Which discovery protocol is supported for hypervisor transport nodes?

The correct choice is Link Layer Discovery Protocol (LLDP), which is a standard link-layer protocol used for network devices to advertise their identity and capabilities to each other. In the context of hypervisor transport nodes in VMware NSX-T, LLDP is essential for facilitating the communication between devices and enabling the discovery of network topology.

When hypervisor transport nodes use LLDP, they can automatically share information about their configurations and capabilities with neighboring devices. This is particularly important in virtualized environments where multiple virtual machines and networking components need to interact reliably.

While other discovery protocols like Cisco Discovery Protocol (CDP) and various non-standard protocols serve similar functions in different networking contexts, LLDP is the specific protocol that is utilized within the NSX-T architecture for hypervisor transport nodes. This adherence to an open standard ensures compatibility and interoperability across diverse network hardware and software platforms.
