Network considerations – XClarity Management Hub 2.0

You can configure Lenovo XClarity Management Hub 2.0 to use a single network interface (eth0) for communication.

Network interface (eth0)​

XClarity Management Hub 2.0 uses a single network interface (eth0) for management and data communication. Review the following considerations before configuring the network.
  • The network interface is used for discovery and management. XClarity Management Hub 2.0 must be able to communicate with all devices that you intend to manage.
  • The network interface must be connected to the Internet, preferably through a firewall.

IPv4 address settings​

XClarity Management Hub 2.0 uses IPv4 network 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 Dynamic Host Configuration Protocol (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.

Attention
  • Network address translation (NAT), which remaps one IP address space into another, is not supported.
  • Changing the IP address of the XClarity Management Hub 2.0 virtual-appliance after the management hub is up and running will cause connectivity issues with the XClarity Orchestrator portal and all managed devices. If you need to change the IP address, disconnect management hub from the portal, and unmanage all managed devices before changing the IP address. After the IP address change is complete, reconnect management hub to the portal and re-manage the devices.
  • If the network interface is configured to use the DHCP, ensure that IP address changes are minimized by basing the DHCP address on a MAC address or configuring DHCP so that the lease does not expire to avoid communication issues. If the IP address changes when the DHCP lease expires, you must disconnect (delete) the management hub from the portal, and then connect it again.
