What is the effect of entering the ip dhcp snooping limit rate 6 configuration command on a switch?
- It displays the IP-to-MAC address associations for switch interfaces.
- It enables port security globally on the switch.
- It restricts the number of discovery messages, per second, to be received on the interface.
- It dynamically learns the L2 address and copies it to the running configuration.
Explanation: The ip dhcp snooping limit rate command is used on untrusted interfaces to mitigate DHCP starvation attacks. It restricts the number of DHCP discovery messages that can be received on a port every second; if the limit (in this case, 6 packets per second) is exceeded, the interface can be placed into an error-disabled state to protect the DHCP server's resources.
