Not bothered trying to wake up the fruits here, but PeeCee's have been 
sulking.  I thought it was just typical borked Dull kit however even 
packet sniffing off the port I fail to get the magic packets.  That on 
the same switch on other identically configured ports it works :-/

We have the 'extra fun' of it being an 802.1X port but the 
'dot1x direction in' bits are in there and it *can* work...occasionally.

>From my experience, I don't have hard and fast info and it was a while 
back, the issue is linked to the switch thinking there is no spanning 
tree edge port action.  You can see a difference on working/non-working 
ports when you type 'show dot1x int <whatever> detail' and querying 
about what spanning tree is making of the situation too.

Sorry it's all vague, I looked into this about three months ago (when we 
were using 12.2(44)ish) and it's on my books for revisiting this 
summer.

At least you know you are not alone :)
