Default VLANs
The Managed Switch initially configures one VLAN, VID = 1, called
"default."
The factory default setting assigns all ports on the
Switch to the
"default"
. As new VLAN are configured in Port-based mode, their respective member ports are removed from the
"default."
VLAN and Link aggregation Groups
In order to use VLAN segmentation in conjunction with port link aggregation groups, you can first set the port link aggregation
group(s), and then you may configure VLAN settings. If you wish to change the port link aggregation grouping with VLAN
already in place, you will not need to reconfigure the VLAN settings after changing the port link aggregation group settings.
VLAN settings will automatically change in conjunction with the change of the port link aggregation group settings.
4.4.2 Static VLAN Configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so
only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is logically
equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plug
into the same switch physically.
The Managed Switch supports
Port-based
and
802.1Q (Tagged-based)
VLAN in web management page. In the default
configuration, VLAN support is “
802.1Q
”.

No matter what basis is used to uniquely identify end nodes and assign these nodes
VLAN membership, packets cannot cross VLAN without a network device performing a
routing function between the VLAN.

The Managed Switch supports
Port-based VLAN
and
IEEE 802.1Q VLAN
. The port
untagging function can be used to remove the 802.1 tag from packet headers to
maintain compatibility with devices that are tag-unaware.
