■ The Spanning Tree Protocol (STP) is a network protocol that
ensures a loop-free topology for bridged local area networks
(LANs). STP allows a network design to include spare
(redundant) links to provide automatic backup paths via STP
without the need for manual intervention. When STP is
enabled, the protocol monitors the participating ports/
VLANs. Should there be a change in topology (a port goes
active or a port goes down) STP blocks traffic on
participating ports until the network topology is determined.
Scale Computing recommends disabling STP on the LAN
and Backplane ports. If STP is required then Rapid STP is
recommended.
■ Flow control is useful for managing the data rates between
two links. It helps prevent a fast sending connection from
overwhelming a slower receiving connection and causing
