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 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
ande0f
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
ande0f
to the failover groupintercluster01
on the system SVMcluster01
: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 ---------------- ---------------- -------------------------------------------- Cluster Cluster cluster01-01:e0a, cluster01-01:e0b, cluster01-02:e0a, cluster01-02:e0b cluster01 Default cluster01-01:e0c, cluster01-01:e0d, cluster01-02:e0c, cluster01-02:e0d, cluster01-01:e0e, cluster01-01:e0f 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.
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
andcluster01_icl02
in the failover groupintercluster01
:cluster01::> network interface create -vserver cluster01 -lif cluster01_icl01 -service- policy default-intercluster -home-node cluster01-01 -home-port e0e -address 192.168.1.201 -netmask 255.255.255.0 -failover-group intercluster01 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:
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 e0e true cluster01_icl02 up/up 192.168.1.202/24 cluster01-02 e0f 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
andcluster01_icl02
on the SVMe0e
port will fail over to thee0f
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:e0e local-only intercluster01 Failover Targets: cluster01-01:e0e, cluster01-01:e0f cluster01_icl02 cluster01-02:e0e local-only intercluster01 Failover Targets: cluster01-02:e0e, cluster01-02:e0f
