Enter the test cable-diagnostics command in any context to begin cable diagnostics for the transceiver. The diagnostic attempts to identify cable faults. The tests may take a few seconds to complete for each interface. There is the potential of link loss during the diagnostic.
Syntax:
Invokes cable diagnostics and displays the results.
Example of output from test cable-diagnostics command
HP Switch # test cable-diagnostics a23-a24
The ‘test cable-diagnostics’ command will cause a loss of link and will take a few seconds per
interface to complete.
