Description
Use this command to isolate problems to a single replaceable element and isolate
problems to near-end terminal equipment, far-end terminal equipment, or
transmission line. Diagnostics can be executed every day, and also on demand to
troubleshoot a failure.
This command verifies the intended functional operation of the switch by sending
frames from port M's transmitter, and looping the frames back via an external
fiber cable into port M's receiver; thus exercising all the switch components from
the main board to the GBIC to the fiber cable to the SFPs (of the devices and the
switch) and back to the main board.
The cables and SFPs connected should be of the same technology: meaning a
short wavelength SFP (switch) port is connected to another short wavelength SFP
(device) port using a short wavelength cable; and a long wavelength port is
connected to a long wavelength port; and a copper port is connected to a copper
port.
