What information does the 'show lldp neighbors' command provide?

The command 'show lldp neighbors' is used to display information about devices that are directly connected and running the Link Layer Discovery Protocol (LLDP). This protocol enables devices to advertise their identity and capabilities on a local network. When you execute this command, it reveals details about each neighboring device, including their system name, port ID, and capabilities, among other relevant information. This makes it essential for network administrators to understand the topology of their network and to troubleshoot connectivity issues.

While the other options may present useful information in different contexts, they do not pertain to what the 'show lldp neighbors' command specifically delivers. For instance, a device's MAC address is an identifier for the device itself, not for the neighboring connections. Device configuration settings relate to the current setup and operational parameters of a device, which is distinct from neighbor discovery. The status of network interfaces reflects the operational state of the device's ports but does not provide insights into neighboring devices. Therefore, the correct understanding of the command is that it primarily focuses on all connected devices that support LLDP.
