(Rapid) Spanning Tree

5.1

(R)STP startup

Startup consists of two parts that must be executed in the specified order:

Enable (R)STP on all switches that are to be operated as active (R)STP components in

the network.

Connect the switches to form a meshed topology.

5.1.1

Enabling (R)STP on all switches involved

(R)STP can be activated via web-based management, via the SNMP interface or via the

serial interface.

Only create the meshed topology after activating (R)STP.

While learning the network topology, the switch temporarily does not participate in

network communication.
