This section explains the system requirements of various clouds.

VMware Ecosystems

The following are the VMware vCenter versions supported by the NSX Advanced Load Balancer:

Virtual Hardware Version 10


5.5, 6.0, 6.4, 6.5, or 6.7



5.5, 6.0, 6.4, 6.5, or 6.7


20.1.1 to 20.1.5

5.5, 6.0, 6.4, 6.5, 6.7, 7.0



6.0, 6.4, 6.5, 6.7, 7.0



6.0, 6.4, 6.5, 6.7, 7.0



When upgrading across releases having different virtual hardware versions, the existing SEs which are created with a previous virtual hardware versions continue to work. However, new SEs are spawned with the updated virtual hardware version.

NSX Advanced Load Balancer only works with the following switches in a vCenter Cloud:

  • Standard Virtual Switch (vSwitch)

  • Distributed Virtual Switch (vDS)

Also, the deployment of the Controller and SE OVA directly on an ESX host (for a no-access or other cloud-connector types) is not supported. They must be deployed using the vCenter UI, as the deployment requires Open Virtualization Format (OVF) properties to be configured.

  • VMXNET3 network adapter is required for SE to operate in DPDK mode in VMware.

Jumbo-Drivers Supported

Supported Drivers

Unsupported Drivers

i40e, mlx5, bnxt, vmxnet3


  • Jumbo frames are supported for non-DPDK mode and on VLAN interfaces for supported driver families. However, the jumbo frames are not supported on CSP.


    vmxnet3 interface will flap during MTU change.

  • KNI MTU cannot exceed 1500 even when NIC MTU is configured.

  • se_mtu vs global_mtu: global_mtu is an SE property that is used to configure the interface MTU. This can be used to accommodate any encapsulation overhead, that can enlarge the packet beyond the 1500 MTU.

  • You can replace global_mtu with se_mtu as se_mtu supports jumbo frame. The se_mtu configuration parameter/ field always overrides global_mtu, if configured. For instance, if you configure se_mtu to 9000, then the system does not depend on global_mtu value.

    • Note:

      The global_mtu is retained only for backward compatibility, i.e., if you configure global_mtu in an earlier release and do an upgrade, then global_mtu should still take effect unless you configure se_mtu later.
