Description
Using the pvp limit command, you can set the parameters for VP policing. Using
the undo pvp limit command, you can delete the VP policing.
By default, the VP policing is not performed.
When applying VP policing, the parameters of PVC are still valid. Only when the
parameters of PVC and VP policing are satisfied, will the packets be transmitted.
When calculating the traffic, the LLC/SNAP, MUX and NLPID headers are included,
but the ATM cell head is not included.
For the related commands, see pvc, service cbr, service vbr-nrt, and service vbr-rt,
service ubr.
