Create a Management Network

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

Create a Management Network

On the displayed page, set the following parameters:
  • Name: Enter a name for the management network.
  • Description: Optional. Enter a description for the management network.
  • L2 Network: Select an L2 network for the management network.
    Note: ZStack Cloud allows you to use an L2 network to create multiple L3 networks. However, we recommend that you do not use an L2 network to create multiple L3 networks if not for specific business needs.
    On the Select L2 Network pane, two tabs are displayed:
    • Recommended: lists L2 networks in the current zone that are not attached to an L3 network.
    • All: lists all L2 networks in the current zone.
  • Network Range Method: Select a method to add a network range for the management network. You can select IP Range or CIDR.
    If you select IP Range, you need to set the following parameters:
    • Start IP: Set a start IP address for the network range, for example, 172.20.108.100.
    • End IP: Set an end IP address for the network range, for example, 172.20.108.200.
    • 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.
    Note: When you add an IP range for an L3 network, note that:
    • The IP range cannot contain gateway IP addresses in the format of xxx.xxx.xxx.1, broadcast addresses in the format of xxx.xxx.xxx.255, or network addresses in the format of xxx.xxx.xxx.0.
    • The IP range of a private network cannot overlap with the IP range of a public network used to create a vRouter offering or of a management network.

    If you select CIDR, you need to set the following parameters:
    • CIDR: Set a CIDR block for the management network, for example, 192.168.1.1/24.
    • Gateway: Set a gateway for the management network, for example, 192.168.1.1.
      Note:
      • You can use the first or last IP address in the specified CIDR block as the gateway.
      • If left blank, the first IP address in the specified CIDR block is used as the gateway.
    Note: When you add a CIDR block for an L3 network, note that:
    • The CIDR block cannot contain the link-local address 169.254.0.0/16.
    • The CIDR block of a private network cannot overlap with the IP range of a public network used to create a vRouter offering or of a management network.

Considerations

Make sure that the network range of the public network is different from the network range of the management network when you create a vRouter offering.
