I recently upgraded my 4506 to IOS image:cat4000-i9s-mz.122-20.EW4.bin
However, after doing so I am unable to configure interfaces for dot1q-tunnels. I am able to set the global command, but the interface subcommands don't list dot1q-tunnel as a mode option.
I don't see a bug for this and the command sets on Cisco.com show the command should be "switchport mode dot1q-tunnel"
Anyone seen this before, or know what I am missing?
