What information can be identified about a physical switch using CDP and LLDP in vSphere?

Using CDP (Cisco Discovery Protocol) and LLDP (Link Layer Discovery Protocol) in a vSphere environment allows for the identification of specific attributes related to physical switches that are directly connected to ESXi hosts. The correct choice accurately reflects the essential information these protocols are designed to convey.

CDP and LLDP provide detailed information about the devices connected to the network. One of the primary pieces of information communicated by these protocols includes the switch's name, which helps to identify the specific device in the network topology. Additionally, they convey the port number on the switch that is connected to the ESXi host, which is crucial for network management and troubleshooting. Finally, these protocols also report port speed and duplex settings, enabling administrators to verify configuration and diagnose performance issues effectively.

Collectively, this information is vital for managing a virtualized environment, allowing for better visibility into the network setup and fostering smoother network operations. This combination of attributes helps network and system administrators ensure optimal connectivity and performance between the VMware environment and the physical network infrastructure.
