Dot1q Tunnels & l2protocol-tunnelling question
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.
