27.1 Overview

This chapter shows you how to configure the Switch to guard against loops on the
edge of your network.
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.
