Which command is used to check the ARP table on a switch?

The command "show arp" is used to check the ARP (Address Resolution Protocol) table on a switch. This command is standard across many network devices and provides insight into the MAC address to IP address mappings stored in the ARP table. Understanding the ARP table is crucial for diagnosing issues related to IP address resolution and ensuring that devices can communicate properly over the network.

When you run the "show arp" command, it typically displays a list of IP addresses alongside their associated MAC addresses, allowing network administrators to verify which devices are on the local network and troubleshoot connectivity problems effectively. The command's structure is commonly used in network operating systems, making it a reliable tool for monitoring network status.
