Final answer:
In Fortigate's per-IP shaper configuration, the purpose of setting the maximum bandwidth is to limit data usage per IP to ensure fair distribution of network resources.
Step-by-step explanation:
In Fortigate's per-IP shaper configuration, the purpose of setting the maximum bandwidth is to limit data usage per IP. This allows for better network management by ensuring that each IP address does not consume more bandwidth than allocated, which preserves network resources for other users. By setting a maximum bandwidth, the network administrator can prevent any single IP address from hogging all the available bandwidth and affecting the overall network performance.
For example, if a user on your network is heavily streaming video and using a lot of bandwidth, you can set a maximum bandwidth for their IP address to ensure that their usage doesn't impact other users' internet experience.
Controlling network latency, enhancing firewall security, and optimizing routing performance are not the primary purposes of setting the maximum bandwidth in Fortigate's per-IP shaper configuration.
