Release Version Feature Description

Nexus Dashboard 4.2.1

There were no major changes from the previous release.

Working with tech support

Tech support enables you to collect logs and activities in the system for further troubleshooting by Cisco TAC. Cisco Nexus Dashboard provides tech support collection and gives ability to download tech support for the whole cluster. Tech support files are hosted on the Cisco Nexus Dashboard and can be downloaded at any time.

These are the maximum number of tech supports that can be generated:

  • 10 for a physical applicance, and

  • 3 for virtual appliance.

To collect Tech Support information:

  1. Collect Tech Support.

    1. From the main navigation menu, select Admin > Tech support.

    2. In the main pane, click Collect Tech Support Files.

  2. In the Collect Tech Support window that opens, provide a name.

  3. (Optional) Check the box next to the Tech Support for the last 24 hours field.

  4. Click Collect.

    After you begin the tech support collection, you can see the progress in the same screen.

    If for any reason the tech support collection process fails, you can also obtain the same information by logging into each node as the rescue-user and running one of the acs techsupport collect commands. For more information about specific techsupport collect command options, see Useful Commands.

  5. Download the tech support archive.

    After the collection is finished, you can download the archive by clicking the ellipsis ( …​ ) on an entry and choosing Download all. You can also download the archive by clicking on the entry in the Nodes column and clicking Download all in the drawer that appears.

If you want to delete an existing tech support package, click the ellipsis ( …​ ) on an entry and choose Delete tech support. You can also delete a tech support package by clicking the box next to an entry and clicking Delete Selected Tech Support.
