3.1.12 VLAN
Configuration
This page allows for controlling
VLAN
configuration on the switch. The page is divided into a global section and
a per-port configuration section.
Global VLAN Configuration
Allowed Access VLANs
This field shows the allowed Access VLANs, i.e. it only affects ports configured as Access ports. Ports in other
modes are members of the VLANs specified in the Allowed VLANs field. By default, only VLAN 1 is enabled.
More VLANs may be created by using a list syntax where the individual elements are separated by commas.
Ranges are specified with a dash separating the lower and upper bound.
The following example will create VLANs 1, 10, 11, 12, 13, 200, and 300:
1,10-13,200,300
. Spaces are allowed in
between the delimiters.
Ethertype for Custom S-ports
This field specifies the ethertype/TPID (specified in hexadecimal) used for Custom S-ports. The setting is in force
for all ports whose Port Type is set to S-Custom-Port.
Port VLAN Configuration
Port
This is the logical port number of this row.
Mode
The port mode (default is Access) determines the fundamental behavior of the port in question. A port can be in
one of three modes as described below. Whenever a particular mode is selected, the remaining fields in that
row will be either grayed out or made changeable depending on the mode in question. Grayed out fields show
the value that the port will get when the mode is applied.
Access:
Access ports are normally used to connect to end stations. Dynamic features like Voice VLAN may add the port
to more VLANs behind the scenes. Access ports have the following characteristics:
•
Member of exactly one VLAN, the Port VLAN (a.k.a. Access VLAN), which by default is 1
