Making VLAN Connections

This switch supports VLANs which 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. Unttagged 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.

The switch also supports multiple spanning trees which allow VLAN groups to
maintain a more stable path between all VLAN members. This can reduce the
overall amount of protocol traffic crossing the network, and provide a shorter
reconfiguration time when any link in the spanning tree fails.

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

untagged ports.
