Test command
Tests switch module ports using internal (SerDes level), external small form-factor pluggable (SFP), and
online loopback tests. Internal and external tests require that the switch module port be placed in diagnostic
mode. See the “Set Port command” on page 34 for information about changing the port administrative state.
While the test is running, the remaining ports on the switch remain fully operational. See “Port testing” on
page 117 for more information.
