Tunnels and IPSec encryptions - how to check the encryption?

How to check if a GRE (or any other) tunnel is running on an encrypted IPSec connection (tunnel) ?
Under tools, there is a packet sniffer.
Launch that using the physical port through which the tunnel is leaving.
Save a few packets to a file and open it with wireshark.
There you'll see if it's encrypted or not.
