Fabric OS Commands
This command may also be looped by specifying the nSeconds operand. For
example, diagshow 4 executes diagshow every 4 seconds continuously
until stopped by a keyboard interrupt. This may be used to isolate a bad SFP. A
port with changing "LLI_errs" value prefixed by "**" indicates port is detecting
more errors.
Operands
This command has the following operands:
nSeconds
(V3.1.x only)
--slot slotnumber
(V4.1.x only)
-uports itemlist
(V4.1.x only)
-bports itemlist
(V4.1.x only)
-use_bports value
(V4.1.x only)
206
The state of the Central Memory based on the results of diagnostic executions
since the last reboot. OK is displayed if previous centralmemorytest
executions passed. FAULTY is displayed if the switch failed
centralmemorytest.
The total diagnostic frames transmitted and received since last reboot.
The sums represent the cumulative number of frames transmitted and received
by the diagnostic functional tests (portloopbacktest,
crossporttest, or spinsilk for the transmitted count only) for all
ports since the last reboot.
For example, if the switch is rebooted with POST disabled, diagshow will
show the total as 0. The values are not necessarily equal. They are not equal
when an error occurs in one of the ports during one of the tests above.
Specify the display interval (in seconds) between
repeated executions of diagShow. The default value
if no operand is specified or operand value is 0 is to
print the information once only. This operand is
optional.
Specify the slot to display. If no slot is specified this
command executes on all slots in the logical switch.
This operand is optional.
Specify a list of user ports to display. This operand is
optional.
Specify a list of blade ports to display. This operand is
optional.
If value is set to none zero, then the diagnostics status
for the blade ports specified in use_bports will be
displayed, otherwise the UI ports specified in
-uports is displayed. The default value is 0. This
operand is optional.
