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 specied 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.
