
members.
The ports are further set to be either a Tagged or an Untagged port.
To edit the 802.1Q VLAN membership of a port
:
Highlight the first field of
Membership (
E
/
F
/-): [ ][ ][ ]
. Each port’s 802.1Q VLAN membership can be set individually
by highlighting the port’s entry using the arrow keys, and then toggling between
E
,
F
, or – using the space bar.
•
E
- (Egress Member) specifies the port as being a static member of the VLAN. Egress Member Ports are
ports that will be transmitting traffic for the VLAN. These ports can be either tagged or untagged.
•
F
- (Forbidden Non-Member) specifies the port as not being a member of the VLAN and that the port is
forbidden from becoming a member of the VLAN dynamically.
•
(Non-Member) specifies the port as not being a member of the VLAN, but the port can become a member of
the VLAN dynamically.
To edit a port’s Tagged or Untagged status:
Highlight the first field of
Tagging (
U
/
T
):[ ][ ][ ]
field. Each port’s state can be set by highlighting the port’s entry using
the arrow keys and then toggling between
U
or
T
using the space bar.
•
U
- specifies the port as an Untagged member of the VLAN. When an untagged packet is transmitted by the
port, the packet header remains unchanged. When a tagged packet exits the port, the tag is stripped and the
packet is changed to an untagged packet.
•
T
- specifies the port as a Tagged member of the VLAN. When an untagged packet is transmitted by the port,
the packet header is changed to include the 32-bit tag associated with the PVID (Port VLAN Identifier – see
below). When a tagged packet exits the port, the packet header is unchanged.
If the port is attached to a device that is not IEEE 802.1Q VLAN compliant (VLAN-tag unaware), then the port should be
set to
U
– Untagged.
If the port is attached to a device that is IEEE 802.1Q VLAN compliant, (VLAN-tag aware), then the port should be set to
T
– Tagged.
Each port can be configured to have a PVID or to use an Ingress Filter.
To configure a port’s 802.1Q VLAN settings:
Highlight the
Configure Port#[ ]
field and enter the port number of the port you want to configure. Use the arrow keys
to highlight the
PVID#[ ]
field and enter the PVID for the port.
•
PVID
– A Port VLAN Identifier is a classification mechanism that associates a port with a specific VLAN
and is used to make forwarding decisions for untagged packets received by the port. For example, if port #2 is
assigned a PVID of 3, then all untagged packets received on port #2 will be assigned to VLAN 3. This number
is generally the same as the VID# number assigned to the port in the
Edit Existing 802.1Q VLANs
menu
above.
Use the arrow keys to highlight the remaining fields and the space bar to toggle between
On
and
Off
.
