There are certain guidelines that you should consider before creating a LIF.
Consider the following points while creating a LIF:
- In data LIFs used for file services, the default data protocol options are NFS and CIFS.
- In node-management LIFs, the default data protocol option is set to none and the firewall policy option is automatically set to mgmt.
You can use such a LIF as a Vserver management LIF. For more information about using a Vserver management LIF to delegate Vserver management to Vserver administrators, see the Clustered Data ONTAP System Administration Guide for Cluster Administrators.
- In cluster LIFs the default data protocol option is set to none and the firewall policy option is automatically set to cluster
- You use FlexCache to enable caching to a 7-Mode volume that exists outside the cluster.
Caching within the cluster is enabled by default and does not require this parameter to be set. For information about caching a FlexVol volume outside the cluster, see the Data ONTAP Storage Management Guide for 7-Mode.
- FC LIFs can be configured only on FC ports. iSCSI LIFs cannot coexist with any other protocols. For more information about configuring the SAN protocols, see the Data ONTAP SAN Administration Guide for Cluster-Mode.
- NAS and SAN protocols cannot coexist on the same LIF.
- The firewall policy option associated with a LIF is defaulted to the role of the LIF except for a Vserver management LIF.
For example, the default firewall policy option of a data LIF is data. For more information about firewall policies, see the Clustered Data ONTAP System Administration Guide for Cluster Administrators.
- Avoid configuring LIFs with addresses in the 192.168.1/24 and 192.168.2/24 subnets. Doing so might cause the LIFs to conflict with the private iWARP interfaces and prevent the LIFs from coming online after a node reboot or LIF migration.
