 *	2) Custom setup for Ingress Rate : disabled

 *	6) SA found in ATU : Exclude from ingress rate limiting calculation if the SA of the

 *	8) Sampling Mode   : Disable the mode
 *	9) Action Mode     : Follow Limit action when there are not enough tokens to accept the

 *	10) Limit action   : Drop packets when the incoming rate exceeds the limit
 *	11) Rate type      : Rate is based on Traffic type
