Which command is used to see the MAC addresses for devices with each health status?

The command that is used to see the MAC addresses for devices along with their health status is "arp -a." This command displays the Address Resolution Protocol (ARP) table, which provides a mapping between IP addresses and their corresponding MAC addresses on the local network. It reflects the devices that the firewall has communicated with recently, along with their network status.

"arp -a" provides a quick way to diagnose network connectivity issues and understand which devices are currently active on the network. This command is pivotal in troubleshooting, particularly when monitoring network health and ensuring that devices are correctly communicating.

The other commands listed have different functionalities. For instance, "netstat" provides information about network connections, routing tables, and interface statistics, but does not specifically deal with MAC addresses. The "ipset" command is used to manage sets of IP addresses for firewall rules but does not show MAC addresses. The "getmac" command retrieves the MAC addresses of the local machine's network interfaces, but it does not compile information on other devices' health status within the network.

Thus, "arp -a" is the command that specifically addresses the need to view MAC addresses in conjunction with their health status among devices on the network.
