STP Configuration

Spanning Tree Protocol (stp) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. It also allows a network design to include backup links to provide fault tolerance if an actilink fails.

Note 1: * = required parameter Note 2: **ne - Substitute olt for ne on the OLT2/OIU2 command lines

Create spanning-tree-protocol

1. From the ESUx> command line, input **ne spanning-tree-protocol create multiple-Spanning-Tree mstid=1234, and press Enter. Output similar to the following is displayed:

   ESUx> **ne spanning-tree-protocol create multiple-Spanning-Tree mstid=1234 <enter> success. ESUx> _

Show summary of spanning-tree-protocol configuration.

1. From the ESUx> command line, input **ne  stp show common-Spanning-Tree summary, and press Enter. Output similar to the following is displayed:
