Hello,

I need to sniff BPDU packets passing through my network,
although I am not an experienced user and need help on how I would go about. 
Thanks in advance to all the folks on the user list

cheers,

You actually have a bigger problem. (nit picking: technically, they are bdpu frames and not packets).
The problem with BPDU's is that they don't just go on and on and on. You have to capture it at each and every subnet. 

Find the root bridge, then starting going down the tree from there.
