D-Link DES-2108/E [44/199] The spanning tree algorithm sta in the switch allows you to create alternative paths with multiple switches or other types of bridges in your network these backup paths are idle until the switch determines that a problem has developed in the primary paths when a primary path is lost the switch providing the alternative path will automatically go into service with no operator intervention this automatic network reconfiguration provides maximum uptime to network users the concept of the spanning tree algorithm is a complicated and complex subject and must be fully researched and understood please read the following before making any changes

a VLAN (VLAN 2, for example) destined for a device on
another VLAN (VLAN 3) will be filtered.
Spanning Tree Algorithm
The Spanning Tree Algorithm (STA) in the Switch allows you to
create alternative paths (with multiple switches or other types of
bridges) in your network. These backup paths are idle until the
Switch determines that a problem has developed in the primary
paths. When a primary path is lost, the switch providing the
alternative path will automatically go into service with no operator
intervention. This automatic network reconfiguration provides
maximum uptime to network users. The concept of the Spanning
Tree Algorithm is a complicated and complex subject and must be
fully researched and understood. Please read the following before
making any changes.
♦ Network loop detection and prevention With STA,
there will be only one path between any two LANs. If there is
more than one path, forwarded packets will loop indefinitely.
STA detects any looped path and selects the path with the
lowest path cost as the active path, while blocking the other
path and using it as the backup path.
♦ Automatic topology re-configuration When the path for
which there is a backup path fails, the backup path will be
automatically activated, and STA will automatically re-
configure the network topology.
STA Operation Levels
STA operates on two levels: the bridge level and the port level. On
the bridge level, STA calculates the Bridge Identifier for each
