Learn how to configure intercluster LIFs on dedicated and shared ports.

Configure intercluster LIFs on dedicated ports

You can configure intercluster LIFs on dedicated ports to increase the available bandwidth for replication traffic.

Steps

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
       e0e       Default      Default          up     1500   auto/1000
       e0f       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
       e0e       Default      Default          up     1500   auto/1000
       e0f       Default      Default          up     1500   auto/1000

Determine which ports are available to dedicate to intercluster communication:

network interface show -fields home-port,curr-port

For complete command syntax, see the man page.

The following example shows that ports "e0e" and "e0f" have not been assigned LIFs:

cluster01::> network interface show -fields home-port,curr-port
vserver lif                  home-port curr-port
------- -------------------- --------- ---------
Cluster cluster01-01_clus1   e0a       e0a
Cluster cluster01-01_clus2   e0b       e0b
Cluster cluster01-02_clus1   e0a       e0a
Cluster cluster01-02_clus2   e0b       e0b
cluster01
        cluster_mgmt         e0c       e0c
cluster01
        cluster01-01_mgmt1   e0c       e0c
cluster01
        cluster01-02_mgmt1   e0c       e0c

Create a failover group for the dedicated ports:

network interface failover-groups create -vserver <system_SVM> -failover-group <failover_group> -targets <physical_or_logical_ports>

The following example assigns ports "e0e" and "e0f" to the failover group "intercluster01" on the system SVM "cluster01":
```
cluster01::> network interface failover-groups create -vserver cluster01 -failover-group
intercluster01 -targets
cluster01-01:e0e,cluster01-01:e0f,cluster01-02:e0e,cluster01-02:e0f
```

Verify that the failover group was created:

network interface failover-groups show

For complete command syntax, see the man page.

cluster01::> network interface failover-groups show
                                  Failover
Vserver          Group            Targets

                                  cluster01-02:e0e, cluster01-02:e0f
                 intercluster01
                                  cluster01-01:e0e, cluster01-01:e0f
                                  cluster01-02:e0e, cluster01-02:e0f

Create intercluster LIFs on the system SVM and assign them to the failover group.

Command

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> -failover-group <failover_group>

For complete command syntax, see the man page.

The following example creates intercluster LIFs "cluster01_icl01" and "cluster01_icl02" in the failover group "intercluster01":

cluster01::> network interface create -vserver cluster01 -lif cluster01_icl01 -service-

cluster01::> network interface create -vserver cluster01 -lif cluster01_icl02 -service-
policy default-intercluster -home-node cluster01-02 -home-port e0e -address 192.168.1.202
-netmask 255.255.255.0 -failover-group intercluster01

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`

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:

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`

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 SVM "e0e" port will fail over to the "e0f" port.

Configure intercluster LIFs on shared data ports

You can configure intercluster LIFs on ports shared with the data network to reduce the number of ports you need for intercluster networking.

Steps

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

       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>`

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

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`

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.
