Explanation/Reference:
Data ONTAP services may initiate network connections from a node in the cluster. For example:
AutoSupport, SNMP, time synchronization, and syslog. When a Node Management interface is configured
and available, it is preferred for these connections.
When Data ONTAP contacts name services like Active Directory, NIS, DNS, or LDAP, it prefers to initiate
these connections from Data or SVM Management interfaces belonging to the Storage Virtual Machine
(SVM).
Note: 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. The five LIF roles are:
* Cluster-management LIF
* Node-management LIF
* Cluster LIF
* Data LIF
* Intercluster LIF
