Traffic shaping by IP enables you to apply traffic shaping to all source IP addresses in the security policy. As well as controlling the maximum bandwidth users of a selected policy, you can also define the maximum number of concurrent sessions.

Per-IP traffic shaping enables you limit the behavior of every member of a policy to avoid one user from using all the available bandwidth - it now is shared within a group equally. Using a per-IP shaper avoids having to create multiple policies for every user you want to apply a shaper. Per-IP traffic shaping is not supported over NP2 interfaces.
