  • 1.  Unable to load junos on vqfx-pfe

    Posted 01-15-2020 02:03

    Good morning,


    I am running the the virtual appliance of the QFX10000 Switch, the name of the image is cosim-18.4R1.8_20180212.qcow2.


    I am able to login into the Unix shell by using username = root, password = no, but I am unable to start the junos CLI.


    I read that for starting junos CLI from the Unix shell typing cli is enough, but it does not work with this image.


    I am attaching a screenshot of the message.


    Thanks in advance.

    I believe you are in the host shell of the vqfx and not the junos shell. 

    The cli will work on the junos (unix) shell however it would not work on the host shell.

    Also cosim image is the pfe image what is the junos image that you are using ?

    Hi gmarciales,


    To make the virtual appliance work full blown, you need an RE and PFE.  The cosim image is just the PFE part of it, you should also be running "jinstall-vqfx-10-f-18.4R1.8.qcow2" and ensure there is a dedicated virtual connection (em1 typically) between the RE and PFE.  On PFE you can check if the interface to RE is up (typically eth1).  Once the RE to PFE connection is up, we can just login to the RE to get to Junos CLI, you won't need to login to the PFE.


    Check this for some basic troubleshooting for this RE/PFE connection:



    Hope this helps.
