Just a note, I just did an additional test off another 2950 connected to
e2/1, and it works just fine there. So it's certainly an issue localized
to either e2/0 or the 2950 on that port. Any advice for testing? Could it
have something to do with the protected switchports that are enabled on
the 2950?

Thanks!
