Making VLAN Connections
The switch supports VLANs that can be used to organize any group of
network nodes into separate broadcast domains. VLANs confine
broadcast traffic to the originating group, and can eliminate broadcast
storms in large networks. This provides a more secure and cleaner network
environment.
VLANs can be based on untagged port groups, or traffic can be explicitly
tagged to identify the VLAN group to which it belongs. Untagged VLANs
can be used for small networks attached to a single switch. However,
tagged VLANs should be used for larger networks, and all the VLANs
assigned to the inter-switch links.

Note: When connecting to a switch that does not support IEEE 802.1Q
VLAN tags, use untagged ports.
