Remember though, that when a sender exceeds the CIR, the frame switch
only marks the packet's DE flag. So if the frame switch is not
congested, then none of the packets will be discarded.

Hi group,
I have a cisco 2522 router that is configured as a frame relay switch. I am
trying to configure CIR on serial 4 so that if the router connected to s4 is
sending more traffic than the configured CIR, packets will be dropped at fhe
frame relay switch. I configured the CIR on the switch but it seems that the
router connected to s4 can still send traffic at rates exceeding the CIR,
and the FR switch will not drop any packet.
Can some one give an advice here?
Below is the configuration of the frame relay switch.
