Clock Rate Details

What governs the speed to set clock rate at? How do you know what speed to use? Todd Lammle always sets clock rate at 64000. Is 64000 the default?

The clock rate is speed of your connection that is what governs it. 64000 is the speed of a T1 which is the default for a serial interface.

is there a chart you memorized? Example- like the bandwidth chart of each media?

I always used 56000. Even on labs at school.

There is no chart I memorized. I have never used the clockrate command in a real network, only when connecting back to back in a lab situation.

Negative. A T1 has a data rate of 1.536/1.544 Mbps. 64000 is t he speed of a DS0. In real life (outside of the lab) you router pulls clocking from the line and you wont set it. Don't confuse the "clock rate" with the "bandwidth", bandwidth is used as a metric for routing and defaults to 1544Kbps on a serial interface.

In a T1 you will pull the timing or "clock" from one of the ds0 which is 64kbs.
