Configuring VP policing
A VP is the collection of all PVCs with the same VPI value. VP policing is used to manage the maximum
bandwidth of the VP, and monitor the traffic of the inbound and outbound directions of the VP on a
physical interface. When the maximum transmission rate of the VP exceeds the specified value, the
exceeded flows are dropped. When VP policing is applied, the parameters of PVC are still valid. Packets
can be transmitted or received only when the parameters of PVC and VP policing are met. In calculating
the traffic, the LLC/SNAP, MUX, and NLPID headers are included, but the ATM cell header is not
included.

6. Re-mark the CLP flag value of
ATM cells.

By default, the CLP flag
value of ATM cells is not
re-marked.
The CLP flag value of ATM
cells is 0 or 1. The cells
with a CLP flag value of 1
are dropped first when
network congestion
occurs.
