Hi Kostas,
You cannot configure it per VC.
You only can actrivate VC shaping per line.
If enabled, all new PVCs terminating to this line/port have VC shaping enabled.
To activate it on all existing PVCs, you either have to reset the card or down/up the connection.
Afterwards, you are not able to check on what PVC the VC shaping ios already enabled.
Hope this helps.
