   Table 1 Parameter description

   Parameter	Description
   Traffic Scrubbing Level	If the DDoS bandwidth on an IP address exceeds the configured scrubbing level, CNAD is triggered to scrub attack traffic. You are advised to set a value closest to, but not exceeding, the purchased bandwidth.
   Defense Mode	If the traffic reaches the specified scrubbing level, traffic scrubbing is triggered. Loose: Scrubbing is triggered when the traffic reaches three times of the scrubbing level. Normal: Scrubbing is triggered when the traffic reaches twice the scrubbing level. Strict: Scrubbing is triggered when the traffic reaches the scrubbing level.
