When a transport node is configured on a VDS host switch, some network parameters can only be configured in vCenter Server.
The following requirements must be met to install NSX-T on a VDS host switch:
- vCenter Server 7.0 or a later version
- ESXi 7.0 or a later version
The created VDS switch can be configured to centrally manage networking for NSX-T hosts.
- In vSphere:
- Create a VDS switch.
- Set MTU to at least 1600
- Add ESXi hosts to the switch. These hosts are later prepared as NSX-T transport nodes.
- Assign uplinks to physical NICs.
- Create a VDS switch.
- In NSX-T:
- When configuring a transport node, map uplinks created in NSX-T uplink profile with uplinks in VDS.
For more details on preparing a host transport node on a VDS switch, see the NSX-T Data Center Installation Guide.
The following parameters can only be configured in a vCenter Server on a VDS backed host switch:
Configuration | VDS | NSX-T | Description |
---|---|---|---|
MTU | In vCenter Server, set an MTU value on the switch.
Note: A VDS switch must have an MTU of 1600 or higher.
In vCenter Server, select VDS, click . |
Any MTU value set in an NSX-T uplink profile is overriden. | As a host transport node that is prepared using VDS as the host switch, the MTU value needs to be set on the VDS switch in vCenter Server. |
Uplinks/LAGs | In vCenter Server, configure Uplinks/LAGs on a VDS switch. In vCenter Server, select VDS, click . | When a transport node is prepared, the teaming policy on NSX-T is mapped to uplinks/LAGs configured on a VDS switch.
Note: A transport node prepared on an N-VDS switch, the teaming policy is mapped to physical NICs.
|
As a host transport node that is prepared using VDS as the host switch, the uplink or LAG are configured on the VDS switch. During configuration, NSX-T requires teaming policy be configured for the transport node. This teaming policy is mapped to the uplinks/LAGs configured on the VDS switch. |
NIOC | Configure in vCenter Server. In vCenter Server, select VDS, click . |
NIOC configuration is not available when a host transport node is prepared using a VDS switch. | As a host transport node that is prepared using VDS as the host switch, the NIOC profile can only be configured in vCenter Server. |
Link Layer Discovery Protocol (LLDP) | Configure in vCenter Server. In vCenter Server, select VDS, click . |
LLDP configuration is not available when a host transport node is prepared using a VDS switch. | As a host transport node that is prepared using VDS as the host switch, the LLDP profile can only be configured in vCenter Server. |
Add or Manage Hosts | Manage in vCenter Server. In vCenter Server, go to |
Prepared as transport nodes in NSX-T. | Before preparing a transport node using a VDS switch, that node must be added to the VDS switch in vCenter Server. |
After preparing a host transport node with VDS as a host switch, the host switch type displays VDS as the host switch. It displays the configured uplink profile in NSX-T and the associated transport zones.
In vCenter Server, the VDS switch used to prepare NSX-T hosts is created as an NSX Switch.
