VLAN configuration
A Virtual LAN (VLAN) can be thought of as a broadcast domain that exists
within a switch or a defined set of switches. By grouping switch ports into
VLANs, traffic flooding is limited since devices can only communicate
directly with devices belonging to the VLAN. Creating a VLAN from a switch
is the logical equivalent of reconnecting a group of devices to another Layer
2 switch. However, the network devices retain their same physical
connection. The EIR505 series switches support port-based and 802.1Q
(tagged-based) VLAN. In the default configuration, the VLAN option is
disabled.
VLAN Configuration interface
Port-based VLAN
With port-based VLAN, the port is assigned to a VLAN. Therefore all
devices attached to a given port should be members of the same VLAN. As
with other VLAN configurations, the packets forwarded using this method do
not leak into other VLAN domains on the network. After the port has been
assigned to a VLAN, devices on the port cannot send to or receive from
devices in other VLANs without the intervention of another layer 3 device or
the ability to tag the data packet with a specific PVID.
