I have a number of quite long (i.e. 30 metres or more) cat5e cables strung about the place and would like to test how 'clean' they are.
It's easy enough to test their basic integrity (i.e. if all 8 wires are correctly connected) and I have done that. However I'd like to see if they are actually good enough to provide maximum performance when running gigabit. Presumably if they aren't working too well one will see errors and retries at the hardware level - is there a tool for monitoring this?
Mostly these cables have just one switch between the ends but there are a couple where there may be two switches involved.
