Configuring intercluster LIFs on dedicated ports
You can configure intercluster LIFs on dedicated ports. Doing so typically increases the available bandwidth for replication traffic.
- 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

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

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

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.

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 -failover-group failover_group 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 -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-
