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:

Host and Network Requirements

• Prepare ESXi hosts as NSX-T Data Center transport nodes using transport node profiles.

• Connect ESXi hosts running the workload VMs (to be monitored) to an overlay transport zone.

• Create a service segment in the NSX-T Manager on the overlay transport zone before deploying GigaVUE V Series Nodes through GigaVUE‑FM. For instructions, refer to Create a Service Segment in VMware NSX-T.

• Ensure that your deployment meets the supported versions of VMware vCenter, VMware ESXi, and VMware NSX-T. For version compatibility, refer to Supported Hypervisors for VMware.

• 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 route traffic 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.
  • For versions 3.x.x: NSX-T Data Center Requirements for East-West Traffic.
  • For versions 4.x.x: NSX Requirements for East-West Traffic.

Service Insertion Support

• GigaVUE‑FM supports service insertion only on overlay transport zones associated with east-west (E-W) traffic.

• GigaVUE‑FM does not support service insertion on:

  • VLAN transport zones associated with north-south (N-S) traffic.

  • NSX-T Managers running in federation mode.

Software and Image Requirements

• Ensure your ESXi hosts meet the resource requirements for deploying GigaVUE V Series Nodes. For details, refer to Prerequisites for Integrating GigaVUE V Series Nodes with NSX-T .

• Download the GigaVUE V Series Node OVA image file from the Gigamon Customer Portal.

Note:  If you use the External Image option in the monitoring domain, host the OVF and VMDK files (extracted from the OVA) on an external HTTP(S) server. For information, refer to Create Monitoring Domain for VMware NSX-T.

Unsupported Configurations when using VMware NSX-T:

• Service Insertion:
  • Not supported on Global NSX-T managers in federation mode. Use Local NSX-T Managers for deploying our solution.
  • Not supported on Multi tenancy environments.
• Multiple monitoring domains: Cannot configure multiple monitoring domains with the same NSX-T manager.

Refer to the following topics:

• Network Firewall Requirements
• Recommended Form Factor (Instance Types)
• Required VMware Virtual Center Privilege
• Required Roles in VMware NSX-T
• Disable Certification Validation in VMware NSX-T
• Default Login Credentials
