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 . 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.
- IP Range:
- 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.
- IP Range:
- 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.
- Software: ZStack-vRouter-5.4.0.vmdk
- Download address: Click here.
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.
- IP Range:
- 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 . 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:
Note:
|
| 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.) |
