How to see the clockrate on a serial interface?

Is there any command that shows me the

clockrate that I really got from the

provider. With "show controller S0/0" for example I can see that tx and rx clock is detected but not the clock-rate.

How is the "Available Bandwidth xxxx kilobits/sec" calculated?

Re: How to see the clockrate on a serial interface?

If it's a true serial interface, you should see a clockrate. If it's a serial interface created by a fractional T1/E1 interface, you'll just see that clocks are detected. The "clockrate" in that case should be identical to 56/64k times the number of channels you have turned up. The rate at the other end should be identical, otherwise, your connection won't work. If you feel you're being shorted on bandwidth, check elsewhere. "Available bandwidth" is how much bandwidth is remaining available be RSVP-reserved on the interface. If you've configured RSVP to be on by "ip rsvp bandwith XXX", it's XXX minus any RSVP reservations you have. If you haven't turned on RSVP, it's meaningless.
