An administrator has created a Nutanix managed network, and assigned it a VLAN ID of 512.
Several VMs have been created, and the administrator notices that the VMs can successfully communicate with other VMs on that VLAN, provided they are on the same host, but cannot communicate with VMs that reside on different hosts in the cluster.
What is most likely the cause of this issue?
The most likely cause of this issue is that the VLAN was not created on the upstream switches. When VMs on different hosts in the cluster are unable to communicate over the same VLAN, it usually indicates that the network configuration is incomplete. In this case, even though the VLAN is configured on the Nutanix environment, it also needs to be configured on the physical network infrastructure (upstream switches) to ensure proper communication between hosts.
