An administrator wants to utilize Network Visualization to monitor the physical and logical network on the Nutanix cluster. The first-hop switch has LLDP enabled. The network switch information is still not being displayed. What is causing this problem?

Network Visualization in Nutanix requires both LLDP (Link Layer Discovery Protocol) and SNMP (Simple Network Management Protocol) to be properly configured. While LLDP enables the discovery of directly connected devices and their capabilities, SNMP is essential for retrieving detailed switch information, port configurations, and network topology data. Without proper SNMP configuration (including community strings, access permissions, and network connectivity), the cluster cannot query and display comprehensive switch information even when LLDP is functioning.

A. ISL configuration affects inter-switch communication, not cluster-to-switch visibility for Network Visualization.

C. br0 and br1 are default bridges in AHV; their absence would cause broader networking issues beyond visualization.

D. RDMA-enabled NICs don't prevent Network Visualization from displaying switch information when properly configured.
