1.1 STP Overview
I. Functions of STP
Spanning tree protocol (STP) is a protocol conforming to IEEE 802.1d. It aims to
eliminate loops on data link layer in a local area network (LAN). Devices running this
protocol detect loops in the network by exchanging packets with one another and
eliminate the loops detected by blocking specific ports until the network is pruned into
one with tree topology. As a network with tree topology is loop-free, it prevents packets
in it from being duplicated and forwarded endlessly and prevents device performance
degradation.
Currently, in addition to the protocol conforming to IEEE 802.1d, STP also refers to the
protocols based on IEEE 802.1d, such as RSTP, and MSTP.
