The policing option, when enabled, applies only for ingress traffic. Similarly, the shaping option, if enabled, applies only for egress traffic. For example, if a traffic descriptor has both options, policing and shaping enabled, the policing option is enforced for the ingress traffic, while the shaping option is enforced for the egress traffic. The policing option is valid for all service categories. The following ATM service category conformance definitions are supported:
P0_1 — CBR, UBR
P0_1andS0_1 — VBR.1
P0_1andS0 — VBR.2
P0_1andS0_Tag — VBR.3
