Acceptable test faciltiy losses on Alliedware Switches

What are the acceptable test facility losses (Rx bad) and duration, specifically when using the interface loop back test?

Fundamentally, the loop back test should find zero errors, i.e 100% good packets.  The IEEE standards state that the error rate on Ethernet should be about 1 bit in every 10^13 (1 in 10 to the power of 13).  That equates to about 1 errored packet in every 10^9 packets (taking the number of bits in a packet to be about 10,000)  If you are seeing significantly more than 1 error in every 10^9 packets, then that would indicate  the Ethernet interface is out of spec.
