What is the command to show the ARP table on a Cisco device?

The command to show the ARP table on a Cisco device is "show arp" because this is the standard command used in Cisco IOS (Internetwork Operating System) to display the contents of the Address Resolution Protocol (ARP) cache. The ARP table maps IP addresses to their corresponding MAC (Media Access Control) addresses, which is essential for device communication within a local area network.

Using "show arp" will produce a list of the IP addresses the device has resolved to MAC addresses along with the interface through which these addresses are reachable. This functionality is crucial for troubleshooting network connectivity issues and understanding the mapping of IP addresses to physical devices on the network.

Other commands listed do not conform to Cisco IOS command structure or syntax. For instance, "display arp," "list arp table," and "view arp" may be commands in other operating systems or devices but are not valid within the Cisco IOS environment. Thus, they would not yield the desired ARP table information on a Cisco device.
