This read-write value, in kilobits per second, caps the rate at which redirected DoS attack packets are forwarded, with 0 meaning no rate limit is applied. An admin sets this to prevent a redirect action from itself overwhelming the capture port or downstream analysis tool during a large attack, and like the other redirect-related columns it can only be changed once the row is enabled, set to redirect, with a redirect port specified. For example, an admin might set this to 1000 to cap redirected attack traffic at 1 Mbps, rather than leaving it unlimited at the default value of 0.
