You can use System Manager to create and manage network interfaces.
More information
Creating network interfaces
You can use System Manager to create a network interface or LIF to access data from Storage Virtual Machines (SVMs), manage SVMs, and to provide an interface for intercluster connectivity.
Editing network interfaces
You can use System Manager to modify the network interface to enable management access for a data LIF.
Deleting network interfaces
You can use System Manager to delete a network interface to free the IP address of the interface and use the IP address for a different purpose.
Migrating a LIF
You can use System Manager to migrate a data LIF or a cluster-management LIF to a different port on the same node or a different node within the cluster, if the port is either faulty or requires maintenance.
What LIFs are
A LIF (logical interface) is an IP address or WWPN with associated characteristics, such as a role, a home port, a home node, a list of ports to fail over to, and a firewall policy. You can configure LIFs on ports over which the cluster sends and receives communications over the network.
Roles for LIFs
A LIF role determines the kind of traffic that is supported over the LIF, along with the failover rules that apply and the firewall restrictions that are in place. A LIF can have any one of the five roles: node management, cluster management, cluster, intercluster, and data.
