A network administrator enters the following commands on the switch SW1.
SW1(config)# interface range fa0/5 – 10
SW1(config-if)# ip dhcp snooping limit rate 6
What is the effect after these commands are entered?
- FastEthernet ports 5 through 10 can receive up to 6 DHCP discovery messages per second.
- FastEthernet ports 5 through 10 can receive up to 6 DHCP messages per second of any type.
- If any of the FastEthernet ports 5 through 10 receive more than 6 DHCP messages per second, the port will be shut down.
- If any of the FastEthernet ports 5 through 10 receive more than 6 DHCP messages per second, the port will continue to operate and an error message will be sent to the network administrator.
Answers Explanation & Hints: When DHCP snooping is being configured, the number of DHCP discovery messages that untrusted ports can receive per second should be rate-limited by using the ip dhcp snooping limit rate interface configuration command. When a port receives more messages than the rate allows, the extra messages will be dropped.
