    ENS:Create and manage VPCs and vSwitches

    Last Updated:Feb 28, 2025

    A virtual private cloud (VPC) is a private network on the edge node. You can specify a CIDR block and configure route table entries for your VPC.

    Create and manage a VPC and a vSwitch

    Note

    Before you create a VPC and a vSwitch, make a networking plan to avoid CIDR block conflicts.

    If you want to communicate across edge nodes over an internal network, you need to make a cross-VPC network plan.

    1. Log on to the ENS console.

    2. In the left-side navigation pane, choose Network Management > Networks.

    3. Click Create Network.

    4. On the Create Network page, configure parameters in the Network and VSwitch sections. The following tables describe the parameters.

      1. Network:

        Parameter

        Description

        Node

        The edge node on which you want to create a VPC.

        Name

        The name of the VPC.

        IPv4 CIDR Block

        • Recommended CIDR Block: Select 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16.

        • Custom CIDR Block: You can use 192.168.0.0/16, 172.16.0.0/12, and 10.0.0.0/8 as well as their subnets as the CIDR blocks of VPCs. A subnet mask must be 16 to 24 bits in length. Example: 192.168.0.0/16.

        Note

        Note: After you create a VPC, the CIDR block cannot be modified.

        Description

        The description of the VPC.

        The description can be empty. If you enter a description, it must be 2 to 256 characters in length and must start with a letter. It cannot start with http:// or https://.

        Tags

        You can add tags to a VPC for subsequent resource management.

      2. vSwitch:

        Parameter

        Description

        Name

        The name of the vSwitch.

        IPv4 CIDR Block

        The CIDR block of the VPC.

        Note

        After you create a VPC, the CIDR block cannot be modified.

        Number of Available IP Addresses

        You do not need to specify this parameter. The value is automatically calculated based on the CIDR block size.

        Description

        The description of the vSwitch.

        The description can be empty. If you enter a description, it must be 2 to 256 characters in length and must start with a letter. It cannot start with http:// or https://.

        Tags

        You can add tags to a vSwitch for subsequent resource management.

    5. Optional. If you want to create multiple vSwitches for a VPC, click Add at the bottom of the vSwitch section and configure the parameters.

      Note

      You can create up to three vSwitches for a VPC.

    6. After you create a VPC, you can modify only the name and description in the Basic Information section.

    View and manage a VPC

    1. Log on to the ENS console.

    2. In the left-side navigation pane, choose Network Management > Networks.

    3. On the Network page, you can filter VPCs by Network ID, Network Name, and edge nodeENS.

    4. Click image to associate or disassociate an ACL.

    5. Click the ID of the VPC that you want to manage in the Network ID/Name column on the Networks page to go to the VPC details page. You can also click Manage in the Actions column to go to the VPC details page.

    6. The VPC details page contains the Basic Information and Resource Information sections. The Resource Information section displays the type and quantity of resources associated with the VPC.

      1. Basic Information: Network ID, Name, Node, IPv4 CIDR Block, Status, Created At, Description, and Network ACL.

      2. Resource Information: the numbers of resources such as Instance, vSwitch, Route Table, ENI, CLB, NAT Gateway, and HAVIP. You can click a number to go to the page of the corresponding resource.

    7. After you create a VPC, you can modify only the name and description in the Basic Information section.
