A managed network is a type of network that can be created on an AHV cluster and allows VMs to automatically be assigned an IP address at creation time. A managed network uses the Nutanix IP Address Management (IPAM) service, which provides DHCP and DNS functionality for the VMs on the network. A managed network can be configured with a subnet range, a default gateway, and DNS servers. The IPAM service will allocate IP addresses from the subnet range to the VMs and register their hostnames in the DNS servers. The IPAM service will also release the IP addresses when the VMs are deleted or moved to another network1.
To create a managed network on an AHV cluster, the administrator can use Prism Element or Prism Central. The steps are as follows2:
* In Prism Element, go to the Network Configuration page and click Create Network.
* In Prism Central, go to the Networks page and click Create.
* Enter a name and description for the network.
* Select Managed as the network type.
* Enter the subnet range, default gateway, and DNS servers for the network.
* Optionally, enable VLAN tagging and enter a VLAN ID for the network.
* Click Save.
