We installed the DS3 connection and the ISP provides only 20 MB bandwidth, and we run QoS modular. I was under impression that the command "bandwidth" is for QoS setup, and the command " dsu bandwidth" is layer1 setup. I have questions about the difference " bandwidth" and " dsu bandwidth". Did I configure right? Please advise.
int s1/0
ip address 192.168.1.1 255.255.255.252
bandwidth 20000
encpsulation ppp
dsu bandwidth 44210
Thanks,
Joe

Certain DSU's (external) have dip switches that
can be set for "actual" bandwith. You might try setting the dsu b/w to what you actually ordered
I'd also set the bandwidth to what was ordered, your qos will make more sense.

The interface "bandwidth" command like you have configured does not apply to QoS. It is for routing protocols like EIGRP, etc. There is also a "bandwidth" command you use under a policy-map which is used for QoS.
QoS example using bandwidth:
policy-map foo
class-map bar
bandwidth percent 30
Additionally you would need to define the class-map and apply the policy to an interface. This older document describes the use of the bandwidth command in QoS.
