Manage the monitoring of Ethernet Switches

In most cases, Ethernet switches are automatically discovered by ONTAP and monitored by CSHM. The Reference Configuration File (RCF) applied to the switch, among other things, enables the Cisco Discovery Protocol (CDP) and/or the Link Layer Discovery Protocol (LLDP). However, you might need to manually add a switch that is not discovered or remove a switch that is no longer in use. You can also stop active monitoring while retaining the switch in the configuration, such as during maintenance.

Create a switch entry so that ONTAP can monitor it

Use the system switch ethernet create command to manually configure and enable monitoring for a specified Ethernet switch. This is helpful if ONTAP does not add the switch automatically, or if you previously removed the switch and want to re-add it.

system switch ethernet create -device DeviceName -address 1.2.3.4 -snmp-version SNMPv2c -community-or-username cshm1! -model NX3132V -type cluster-network

A typical example is adding a switch named [DeviceName], with IP address 1.2.3.4, and SNMPv2c credentials set to cshm1!. Use -type storage-network instead of -type cluster-network if you are configuring a storage switch.

Disable monitoring without deleting the switch

If you want to pause or stop monitoring for a certain switch, but still retain it for future monitoring, modify its is-monitoring-enabled-admim parameter instead of deleting it.

For example:

system switch ethernet modify -device DeviceName -is-monitoring-enabled-admin false

This lets you preserve switch details and configuration without generating new alerts or re-discoveries.

Remove a switch you no longer need

Use system switch ethernet delete to delete a switch that has been disconnected or is no longer required:

system switch ethernet delete -device DeviceName

By default, this command succeeds only if ONTAP does not currently detect the switch through CDP or LLDP. To remove a discovered switch, use the -force parameter:

system switch ethernet delete -device DeviceName -force

When -force is used, the switch might be re-added automatically if ONTAP detects it again.
