Command History
Usage Guidelines The show diagnostic post command output is the same as the show post command output.
In Catalyst 3750-X switch stacks, if you do not enter the switch number parameter with the content,
result, schedule, and switch keywords, information for all stack members is displayed.
On Catalyst 3750-X switches, the show diagnostic result switch [number | all] [detail] command output
is the same as the show diagnostic switch [number | all] [detail] command output.
On Catalyst 3560-X switches, the show diagnostic result [detail] command output is the same as the
show diagnostic switch [detail] command output.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
Examples This example shows how to display the online diagnostics that are configured on all the PoE-capable
switches in a stack:
