Are you the DCE end??? Unless you are, you won't be placing a clock
rate on the interface.
The bandwidth statement is most expected when the line is less than T1
rate.
Wan interface default bandwidth is T1.

Subject: Clock Rate question
Basic Question (I hope)...
Does the clock rate command specify the speed of the link? I know that
the
bandwidth command is used only for higher layer protocols like OSPF and
EIGRP for metric calculation, and has no real impact on the speed of the
link.
I've read that the clock rate command does specify the speed (in bits
per
second), but here's my problem: The carrier (Cablevision Lightpath) does
not
provide clocking on their T's. So I had one of the routers provide
clock.
Here were my choices:
-------------------------------------------------------------------
ACL-MC3810(config-)#clock rate ?
Speed (bits per second)
1200
2400
4800
9600
19200
38400
56000
64000
72000
125000
148000
250000
500000
800000
1000000
1300000
2000000
4000000
<300-4000000> Choose clockrate from list above
line Use line clock
network Use PLL clock
-------------------------------------------------------------------
As you can see nothing matches exactly with a full T1. 148000 seems to
be
the best match. Is this correct? Does this mean that the speed will be
1.48
Mb/s?
Thanks in advance. Any clock rate information is appreciated. CCO is
kind of
weak on this subject.
