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.
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.
