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 Table 6 are a combination of structural and functional

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.

The following procedures are for checking switch-specific components.

TABLE 6 Component test descriptions

Test name Operands Checks

portTest [-ports itemlist] [-iteration count]

[-userdelay time] [-timeout time]

[-pattern pattern] [-patsize size]

[-seed seed] [-listtype porttype]

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.

spinFab [-nmegs count] [-ports itemlist] [-setfail mode] Tests switch-to-switch ISL cabling and

trunk group operations.
