  • 1.  QFX3500 - Virtual Chassis unsupported?

    Posted 05-31-2022 09:53

    Hi everyone,

    First time poster here.

    I recently purchased two refurbished QFX3500s with the purpose of implementing HA switching.

    After I configured my primary switch with the below commands, I noticed that when I `show config` it says the virtual-chassis code block is not supported.

    ```

    ##

    ## Warning: configuration block ignored: unsupported platform (qfx3500s)
    ##
    virtual-chassis {
        preprovisioned;
        no-split-detection;                
        member 0 {
            mastership-priority 255;
            role routing-engine;
            serial-number XXXXX;
        }
        member 1 {
            mastership-priority 255;
            role routing-engine;
            serial-number XXXXX;
        }

    }

    ```

    From everything I've seen, two QFX3500s are a supported virtual-chassis configuration Understanding QFX Series Virtual Chassis

    I couldn't see any licencing requirements for the QFX3500 for basic virtual-chassis configuration Licenses for QFX Series

    Both swtiches are configured as standalone switches, in accordance with Configuring a QFX3500 Device as a Standalone Switch

    Any suggesstions or ideas as to why my primary switch says the block is not confiured are welcome.

    The secondary/alternate switch just has the standalone configuration applied to it, not VC configuration.

    "For QFX3500 or QFX3600 switches in a Virtual Chassis, you must download the Junos OS image that supports Virtual Chassis-an image that includes "jinstall-qfx-3-" in the filename when the Junos OS image is downloaded from the Software Center. QFX3500 and QFX3600 switches that are node devices in a QFabric system cannot be part of a Virtual Chassis."

    Hi smicker,

    I honestly don't know how I missed that one line in the documentation, but that seems to be the issue.
    If the image didn't support VC, should the commit check still pass?

    |'m downloading a much newer OS version now and it has that prefix, so will test shortly.

    Kind regards,
    Alex​
