Dell SmartFabric OS10 Installation, Upgrade, and Downgrade Guide


Install OS10 license

If OS10 is factory-loaded on your switch, you do not need to install an OS10 license as it is pre-loaded with a perpetual license. If you download OS10 on a trial basis, OS10 comes with a 120-day trial license. ONIE installation on a factory-loaded Dell switch wipes out the license partition. Hence, the switch on reload comes up with a default 120 day trial license. Purchase and install a perpetual license after the trial period expires.To continue with uninterrupted use, purchase and install a perpetual license to avoid the OS10 device rebooting every 72 hours after 120 days.

After you install OS10 and log in, install the perpetual license to run OS10 Enterprise Edition beyond the trial period. The OS10 license is installed in the /mnt/license directory.

  1. Download the file from DDL as described in Download OS10 image.
  2. Open the zip file and locate the license file in the Dell folder. Copy the license file to a local or remote workstation.
  3. Install the license file from the workstation in EXEC mode.
    license install {ftp: | http: | localfs: | scp: | sftp: | tftp: | usb:} filepath/filename
    • ftp://userid:passwd@hostip/filepath—Copy from a remote FTP server.
    • http://hostip/filepath—Copy from a remote HTTP server.
    • http://hostip—Send a request to a remote HTTP server.
    • localfs://filepath—Install from a local file directory.
    • scp://userid:passwd@hostip/filepath —Copy from a remote SCP server.
    • sftp://userid:passwd@hostip/filepath—Copy from a remote SFTP server.
    • tftp://hostip/filepath —Copy from a remote TFTP server.
    • usb://filepath—Install from a file directory on a storage device connected to the USB storage port on the switch.
    • filepath/filename—Enter the directory path where the license file is stored.
NOTE When installing a license through a VRF instance, OS10 supports only some file transfer methods. The following table details the file transfer methods supported in default, management, and non-default VRF instances.

    OS10# copy scp://admin:admin@ home://7B900Q2-NOSEnterprise-License.XML
  2. (optional) Check the status of the file copy using the show copy-file status command.

    File Transfer State:   idle
    State Detail:          idle
    Task Start:            2019-02-15T00:46:35Z

    Transfer Progress:     100 %
    Transfer Bytes:        3795 bytes
    File Size:             3795 bytes
    Transfer Rate:         8 kbps
  3. Verify that the license is present in the home directory of your system.
    OS10# dir home

    --------------------- ------------ -----------------------
    2019-02-15T00:47:25Z 3795 0A900Q2-NOSEnterprise-License.XML 
  4. Enter the license install command with the path to the home directory location where the license was downloaded in step 1.
    OS10# license install localfs://home/admin/0A900Q2-NOSEnterprise-License.XML
    License installation success.

Install license using management VRF

OS10(config)# ip vrf management
OS10(conf-vrf)# interface management

Troubleshoot license installation failure

An error message displays if the installation fails.

License installation failed
  1. Verify the installation path to the local or remote license location.
  2. Check the log of the remote server to find out why the FTP or TFTP file transfer failed.
  3. Ping the remote server from the switch—use the ping and traceroute commands to test network connectivity. Check the following if the ping fails:
    • If the remote server is reachable through the management route, check if the management route is configured correctly.
    • If the remote server is reachable through a front-panel port, check if the static or dynamic route is present.
    • If the ping is successful and the FTP or TFTP log on to a remote server does not register a response, check if there is a firewall in the transfer path that is blocking the transfer protocol.
  4. Install the server with the license file on the same subnet as the switch.
  5. Check if the server is up and running.
