You can configure intercluster LIFs on ports shared with the data network. Doing so reduces the number of ports you need for intercluster networking. |
You can configure intercluster LIFs on ports shared with the data network. Doing so reduces the number of ports you need for intercluster networking.

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 Speed (Mbps) Node Port IPspace Broadcast Domain Link MTU Admin/Oper ------ --------- ------------ ---------------- ----- ------- ------------ cluster01-01 e0a Cluster Cluster up 1500 auto/1000 e0b Cluster Cluster up 1500 auto/1000 e0c Default Default up 1500 auto/1000 e0d Default Default up 1500 auto/1000 cluster01-02 e0a Cluster Cluster up 1500 auto/1000 e0b Cluster Cluster up 1500 auto/1000 e0c Default Default up 1500 auto/1000 e0d Default Default up 1500 auto/1000

Create intercluster LIFs on either an admin SVM (Default IPspace) or a system SVM (custom IPspace):
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
andcluster01_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.
cluster01::> network interface show -service-policy default-intercluster Logical Status Network Current Current Is Vserver Interface Admin/Oper Address/Mask Node Port Home ----------- ---------- ---------- ------------------ ------------- ------- ---- cluster01 cluster01_icl01 up/up 192.168.1.201/24 cluster01-01 e0c true cluster01_icl02 up/up 192.168.1.202/24 cluster01-02 e0c true
-
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
andcluster01_icl02
on thee0c
port will fail over to thee0d
