Usage guidelines
This command enables the DHCP server to generate DHCP logs and send them to the information

center, see System Management Configuration Guide.
As a best practice, disable this feature if the log generation affects the device performance or
reduces the address allocation efficiency. For example, this situation might occur when a large
number of clients frequently come online or go offline.
