VLAN
A VLAN is a group of ports that form a logical Ethernet
segment on an Ethernet switch. VLANs let you segment
your network through the switch’s management software
so that you can group nodes with related functions into
their own separate, logical LAN segments.

group, the data is discarded unless the port is a member of
the VLAN group.
Enabled: Enable802.1QVLANs.Thisfeatureisenabledby
default.
VID: Specify the VLAN Identier for the new VLAN. The
range of the VLAN ID is 1-4094.
Name: Specify a name for the VLAN.
Tagged Ports: Frames transmitted from this port are
tagged with the VLAN ID.
Untagged Ports: Frames transmitted from this port are
untagged.
Important: Port-based VLAN and 802.1Q VLAN
are mutually exclusive. If you enable port-based VLAN,
then802.1QVLANisdisabled.
Note: All ports with a VID of 1 are assigned to the
default VLAN.
