The POST results are indicated with a period (.) or a Pass for Pass, an F for a Fail and a U for Untested.
POST Result Example
For all the supervisor engines, POST performs CPU, traffic, system, system memory, and feature tests.
For CPU tests, POST verifies appropriate activity of the supervisor engine SEEPROM, temperature
sensor, and Ethernet end-of-band channel (EOBC), when used.
The following example illustrates the output of a CPU subsystem test:

Cpu Subsystem Tests ...
seeprom: . temperature_sensor: . eobc: .
[..]
For traffic tests, the POST sends packets from the CPU to the switch. These packets loop several times
within the switch core and validate the switching, the Layer 2 and the Layer 3 functionality. To isolate
the hardware failures accurately, the loop back is done both inside and outside the switch ports.
The following example shows the output for a Supervisor Engine 6-E and Supervisor Engine 6L-E:
Switch# show diagnostic result module 3 detail
