10 VLAN Settings
VLAN menu allows configuring virtual LAN segments to segregate broadcast
domains. VLAN information is mapped directly at the Ethernet frame, and it is
standardized by IEEE 802.1Q. VLAN is the main way to segregate traffic from station
and process bus at Reason Switches. Sampled Values, GOOSE, PTP, MMS and other
messages can be segregated from each other using VLAN, increasing performance
on it usage in power system applications.
VLANs menu is located at Settings  VLANs.

Global VLAN Configuration:
Global VLAN Configuration menu contains basic configurations used by VLAN
function. These configurations are the allowed access VLANs and the Ethertype that
can be used for S-custom ports.
o
Allowed Access VLANs : indicates the VLAN identifiers allowed
when port Mode is Access. By default, only VLAN ID 1 is allowed in
ports configured as Access ports. If required, it can be added VLAN
identifiers. Allowed values are the VLAN range values (from 1 to
4,095). It is possible to insert specific VLAN identifiers separated by
comma (for instance, 1,2,10,40), a range of VLAN identifiers using
the “ - “ character (for instance, 10 -40), and a meshed specific and
range VLAN identifiers (for instance, 1,2,10-40);
o
Ethertype for Custom S-ports : indicates Ethertype allowed (in
addition to 802.1Q defined 0x8100 Ethertype) to ingress if port is
configured as S-Custom-Port. When a frame has the Ethertype
configured at this field, it will be classified to the VLAN ID
embedded at the frame or, if no VLAN ID is embedded, it will be
classified to the Port VLAN identifier. Values must be inserted in
hexadecimal format.

Port VLAN Configuration:
Port VLAN Configuration menu contains allowed per port configurations used by
VLAN function. This menu allows configuring all VLAN settings at a given port. Port
operation mode, allowed VLAN identifiers, VLAN filtering rules are examples of the
configuration that this menu allows to be done.
If one configuration is desired to be applied at all ports, then the row “*” should be
used, that is, configuration done in the “*” row will be replied to all ports. Possible
configurations are as follows.
o
Port : shows the port to be configured at this row;
