Introduction
VLAN
A Virtual LAN is a software-defined broadcast domain. The switch’s VLAN
feature allows the network to be segmented by software management,
improving network performance. Workstations, servers, and other network
equipment connected to the switch can be grouped according to similar data
and security requirements.
By default the switch is configured to include all ports as untagged members
of a single default VLAN, with no VLAN tagging required on incoming
frames, or added to outgoing frames.
One port on the switch can be configured as an uplink to another 802.1Q
compatible switch. By using VLAN tagging, this one port can carry traffic
from all VLANs on the switch.
VLANs can consist of simple logical groupings of untagged ports, in which
the ports receive and transmit untagged packets. Alternatively, VLANs can
include tagged ports, which add VLAN tags to packets they transmit.
