Configuring intercluster LIFs on shared data ports
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 the system SVM:
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:
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:
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 Logical Home Failover Failover Vserver Interface Node:Port Policy Group -------- --------------- --------------------- --------------- -------- cluster01 cluster01_icl01 cluster01-01:e0c local-only 192.168.1.201/24 Failover Targets: cluster01-01:e0c, cluster01-01:e0d cluster01_icl02 cluster01-02:e0c local-only 192.168.1.201/24 Failover Targets: cluster01-02:e0c, cluster01-02:e0d
