7.8 Spanning Tree
Spanning tree is a protocol to prevent network loop in network topology. If
network loop happens, it will cause the network unstable because more and
more traffic will loop in the network. If network loop happens, spanning tree
protocol will block one connection in the loop automatically. But it will also
cause a period of delay (30 seconds for STP and shorter time for RSTP) if any
network connection is changed because of the network topology detection
operation of the protocol.
This switch supports MSTP/RSTP/STP functions. Configuring them for
spanning tree operation is done here.
