guidelines
This function takes effect for all the interfaces of the VLAN
controlled by the DHCP Snooping, including trust interface.
For some CPP-enabled products, CPP will restrict the rate
of DHCP packets by hardware. CCP-based rate limit takes
precedence over DHCP Snooping-based rate limit. For
CPP, please refer to specific chapters.
You can view the rate limit setting on the corresponding
interface by show ip dhcp snooping command.
