VLAN
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, and
allows the network traffic to be isolated. Only members of the same VLAN will receive traffic
from the other members. Basically, to create a VLAN from a switch is the equivalent of
separating a group of network devices. However, all the network devices are still plugged into
the same switch physically.
This managed switch supports port-based and 802.1Q (tagged-based) VLAN. The default
configuration of VLAN operation mode is “
802.1Q
”.
5.1.8.1
VLAN Setting
Tagged-based VLAN is an IEEE 802.1Q specification standard. It allows the creation of VLAN’s
across devices from different switch vendors. IEEE 802.1Q VLAN uses a technique which
inserts a “tag” into the Ethernet frame. Tags contain a VLAN Identifier (VID) that indicates the
VLAN number.
