Is there any way (for example using debug commands)to see Ethernet level information in incoming Ethernet frames.
For example I have Fast Ethernet interface in my router. I would like to debug, what information is receiving this interface.
Debug ip packet details show only information starting from IP level (e.g Source IP, Destination IP, protocol type).
But I would like to see Ethernet level information (e.g. Destination MAC, Source MAC).
Is the any way to do this from the Router CLI interface?

This is pure theoretical question. Other solutions to solve this problem are known for me (for. example to configure mirror SPAN port on switch to which Router is connected and debug Information with PC Ethereal).
