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.
