Deriving serial interface clock rate on DTE side

Hi all,

Is there a way, on the DTE side, to figure out the clock rate on a
synchronous serial interface?

I'm sure I've seen the clock rate included in "show controllers
<interface>" output on some IOS/platforms, but I can't remember which.

In the real world, it would be nice to be able to verify the access
rate (clock rate) on serial interfaces w/Frame Relay encapsulation
without relying on best guesses through throughput testing.

Is it buried somewhere in "sh controllers" output, a debug? something
else? Or am I going crazy? It seems odd that this information wouldn't
be available, somehow, since the router _must_ know it.

cheers,
Dale
