You can configure intercluster LIFs on ports shared with the data network. Doing so reduces the number of ports you need for intercluster networking.
Procedure
-
List the ports in the cluster:network port show
For complete command syntax, see the man page.
The following example shows the network ports in
cluster01:
cluster01::> network port show

Create intercluster LIFs on the system SVM:
Option |
Description |
In ONTAP 9.6 and later: |
network interface create -vserver system_SVM -lif LIF_name -service-policy default-intercluster -home-node node -home-port port -address port_IP -netmask netmask |
In ONTAP 9.5 and earlier: |
network interface create -vserver system_SVM -lif LIF_name -role intercluster -home-node node -home-port port -address port_IP -netmask netmask |
For complete command syntax, see the man page.
The following example creates intercluster LIFs
cluster01_icl01 and
cluster01_icl02:
cluster01::> network interface create -vserver cluster01 -lif cluster01_icl01 -service-
policy default-intercluster -home-node cluster01-01 -home-port e0c -address 192.168.1.201
-netmask 255.255.255.0
cluster01::> network interface create -vserver cluster01 -lif cluster01_icl02 -service-
policy default-intercluster -home-node cluster01-02 -home-port e0c -address 192.168.1.202
-netmask 255.255.255.0
- Verify that the intercluster LIFs were created:
Option |
Description |
In ONTAP 9.6 and later: |
network interface show -service-policy default-intercluster |
In ONTAP 9.5 and earlier: |
network interface show -role intercluster |
For complete command syntax, see the man page.

- Verify that the intercluster LIFs are redundant:
Option |
Description |
In ONTAP 9.6 and later: |
network interface show –service-policy default-intercluster -failover |
In ONTAP 9.5 and earlier: |
network interface show -role intercluster -failover |
For complete command syntax, see the man page.
The following example shows that the intercluster LIFs
cluster01_icl01 and
cluster01_icl02 on the
e0c port will fail over to the
e0d port.
cluster01::> network interface show -service-policy default-intercluster –failover
