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. 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.

The switch also supports multiple spanning trees which allow VLANs 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.

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

untagged ports.
