Configuring network settings

You can configure a single network interface (using IPv4 and IPv6 settings), Internet routing settings, and proxy settings.

Before you begin​

Ensure that you are a member of a user group to which the predefined Supervisor role is assigned.

Review the following considerations when choosing the interface:

  • The interface must be configured to support discovery and management. It must be able to communicate with the resource managers and managed devices.
Note:

  • If you change the Lenovo SDI Management Platform virtual-appliance IP address after connecting resource managers, Lenovo SDI Management Platform will lose communication with the managers, and the managers will appear offline. If you need to change the virtual-appliance IP address after Lenovo SDI Management Platform is up and running, ensure that all resource managers are disconnected (deleted) before changing the IP address.

  • If the network interface is configured to use Dynamic Host Configuration Protocol (DHCP), its IP address may change when the DHCP lease expires. If the IP address changes, resource managers must be disconnected (deleted) and then reconnected. To avoid this problem, change the network interface to a static IP address or ensure that the DHCP server is configured with a DHCP address that is based on a MAC address or the DHCP lease does not expire. :::

Procedure​

To configure network settings, click Administration ( ) > Networking, and then complete one or more of the following steps.

  • Configure IP settings

    You can choose to use IPv4 and IPv6 network settings from the IPv4 Configuration and IPv6 Configuration cards. Enable and modify the applicable IP configuration settings, and then click Apply.

    • IPv4 settings. You can configure the IP assignment method, IPv4 address, network mask, and default gateway.

    For the IP assignment method, you can choose to use a statically assigned IP address or obtain an IP address from a DHCP server. When using a static IP address, you must provide an IP address, network mask, and default gateway. The default gateway must be a valid IP address and must be on the same subnet as the network interface.

    If DHCP is used to obtain an IP address, the default gateway also uses DHCP.

    • IPv6 settings. You can configure the IP assignment method, IPv6 address, prefix length, and default gateway.

      For the IP assignment method, you can select to use a statically assigned IP address, configure a stateful address (DHCPv6), or automatically assign a stateless address. When using a static IP address, you must provide an IPv6 address, prefix length and gateway. The gateway must be a valid IP address and must be on the same subnet as the network interface.

  • Configure Internet routing settings

    Optionally configure Domain Name System (DNS) settings from the DNS Configuration card. Then, click Apply.

    Currently, only IPv4 addresses are supported.

    Choose whether to use DHCP to obtain the IP addresses or to specify static IP addresses by enabling or disabling DHCP DNS. If you choose to use static IP addresses, specify the IP address for at least one and up to two DNS servers.

    Specify the DNS host name and domain name. You can choose to retrieve the domain name from a DHCP server or specify a custom domain name.

    • If you choose to use a DHCP server to obtain the IP address, any changes that you make to the DNS Server fields are overwritten the next time Lenovo SDI Management Platform renews the DHCP lease.

    • When you change any DNS settings, you must manually restart the virtual machine to apply the changes.

  • Configure HTTP proxy settings

    (Optional) Enable and specify the proxy server host name, port, and optional credentials from the Proxy Configuration card. Then, click Apply.

    Note:

    • Ensure that the proxy server is set up to use basic authentication.

    • Ensure that the proxy server is set up as a non-terminating proxy.

    • Ensure that the proxy server is set up as a forwarding proxy.

    • Ensure that load balancers are configured to keep sessions with one proxy server and not switch between them. :::
