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.

1. 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
   

2. 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 
   

3. 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

4. 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
   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
