Function Brief
STP is developed based on IEEE 802.1D, and is a protocol used to
eliminate physical loops at the data link layer in the LAN. STP-enabled
devices exchange information to detect loops on the network, and
selectively block some ports to change a loop topology into a loop-free tree
topology. This prevents continuous growing and infinite loop of packets on
the loop network, and prevents occurrence of problems such as degraded
packet processing capability of devices caused by repeated receiving of the
