Weird networking issue.

[Drew Weaver <drew.weaver () thenap com>]

Hi, this is kind of a newbie question but this doesn't make a whole lot of
sense :P

I have an etherstack hub connected to a FastEthernet port on a cisco 3660
router, these are the stats when I do a show int fast0/0:

5776 input errors, 5776 CRC, 2717 frame, 0 overrun, 0 ignored

Whats weird is I just cleared the counters 12 minutes ago, and already there
are almost 6000 CRC errors. This connected via a standard Cat5 ethernet
cable, I have tried replacing the cable to noavail.

Is this a fairly normal situation, If so that's great, but it seemed rather
ridiculous to me, and if it is not a normal situation, what would cause
this?

Any ideas are appreciated.
Thanks,
