Sample POST Results
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 SEEPROM, temperature sensor, and
Ethernet-end-of-band channel (eobc), when used.

The following example illustrates the output of a CPU subsystem test on all supervisor engines except
the WS-X4013+TS:

For traffic tests, 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.

POST also performs tests on the packet and system memory of the switch. These are numbered
dynamically in ascending order starting with 1 and represent different memories.

POST also tests the Netflow services card (Supervisor Engine IV and Supervisor Engine V) and the
Netflow services feature (Supervisor Engine V -10GE). Failures from these tests are treated as marginal,
as they do not impact functionality of the switch (except for the unavailability of the Netflow features):
