"clockrate" is the command you would specify in a lab environment to make a serial
interface provide clocking for a link. In a normal production environment, the
provider would provide the clock and you wouldn't have to set this.
"bandwidth," on the other hand, is a configurable parameter which the router uses in
determining the "attractiveness" of the link, especially when you're using IGRP or
EIGRP. For example, say you've got a 64k link - not very attractive, right? Well,
Cisco routers, unless you tell them otherwise via the "bandwidth" command, will assume
that every serial interface is running at T1 speed. This will make your 64k link have
a lower metric in (E)IGRP than it really should have. It will also affect your load
and utilization counters as well. When you set the bandwidth parameter to 64k (which
is in accordance with the link's actual speed), the (E)IGRP values will be adjusted
accordingly, and more accurate routing will take place.
Hope this helps.
