Switch Configuration and Spanning Tree

The Switch Configuration menu offers one option, Spanning Tree; see Figure 13.

Ethernet bridges or switches use the Spanning Tree Protocol (STP), an algorithm that creates a logical
topology that connects all network segments and ensures only one path between any two stations.
When STP is enabled, the 9135 monitors the incoming data packets and periodically sends Bridge
Protocol Data Units (BPDU). STP monitors the incoming BPDUs to detect any loops. If the same
BPDU arrives on two ports, STP blocks one port to remove the loop. Because this tree-like structure
spans all nodes in the network, it is called Spanning Tree. Figure 14 shows a typical STP application.
