Follow these steps to replace your CN1610 (CL1) switch with a Nexus 3232C (C1) switch.

Steps

Verify the cluster's status:

network interface show -role cluster

Show example

The following example shows that the required cluster LIFs have been migrated to the appropriate cluster ports hosted on cluster switch C2:

cluster::*> network interface show -role cluster
(network interface show)
         Logical    Status      Network        Current  Current  Is
Vserver  Interface  Admin/Oper  Address/Mask   Node     Port     Home

         n1_clus2   up/up       10.10.0.2/24   n1       e0b      true
         n1_clus3   up/up       10.10.0.3/24   n1       e0c      true
         n1_clus4   up/up       10.10.0.4/24   n1       e0c      false
         n2_clus1   up/up       10.10.0.5/24   n2       e0b      false
         n2_clus2   up/up       10.10.0.6/24   n2       e0b      true
         n2_clus3   up/up       10.10.0.7/24   n2       e0c      true
         n2_clus4   up/up       10.10.0.8/24   n2       e0c      false

Shut down the node ports that are connected to CL1 on all of the nodes:

network port modify -node node-name -port port-name -up-admin false

Show example

The following example shows specific ports being shut down on nodes n1 and n2:

cluster::*> network port modify -node n1 -port e0a -up-admin false
cluster::*> network port modify -node n1 -port e0d -up-admin false
cluster::*> network port modify -node n2 -port e0a -up-admin false
cluster::*> network port modify -node n2 -port e0d -up-admin false

Shut down the ISL ports 24, 31, and 32 on the active 3232C switch C2.

For more information on Cisco commands, see the guides listed in the Cisco Nexus 3000 Series NX-OS Command References.
Show example
The following example shows ISLs 24, 31, and 32 being shut down on the active 3232C switch C2:
C2# configure C2(config)# interface ethernet 1/24/1-4 C2(config-if-range)# shutdown C2(config-if-range)# exit C2(config)# interface ethernet 1/31-32 C2(config-if-range)# shutdown C2(config-if-range)# exit C2(config)# exit C2#
Remove the cables that are attached to the CN1610 switch CL1 on all of the nodes.

Using the appropriate cabling, you must reconnect the disconnected ports on all the nodes to the Nexus 3232C switch C1.
Remove the QSFP28 cables from Nexus 3232C C2 port e1/24.

You must connect ports e1/31 and e1/32 on C1 to ports e1/31 and e1/32 on C2 using supported Cisco QSFP28 optical fiber or direct-attach cables.

Restore the configuration on port 24 and remove the temporary port-channel 2 on C2:

For more information on Cisco commands, see the guides listed in the Cisco Nexus 3000 Series NX-OS Command References.

Show example

The following example shows the running-configuration file being copied to the startup-configuration file:

C2# configure
C2(config)# no interface breakout module 1 port 24 map 10g-4x
C2(config)# no interface port-channel 2
C2(config-if)# interface e1/24
C2(config-if)# description 100GbE/40GbE Node Port
C2(config-if)# spanning-tree port type edge
Edge port type (portfast) should only be enabled on ports connected to a single
host. Connecting hubs, concentrators, switches, bridges, etc...  to this
interface when edge port type (portfast) is enabled, can cause temporary bridging loops.
Use with CAUTION

Edge Port Type (Portfast) has been configured on Ethernet 1/24 but will only
have effect when the interface is in a non-trunking mode.

C2(config-if)# spanning-tree bpduguard enable
C2(config-if)# mtu 9216
C2(config-if-range)# exit
C2(config)# exit
C2# copy running-config startup-config
[] 100%
Copy Complete.

Bring up ISL ports 31 and 32 on C2, the active 3232C switch.

For more information on Cisco commands, see the guides listed in the Cisco Nexus 3000 Series NX-OS Command References.
Show example
The following example shows ISLs 31 and 32 being brought upon the 3232C switch C2:
C2# configure C2(config)# interface ethernet 1/31-32 C2(config-if-range)# no shutdown C2(config-if-range)# exit C2(config)# exit C2# copy running-config startup-config [] 100% Copy Complete.

Verify that the ISL connections are up on the 3232C switch C2.

For more information on Cisco commands, see the guides listed in the Cisco Nexus 3000 Series NX-OS Command References.

Show example

The following example shows the ISL connections being verified. Ports Eth1/31 and Eth1/32 indicate (P), meaning that both the ISL ports are up in the port-channel:

C1# show port-channel summary

        I - Individual  H - Hot-standby (LACP only)

Bring up all of the cluster interconnect ports connected to the new 3232C switch C1 on all of the nodes:

network port modify -node node-name -port port-name -up-admin true
Show example
The following example shows all of the cluster interconnect ports connected to the new 3232C switch C1 being brought up:
cluster::*> network port modify -node n1 -port e0a -up-admin true cluster::*> network port modify -node n1 -port e0d -up-admin true cluster::*> network port modify -node n2 -port e0a -up-admin true cluster::*> network port modify -node n2 -port e0d -up-admin true

Verify the status of the cluster node port:

network port show -role cluster

Show example

The following example shows output that verifies that the cluster interconnect ports on nodes n1 and n2 on the new 3232C switch C1 are up:

cluster::*> network port show -role cluster
       (network port show)
