2.10 Spanning Tree
EH7510 provides the IEEE Standard Spanning tree functionality. The Spanning Tree
Protocol (STP) provides function to prevent switching loops and ensuring broadcast
radiation. A switching loop occurs in network when there are multiple connections between
two network switches or two ports. The loop creates broadcast radiation, the accumulation
of broadcast and multicast traffic on a computer network. As broadcasts and multicasts are
forwarded by bridges/switches to every port, the bridges/switches will repeatedly
rebroadcast the broadcast messages, and this can floods the network. STP creates a
spanning tree and disables those links of the network that are part of the spanning tree,
which leaves only a single active path between two nodes. This function avoids flooding and
increases network efficiency.
EH7510 also supports RSTP (Rapid Spanning Tree Protocol). It is an evolution of the STP.
It has a slightly changed topology, which helps to provide a much faster spanning tree
convergence.
