Spanning Tree Protocol; Spa Nning T Re E Pro To C O L; Spanning Tree Protocol Overview; What You Can Do - ZyXEL Communications GS1920v2 Series User Manual

13.1 Spa nning T re e Pro to c o l O ve rvie w
The Switch supports Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP) and Multiple
Spanning Tree Protocol (MSTP) as defined in the following standards.
• IEEE 802.1D Spanning Tree Protocol
• IEEE 802.1w Rapid Spanning Tree Protocol
• IEEE 802.1s Multiple Spanning Tree Protocol
The Switch also allows you to set up multiple STP configurations (or trees). Ports can then be assigned to
the trees.

(Ra pid) Spa nning T re e Pro to c o l
(R)STP detects and breaks network loops and provides backup links between switches, bridges or
routers. It allows a switch to interact with other (R)STP -compliant switches in your network to ensure that
only one path exists between any two stations on the network.
The Switch uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allows faster convergence of the
spanning tree than STP (while also being backwards compatible with STP-only aware bridges). In RSTP,
topology change information is directly propagated throughout the network from the device that
