but ina a test environment where you have a DCE/DTE crossover and you supply clock
rate (as required in this config), you are running that circuit at the speed you
specify in the clock rate. Test it this way: set the clock rate for 56000, then do a
ping with say 50 packets (use extended ping). Notice the speed of the "!". Change
the clock rate to 1000000 and ping again - notice the dramatic speed increase.
The bandwidth doesn't change the speed of the circuit, either in production (where
clocking is external to the router) or in test (where you have one router supply
clocking). But as mentioned below, it is important in all cases to set bandwidth to
the speed of the circuit because that is what routing protocols use to calculate their
metrics.

clock Rate and bandwidth is totally different entities, for live and
production environment clock rate is provided by the modem so you do not
need to have to key in the clock rate

If I set a clock rate of 56000 does that mean that I can not run the
interface at say t1 bandwidth?

clock rate is normally omitted if your router's DTE interface is connected
to a CSU/DSU since the modem will provide the clock rate information.
However if you are in a lab scenario whereby you are simulating a Wan by
connecting your DTE to your DCE using two Cisco cables then at the DCE end
you have to provide the clock rate in order that your serial interface can
be up and running.
However , bandwidth needs to be supplied no matter you are in lab or
practical environments because things like reliability , load etc depends on
it to work. Hope that helps

What is the diference between the "clock rate" command and the "bandwidth"
command?
Thanks
