Hi Thor:
Yes - you can. I don't know that I know absolutely all ways that you could
use it independently. However, if you just configure - for example -
"l2protocol-tunnel cdp" on an access port - it does get tunneled - I just
think that the other end would have to be in dot1q-tunnel mode for the
remote end to receive it those tunneled packets. You should be able to
verify it if you do a "show spanning-tree vlan x" you would see "P2P Edge"
on the port you've configured it on. Be careful if you try it with STP,
though - that could cause some problems.
