Media-related issues

This section provides procedures that help pinpoint any media-related issues, such as bad cables
and SFPs, in the fabric. The tests listed in
tests that can be used to provide an overview of the hardware components and help identify
media-related issues.

Structural tests perform basic testing of the switch circuit. If a structural test fails, replace the
main board or port blade.
Functional tests verify the intended operational behavior of the switch by running frames
through ports or bypass circuitry.

Media-related issues
Checks
Used to isolate problems to a single
replaceable element and isolate
problems to near-end terminal
equipment, far-end terminal
equipment, or transmission line.
Diagnostics can be executed every day
or on demand.
Tests switch-to-switch ISL cabling and
trunk group operations.
