2-5Making 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.

Figure 2-4 Making VLAN Connections

Note: When connecting to a switch that does not support IEEE 802.1Q

VLAN tags, use untagged ports.
