A network administrator is configuring DAI on a switch with the command ip arp inspection validate src-mac . What is the purpose of this configuration command?

  • It checks the source MAC address in the Ethernet header against the MAC address table.
  • It checks the source MAC address in the Ethernet header against the user-configured ARP ACLs.
  • It checks the source MAC address in the Ethernet header against the target MAC address in the ARP body.
  • It checks the source MAC address in the Ethernet header against the sender MAC address in the ARP body.
    Answers Explanation & Hints:

    DAI can be configured to check for both destination or source MAC and IP addresses:
    Destination MAC – Checks the destination MAC address in the Ethernet header against the target MAC address in the ARP body.
    Source MAC – Checks the source MAC address in the Ethernet header against the sender MAC address in the ARP body.
    IP address – Checks the ARP body for invalid and unexpected IP addresses including addresses 0.0.0.0, 255.255.255.255, and all IP multicast addresses.
