Hi,

Try shaping down a little more, roughly 10%. I do know that earlier IOS did not always take into account the overhead in the ATM cell when shaping. I have seen this several times in the past though admittedly not in 12.3.

The values listed for cells/seconds in "show atm vc <name>" are correctly calculated for 53 bytes/cell (full size). Like this:

Cisco-M-XIV>sh atm vc sp1-936 ATM2/0.129: VCD: 46, VPI: 15, VCI: 129, Connection Name: sp1-936 UBR, PeakRate: 2150 (5071 cps) ^^^^ (PVC configured to "ubr 2150" instead of the 'documented' value of "ubr 2303", so that the customers won't suffer while we argue with the Telco)

So are you telling me that earlier IOSes sometimes used 48 bytes for calculating cells/s., or that the displayed values are wrong?
