Built-In Bit Error Test?

[Dan]

Archived from groups: comp.dcom.lans.ethernet (More info?)

Does ethernet have any built-in error tests that measure either bit or
frame errors? Or are there readily-available tools that would do this
on a PC? I would like to be able to detect and quantify errors using a
TCP/IP command or an ftp file transfer, without having to use a SmartBits.

TIA.

No.

NICs generally keep a count of the number of frames with bad CRCs,
but that really doesn't tell you about bit errors.

I have heard that some of the new gigabit NICs have some line-quality
tests built in, such as being able to detect the distance to cable
breaks.

Also, Fluke has some devices that can be quite useful in testing
line quality, without having to go all the way to a SmartBits.
