short command, which typically takes 10 to 15 minutes. Alternatively, you can run subsets of the
offline commands that check various parts of the hardware. The table below shows the complete list of
supported offline commands.
Offline diagnostic commandsTABLE 106
Offline diagnostic command Purpose
diag burninerrclear Clears the errors that are stored in the nonvolatile storage during the burn-
in process.
diag clearerror Clears the diagnostics failure status.
diag portledtest Runs various action modes on the port LEDs and validates the
functionality.
diag portloopbacktest Sends frames between various ASICs on the switch and validates the
ASIC functionality.
diag setcycle Configures all the parameters required for the system verification test.
diag systemverification Runs a combination of various hardware diagnostic tests.
diag turboramtest Performs a turbo static RAM (SRAM) test of the ASIC chips.
The table below lists the show commands that provide output from offline diagnostics.
Offline diagnostic show commandsTABLE 107
Show offline diagnostic command Purpose
show diag burninerrshow Displays the errors that are stored in the nonvolatile storage during burn-in.
show diag burninstatus Displays the diagnostics burn-in status.
show diag setcycle Displays the current values used in system verification.
show diag status Displays the currently running diagnostics tests.
For details of the commands listed in these tables, refer to the Network OS Command Reference.
Viewing routing information
The show fabric route pathinfo command displays routing and statistical information from a source
port index on the local switch to a destination port index on another switch in the same VCS Fabric
cluster, a different VCS Fabric cluster, a connected Fabric OS backbone fabric, or Fabric OS edge
fabric. This routing information describes the full path that a data stream travels between these ports,
including all intermediate switches.
The routing and statistics information are provided by every switch along the path, based on the
current routing table information and statistics calculated continuously in real time. Each switch
represents one hop.
