You would be correct. We configure our switches to auto so the
customer can choose their favorite LMI. Some providers force you to use
ANSI which wil not provide CIR, hmm I wonder why

Long Answer:

looks at whay YOU have configured the bandwidth as. If you for instant

Port speed is the speed of the physical connection going into your site. So
for example, you may purchase at T1 connection from your location to ATT's
frame relay network. So your port speed is that of a T1.
A PVC is Permanent Virtual Circuit and used to connect your site, via the
frame relay
Port Speed - The connection to the providers network. Physically limits the
maximum amount of data you can push to the provider.
CIR - Committed Information Rate - The amount of data the provider
guarantees (by contract) to transport for you in a given amount of time.
PVC Speed - ? You've got

It may be bi-directional CIR, meaning 32kb one direction, 56kb the other.
Many service providers offer this type of configuration.
CIR is what he is guaranteed, anything above that might not be available.
I'm not aware of any service providers that currently implement frame relay

Actually, that minor point is what I meant...

Hi,

Hello,
CIR has no effect on routing. If you set the bandwidth
parameter to match your CIR and are using a routing
protocol that uses bandwidth in it's calculation, then
routing will reflect that. 'show interface' will show
what the bandwidth value is.

CIR is the average speed you'll transmit overall. In addition to this, you
can burst (Bc) up to, in your example, another 128K (256K total) for a
predefined period of time (usually about 1 second). Be designates all those
packets above the Bc; these are marked DE and will be discarded if
