vCenter Network Resource

This topic falls into two parts: create a vCenter network resource and manage a vCenter network resource.

On the main menu of ZStack Cloud, choose Resource Center > vCenter > Network. On the Network page, click Create Network. Then, the Create Network page is displayed.

This topic describes three vCenter network creation scenarios.

Create a public network.
Create a flat network.
Create a VPC network.

Create a Public Network

On the displayed page, set the following parameters:

Name: Enter a name for the public network.
Description: Optional. Enter a description for the public network.
L2 Network Type: Select an L2 network type as needed.
- Supported types: L2NoVlanNetwork and L2VlanNetwork.
- If you select L2VlanNetwork, enter the VLAN ID.
Switch: Enter the dvSwitch name or vSwitch name of the vCenter as needed.
Network Type: Select Public Network here.
Cluster: Select a vCenter cluster.
Network Range Method: Select a method to add a network range for the public network. You can select IP Range or CIDR.
- IP Range:
  - Start IP: Set a start IP address for the network range, for example, 172.20.58.200.
  - End IP: Set an end IP address for the network range, for example, 172.20.58.220.
  - Netmask: Set a netmask for the network range, for example, 255.255.0.0.
  - Gateway: Set a gateway for the network range, for example, 172.20.0.1.
- CIDR: Set a CIDR block for the public network, for example, 192.168.1.1/24.
DHCP Service: Optional. Choose whether to enable the DHCP service.
Note: vCenter public network does not support DHCP services. You need to manually assign an IP address to a VM instance.

Create a Flat Network

On the displayed page, set the following parameters:

Name: Enter a name for the flat network.
Description: Optional. Enter a description for the flat network.
L2 Network Type: Select an L2 network type as needed.
- Supported types: L2NoVlanNetwork and L2VlanNetwork.
- If you select L2VlanNetwork, enter a VLAN ID.
Switch: Enter the dvSwitch name or vSwitch name of the vCenter as needed.
Network Type: Select Flat Network here.
Cluster: Select a vCenter cluster.
Network Range Method: Select a method to add a network range for the public network. You can select IP Range or CIDR.
- IP Range:
  - Start IP: Set a start IP address for the network range, for example, 172.20.58.100.
  - End IP: Set an end IP address for the network range, for example, 172.20.58.120.
  - Netmask: Set a netmask for the network range, for example, 255.255.0.0.
  - Gateway: Set a gateway for the network range, for example, 172.20.0.1.
- CIDR: Set a CIDR block for the flat network, for example, 192.168.1.1/24.
DHCP Service: Optional. Choose whether to enable the DHCP service.
Note: vCenter flat network does not support DHCP services. You need to manually assign an IP address to a VM instance.

Create a VPC Network

Before you begin:

To create a vCenter VPC network, make sure that a ZStack Cloud management node and a vCenter host can communicate with each other.
To create a vCenter VPC network, you need to prepare a VPC vRouter in the Network Resource in advance.
Note: ZStack Cloud provides users with dedicated vCenter vRouter images. You can find the download address of the latest vRouter image on the ZStack Cloud official website.

On the displayed page, set the following parameters:

Name: Enter a name for the VPC network.
Description: Optional. Enter a description for the VPC network.
L2 Network Type: Select an L2 network type as needed.
- Supported types: L2NoVlanNetwork and L2VlanNetwork.
- If you select L2VlanNetwork, enter a VLAN ID.
Switch: Enter the dvSwitch name or vSwitch name of the vCenter as needed.
Network Type: Select VPC Network here.
Cluster: Select a vCenter cluster.
VPC vRouter: Select a VPC vRouter.
Network Range Method: Select a method to add a network range for the public network. You can select IP Range or CIDR.
- IP Range:
  - Start IP: Set a start IP address for the network range, for example, 172.20.58.200.
  - End IP: Set an end IP address for the network range, for example, 172.20.58.220.
  - Netmask: Set a netmask for the network range, for example, 255.255.0.0.
  - Gateway: Set a gateway for the network range, for example, 172.20.0.1.
- CIDR: Set a CIDR block for the VPC network, for example, 192.168.1.1/24.
DHCP Service: Optional. Choose whether to enable the DHCP service. The DHCP service is enabled by default.
DHCP IP: Optional. Set an IP address for the DHCP server.
NIC Type: Select the NIC type for the VPC network.

Manage a vCenter Network

On the main menu of ZStack Cloud, click Resource Center > vCenter > Network. Then, the Network page appears.

The following table lists the actions that you can perform on a vCenter network.

Action	Description
Create vCenter Network	Create a vCenter network. Network type includes public network, flat network, and VPC network.
Edit vCenter Network	Edit the name and description of the vCenter network.
Add Network Range	Add a network range for the vCenter network. An IPv4 public network supports IP range and CIDR. Flat networks and VPC networks only support IP range.
Set Sharing Mode	Set the sharing mode of a resource. The platform provides the following sharing modes: Share Globally: Shares the resource to all projects and accounts. Share to Specified Projects/Accounts: Shares the resource with specified projects and accounts. Not Share: Revokes the resource from projects and accounts to which the resource is shared. If you set Sharing Mode to Not Share for a resource, other projects and accounts cannot use the resource. Note: If you change the Sharing Mode setting of a resource from Share Globally to Share to Specified Projects/Accounts, the resource is visible only to the specified projects or accounts the resource is shared to. If the resource that you share to projects orthe specified accounts has been used by these projects or accounts and then you change the Sharing Mode of the resource, the change does not take effect on the projects or accounts. They can reverse and use the resource until it is released.
Delete vCenter Network	Deleting a vCenter network resource also deletes local records. Your actual network resources on your remote vCenter will not be affected. (Deleting a vCenter network detaches the corresponding NIC from the vCenter VM instance.)
