Configure the Maximum Rate of DHCP Messages
To prevent DHCP packets being used as a DoS attach when DHCP snooping is enabled the snooping
application enforces a rate limit for DHCP packets received on untrusted interface. DHCP snooping
monitors the receive rate on each interface separately. If the receive rate exceeds a configurable limit,
DHCP snooping brings down the interface. The user must do “no shutdown” on this interface to further
work with that port.
CLI: Configuring the Maximum Rate of DHCP Messages
Control the maximum rate of DHCP messages.
