Caveats

It should be noted that some (and perhaps most) devices may not permit simultaneous transmit and/or receive of message packets during diagnostics. Unless data is flushed from internal buffers, for example, corruption or loss of user data might occur. Further, it is expected that the diagnostics tests would require setting the device to an initial known state. For that reason, the device is placed in a “ready” state prior to test, likely causing packet transmit and/or receive to be held off. This may, in turn, cause established connections to time out and management notices to be sent.

In general, device diagnostics should be used with great care and with full understanding of the potential impact to packet transmit and/or receive. It ...
