Prerequisites for Integrating GigaVUE V Series Nodes with NSX-T

The following are the prerequisites for integrating GigaVUE V Series Nodes with VMware NSX-T:

  • ESXi hosts must be prepared as NSX-T Data Center transport nodes by using transport node profiles.
  • ESXi hosts where workload VMs that needs to be monitored must be attached to the overlay transport zone.
  • GigaVUE‑FM supports service insertion only for overlay transport zone associated with the E-W traffic. Service insertion is not supported on VLAN transport zone associated with the N-S traffic or when the VMware NSX-T manager in federation mode.
  • Before deploying GigaVUE V Series Nodes using GigaVUE-FM, Service segment must be created in the NSX-T manager on Overlay Transport Zone. Refer to Create a Service Segment in VMware NSX-T for step-by-step instructions on how to create service segment.
  • Refer to Supported Hypervisors for VMware for supported VMware vCenter, VMware ESXi and VMware NSX-T versions.
  • Only IPv4 traffic is supported.
  • If a guest VM running on an ESXi host is connected to a VLAN segment. and that ESXi host is not configured to an Overlay Transport zone, then the traffic destined to a service VM is disrupted. Such a configuration can also cause traffic to be routed to a black hole.
  • For more detailed VMware requirements on East-West traffic monitoring, refer to the below links and select the appropriate NSX-T version.
  • Refer to Prerequisites for Integrating GigaVUE V Series Nodes with NSX-T for ESXi host resource requirement to deploy GigaVUE V Series Nodes.
  • GigaVUE V Series Node device OVA image file.

    Note:  An external HTTP(S) server for hosting the GigaVUE V Series image OVFs and VMDK file (extracted from the OVA file) when using Use External Image Option in Monitoring Domain. Refer to Create Monitoring Domain for VMware NSX-T for more detailed information on what is an external image and how to configure it.

    The GigaVUE V Series Node OVA image files can be downloaded from Gigamon Customer Portal.

Unsupported Configurations when using VMware NSX-T:

  • Service Insertion is not supported on Global NSX-T managers in federation mode. Use Local NSX-T Managers for deploying our solution in this case.
  • Service Insertion is not supported on Multi tenancy environments.
  • Multiple monitoring domains cannot be configured with same NSX-T manager.
