What is the effect of entering the show ip dhcp snooping binding configuration command on a switch?
- It switches a trunk port to access mode.
- It checks the source L2 address in the Ethernet header against the sender L2 address in the ARP body.
- It restricts the number of discovery messages, per second, to be received on the interface.
- It displays the IP-to-MAC address associations for switch interfaces.
Explanation: The show ip dhcp snooping binding command is used to display the DHCP snooping binding table. This table records the associations (bindings) between the source MAC addresses of devices on untrusted ports and the IPv4 addresses assigned to them by a legitimate DHCP server. It is an essential tool for verifying which clients have received DHCP information and serves as a critical database for other security features like Dynamic ARP Inspection (DAI).
