Setting the Port Spanning Tree Protocol

The Spanning Tree Protocol (STP) and the Rapid Spanning Tree Protocol

(RSTP) guard against the formation of loops in an Ethernet network

topology. A topology has a loop when two or more nodes can transmit

packets to each other over more than one data path. Packets can become

caught in repeating cycles, referred to as broadcast storms, that

needlessly consume network bandwidth and that can significantly reduce

network performance.

This chapter provides a brief description of the spanning tree protocols and

explains how to set spanning tree on a port. See the following sections:

 “Overview” on page 90

 “Displaying Port Spanning Tree Protocol Settings” on page 91

 “Modifying Port Spanning Tree Protocol Settings” on page 93

Note

For information about how to set a spanning tree protocol for the

switch, see Chapter 12, “Setting Switch Spanning Tree Protocols” on

page 135.

For more information about the spanning tree protocols, see the following

chapters in the AlliedWare Plus Management Software Command Line
