Before you install the NX-OS software and the Reference Configuration File (RCF), follow this procedure.
The examples in this procedure use the following switch and node nomenclature:
-
The names of the two Cisco switches are cs1 and cs2.
-
The node names are cluster1-01 and cluster1-02.
-
The cluster LIF names are cluster1-01_clus1 and cluster1-01_clus2 for cluster1-01 and cluster1-02_clus1 and cluster1-02_clus2 for cluster1-02.
-
The
cluster1::*>prompt indicates the name of the cluster.
The procedure requires the use of both ONTAP commands and Cisco Nexus 9000 Series Switches commands; ONTAP commands are used unless otherwise indicated.
-
If AutoSupport is enabled on this cluster, suppress automatic case creation by invoking an AutoSupport message:
system node autosupport invoke -node * -type all -message MAINT=x hwhere x is the duration of the maintenance window in hours.
The AutoSupport message notifies technical support of this maintenance task so that automatic case creation is suppressed during the maintenance window. -
Change the privilege level to advanced, entering y when prompted to continue:
set -privilege advancedThe advanced prompt (
*>) appears. -
Display how many cluster interconnect interfaces are configured in each node for each cluster interconnect switch:
network device-discovery show -protocol cdpShow example
cluster1::*> network device-discovery show -protocol cdp Node/ Local Discovered Protocol Port Device (LLDP: ChassisID) Interface Platform ----------- ------ ------------------------- ----------------- -------- cluster1-02/cdp e0a cs1 Eth1/2 N9K-C9336C e0b cs2 Eth1/2 N9K-C9336C cluster1-01/cdp e0a cs1 Eth1/1 N9K-C9336C e0b cs2 Eth1/1 N9K-C9336C 4 entries were displayed. -
Check the administrative or operational status of each cluster interface.
-
Display the network port attributes:
network port show -ipspace ClusterShow example
cluster1::*> network port show -ipspace Cluster Node: cluster1-02 Speed(Mbps) Health Port IPspace Broadcast Domain Link MTU Admin/Oper Status --------- ------------ ---------------- ---- ---- ----------- ------ e0a Cluster Cluster up 9000 auto/10000 healthy e0b Cluster Cluster up 9000 auto/10000 healthy Node: cluster1-01 Speed(Mbps) Health Port IPspace Broadcast Domain Link MTU Admin/Oper Status --------- ------------ ---------------- ---- ---- ----------- ------ e0a Cluster Cluster up 9000 auto/10000 healthy e0b Cluster Cluster up 9000 auto/10000 healthy 4 entries were displayed. -

Verify the connectivity of the remote cluster interfaces:
You can use the network interface check cluster-connectivity command to start an accessibility check for cluster connectivity and then display the details:
network interface check cluster-connectivity start and network interface check cluster-connectivity show
cluster1::*> network interface check cluster-connectivity start
NOTE: Wait for a number of seconds before running the show command to display the details.
cluster1::*> network interface check cluster-connectivity show

For all ONTAP releases, you can also use the cluster ping-cluster -node <name> command to check the connectivity:
cluster ping-cluster -node <name>
cluster1::*> cluster ping-cluster -node local
