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)

       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:

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.

cluster01::> network interface show -service-policy default-intercluster
            Logical    Status     Network            Current       Current Is

            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 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

                                              cluster01-01:e0d
         cluster01_icl02 cluster01-02:e0c   local-only      192.168.1.201/24
                            Failover Targets: cluster01-02:e0c,
                                              cluster01-02:e0d
