CHAPTER 22
Configuration: Loop Guard
22.1 Overview
This section provides information for Loop Guard in Configuration.
This chapter shows you how to configure the Switch to guard against loops on the edge of your
network.
22.2 Loop Guard
Loop guard allows you to configure the Switch to shut down a port if it detects that packets sent out
on that port loop back to the Switch. While you can use Spanning Tree Protocol (STP) to prevent
loops in the core of your network. STP cannot prevent loops that occur on the edge of your
network.
