Creating VLANs for an SDDC
Learn how to create the VLANs that are required for a VMware Solution SDDC.
We recommend that you create a size /21 CIDR network segment in the VCN for the SDDC's networking resources. Divide the SDDC CIDR into ten segments of size /25 to use for the subnet and the nine required VLANs.
If you're enabling HCX, further divide the segment for the vSphere VLAN into two equal segments, one for vSphere and the other for HCX.
Configure the security rules for these networking resources as detailed in SDDC Security Rules. Otherwise, provisioning the SDDC fails.
Function | Description |
---|---|
NSX Edge Uplink 1 | The first of two uplinks used for communication between the VMware SDDC and Oracle Cloud Infrastructure. |
NSX Edge Uplink 2 | Reserved for future use to deploy public-facing applications on the VMware SDDC. |
NSX Edge VTEP | Used for data plane traffic between the ESXi host and NSX Edge. |
NSX VTEP | Used for data plane traffic between ESXi hosts. |
vMotion | Used for vMotion (VMware migration tool) management and workload. |
vSAN | Used for vSAN (VMware storage) data traffic. |
vSphere | Used for management of the SDDC components (ESXi, vCenter, NSX-T, and NSX Edge). |
Replication-Net | Used for the vSphere Replication engine. (VMware version 7.x only) |
Provisioning-Net | Used for virtual machine cold migration, cloning, and snapshot migration. |
HCX: (Optional) | Used for HCX traffic. Create this VLAN if you plan to enable HCX when you provision the SDDC. |
HCX requires that the vSphere VLAN has a route table rule that allows traffic to a NAT gateway attached to the VCN. See Intra-VCN Routing for more information.
Use the vlan create command and required parameters to create a VLAN:
oci network vlan create --cidr-block cidr_block --compartment-id compartment_OCID --vcn-id parent_VCN_OCID ... [OPTIONS]
For a complete list of flags and variable options for CLI commands, see the CLI Command Reference.
Run the CreateVlan operation to create a VLAN.
