Switches supported by ONTAP

From ONTAP 9.9.1, you can use Cisco Nexus 9336C-FX2 switches to combine storage and cluster functionality into a shared switch configuration. If you want to build ONTAP clusters with more than two nodes, you need two supported network switches.

The following Cisco shared network switches are supported.

Nexus 9336C-FX2

You can install the Cisco Nexus 9336C-FX2 switch (X190200/X190210) in a NetApp system cabinet or third-party cabinet with the standard brackets that are included with the switch.

The following table lists the part number and description for the 9336C-FX2 switch, fans, and power supplies:

Setup the switches

If you do not already have the required configuration information and documentation, you need to gather that information before setting up your shared switches.

Before you begin
  • You must have access to an HTTP, FTP or TFTP server at the installation site to download the applicable NX-OS and reference configuration file (RCF) releases.

  • You must have the required shared switch documentation.

    See Required documentation for shared switches for more information.

  • You must have the required controller documentation and ONTAP documentation.

  • You must have the applicable licenses, network and configuration information, and cables.

  • You must have the completed cabling worksheets.

Note In addition to cabling graphics, this guide does provide sample worksheets with recommended port assignments and blank worksheets that you can use to set up your network.
For more information, refer to the Hardware Universe.
About this task

All Cisco shared switches arrive with the standard Cisco factory-default configuration. These switches also have the current version of the NX-OS software but do not have the RCFs loaded.

Important You must download the applicable NetApp RCFs from the NetApp Support Site for the switches that you receive.


  1. Rack the switches, controllers and NS224 NVMe storage shelves. See the
    Installing a Cisco Nexus 9336C-FX2 cluster switch and pass-through panel in a NetApp cabinet guide for instructions to install the switch in a NetApp cabinet.

  2. Power on the switches, controllers and NS224 NVMe storage shelves.

  3. Perform an initial configuration of the switches based on information provided in Required configuration information.

  4. Verify the configuration choices you made in the display that appears at the end of the setup, and make sure that you save the configuration.

  5. Check the software version on the switches, and if necessary, download the NetApp-supported version of the software to the switches.

    If you download the NetApp-supported version of the software, then you must also download the NetApp Network Switch Reference Configuration File and merge it with the configuration you saved in Step 3. You can download the file and the instructions from the Cisco Ethernet Switches page.
    If you have your own switches, refer to the Cisco site.

Required configuration information

For configuration, you need the appropriate number and type of cables and cable connectors for your switches. Depending on the type of switch you are initially configuring, you need to connect to the switch console port with the included console cable; you also need to provide specific network information.

Required network information for all switches

  • You need the following network information for all switch configurations:

    • IP subnet for management network traffic

    • Host names and IP addresses for each of the storage system controllers and all applicable switches

    • Most storage system controllers are managed through the e0M interface by connecting to the Ethernet service port (wrench icon). On AFF A800 and AFF A700s systems, the e0M interface uses a dedicated Ethernet port.

  • Refer to the Hardware Universe for the latest information.

Required network information for Cisco Nexus 9336C-FX2 switches

For the Cisco Nexus 9336C-FX2 switch, you need to provide applicable responses to the following initial setup questions when you first boot the switch. Your site’s security policy defines the responses and services to enable:

  1. Abort Auto Provisioning and continue with normal setup? (yes/no)

    Respond with yes. The default is no.

  2. Do you want to enforce secure password standard? (yes/no)

    Respond with yes. The default is yes.

  3. Enter the password for admin.

    The default password is admin; you must create a new, strong password.

    A weak password can be rejected.

  4. Would you like to enter the basic configuration dialog? (yes/no)

    Respond with yes at the initial configuration of the switch.

  5. Create another login account? (yes/no)

    Your answer depends on your site’s policies on alternate administrators. The default is no.

  6. Configure read-only SNMP community string? (yes/no)

    Respond with no. The default is no.

  7. Configure read-write SNMP community string? (yes/no)

    Respond with no. The default is no.

  8. Enter the switch name.

    The switch name is limited to 63 alphanumeric characters.

  9. Continue with out-of-band (mgmt0) management configuration? (yes/no)

    Respond with yes (the default) at that prompt. At the mgmt0 IPv4 address: prompt, enter your IP address: ip_address

  10. Configure the default-gateway? (yes/no)

    Respond with yes. At the IPv4 address of the default-gateway: prompt, enter your default_gateway.

  11. Configure advanced IP options? (yes/no)

    Respond with no. The default is no.

  12. Enable the telnet service? (yes/no)

    Respond with no. The default is no.

  13. Enable SSH service? (yes/no)

    Respond with yes. The default is yes.

Note SSH is recommended when using Cluster Switch Health Monitor (CSHM) for its log collection features. SSHv2 is also recommended for enhanced security.
  1. Enter the type of SSH key you want to generate (dsa/rsa/rsa1). The default is rsa.

  2. Enter the number of key bits (1024- 2048).

  3. Configure the NTP server? (yes/no)

    Respond with no. The default is no.

  4. Configure default interface layer (L3/L2):

    Respond with L2. The default is L2.

  5. Configure default switch port interface state (shut/noshut):

    Respond with noshut. The default is noshut.

  6. Configure CoPP system profile (strict/moderate/lenient/dense):

    Respond with strict. The default is strict.

  7. Would you like to edit the configuration? (yes/no)

    You should see the new configuration at this point. Review and make any necessary changes to the configuration you just entered. Respond with no at the prompt if you are satisfied with the configuration. Respond with yes if you want to edit your configuration settings.

  8. Use this configuration and save it? (yes/no)

    Respond with yes to save the configuration. This automatically updates the kickstart and system images.

    Note If you do not save the configuration at this stage, none of the changes will be in effect the next time you reboot the switch.

For more information about the initial configuration of your switch, see the following guide: Cisco Nexus 9336C-FX2 Installation and Upgrade Guide.
