Spanning Tree; Spanning Tree Switch Configuration - HPE OfficeConnect 1920S8G series Management And Configuration Manual

Spanning Tree

Spanning Tree Protocol (STP) is a Layer 2 protocol that provides a tree topology for switches on a
bridged LAN. STP allows a network to have redundant paths without the risk of network loops. STP
uses the spanning-tree algorithm to provide a single path between end stations on a network. When
STP is enabled, bridges on a network exchange bridge protocol data units (BPDUs) to communicate
changes in the network topology and to provide information that helps determine the optimal paths
between network segments.
HPE OfficeConnect 1920S series switches support STP versions IEEE 802.1D (STP), and 802.1w
(Rapid STP, or RSTP). RSTP reduces the convergence time for network topology changes to about 3
to 5 seconds from the 30 seconds or more for the IEEE 802.1D STP standard. RSTP is intended as a
complete replacement for STP, but can still interoperate with switches running the STP protocol by
automatically reconfiguring ports to STP-compliant mode if they detect STP protocol messages from
attached devices.
