Jim,
You can not verify the CIR on a Cisco Router unless you are
running Cisco LMI. If you are running Cisco LMI you will find
the CIR by performing a show frame pvc. If you aren't running
Cisco LMI then you won't be able to find out what it is set to.
As an alternative you can always test your throughput by pulling
a large file and see what kind of throughput you get. I use a
NMS called Spectrum that allows me to see the frame pvc utilization
in real time from the router's perspective, unfortunately it is
expensive and I can't recommend another. Whatever tool you do use
make sure that you measure the byte count from the show frame pvc
command.
If you don't have access to a good snmp tool then just send a
large file through and grab the byte count before and after sending
the file and don't forget to time how long it takes. The bigger
the file, the longer the sample time, the more accurate the measurement.
Remember that your PVCs throughput will be based upon your Frame
Relay provider's technology/policies. There are a million
variables that could cause your throughput to go above your CIR,
but there are only two reasons why it should will below your CIR:
1) Your CIR isn't set as high as you think it should be
2) Your Frame service isn't working correctly
In either event, if it does drop below your CIR, then you need to
contact your service provider and find out why.
HTH,
AQ
p.s. All of the above is predicated on the fact that your routers
are configured correctly. :-)
