Maximum Rate of DHCP Messages 

To prevent DHCP packets being used as DoS attachments when DHCP snooping is enabled, 
the snooping application enforces a rate limit for DHCP packets received on untrusted 
interfaces. DHCP snooping monitors the receive rate on each interface separately. If the 
receive rate exceeds the configured limit, DHCP snooping brings down the interface. The 
user must specify “no shutdown” on this interface to further work with that port.
