Issue

A cluster network switch (e.g. serial XXX, model NX3132V) displays Is Monitored: false in ONTAP, even after deletion and re-addition using standard commands.Attempts to delete and re-add the switch using:

::> system switch ethernet delete-device
::> system switch ethernet create-device -snmp-version SNMPv2c -community-or-username cshm1! -model NX3132V -type cluster-network -address IP

do not resolve the monitoring status.
