54 CHAPTER 6 • RAPID SPANNING TREE
Example
In the following network topology (six) redundant paths have been created to ensure
access to all network devices in the event of a data path failure (see Figure 6.1). These
redundant paths are impermissible loops. The RSTP protocol automatically converts
this topology into a tree by disconnecting selected ports. In this context, one of the
switches is assigned the role of the root of the tree. From this root, all other switches
can be accessed via a single data path.

RSTP Startup
Startup consists of two parts that must be executed in the specified order:
1 Enable RSTP on all switches that are to be operated as active RSTP components in the
network.
2 Connect the switches to form a meshed topology.
Caution
Only create the meshed topology after activating RSTP
RSTP can be activated via Web-based management or via a serial interface. Telnet and
SNMP interface can also be used to activate RSTP.
