The bandwith command if for routing protocols only, not for layer1 bandwith/spe
ed nor to indicate the rate of the line clock. You may have a clock rate of 640
00 and bandwith of 128k; most of the time you may want to set both at the same
rate in order for the routing protocol to work properly and calculate a "real"
metric for that link,
Some other times you may need to change that bw value, like in a multipoint sub
-if with EIGRP not to overflow the low speed PVCs whereas you have to keep the
clockrate according to the provided clock. In a real scenario, most of the time
s you don't have to deal with clockrates in the interfaces (usually DTEs for en
dpoints) since you take the clock from internal line and leave that job to the
csu/dsu.
For the lab, you may configure the clockrate as you wish as long as both ends m
atch. Just keep in mind that the bw will be responsable for the routing protoco
l decisions ...

Subject: What is relation between clockrate and bandwidth? Common port
speed 1544000, but no clock rate like
On my routers, I do not have the option of choosing a clock rate anywhere near
1544000 (the closest rate is 1300000), yet in countless scenarios (like Solie's
) we set the frame relay cir to 1544000. How can we have a port speed of 15440
00 when that is never an option on our routers as a clockspeed.
Could someone explain this.
