AKING

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.

This 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 if any link in the spanning tree fails.
