How do I determine the CIR on a Frame Relay Serial Connection?

[cadams]

I have several point-to-point sub serial frame-relay connections. The bandwidth is specified on each interface, however this is only to calculate a metric for OSPF. What commands can I use if any to determine the true bandwidth of the pipe?

debug frame lmi will show you the lmi messages you receive from the frame switch. Included in about every 10 of these is the PVC speed. Just keep in mind that using debug commands on a live network can be processor intensive, but I have used this command in the past without any serious ramifications.

I was apply the command but only obtain the follow and I do not find the true bandwidth my IOS is 12.0-7T:

I beleive only the cisco LMI type is capable of sending the CIR.

[juan-santamaria]

there are some form to know the real BW of the PVC , using any commands
