Identifying Media-Related Issues

Use the following section to narrow down media-related issues in the fabric.

Component Tests Overview

Hardware diagnostics available on switches can be classified into two different
types of tests:

Structural tests - do basic tests of the switch circuit. When structural tests fail,
replace the main board.
Functional tests - verify the intended operational behavior of the switch by
running frames through ports or bypass circuitry.

The crossport is set to loopback using
an external cable by default. However,
this command can be used to check
internal components by setting the
operand to 5.
