    Hello,

    I'm running VMX on my Ubuntu(Install Ubuntu on EXSI 5.5). VCP et VFP are running (cf below),but can't find interface ge port ,did any help to check it.

    Thanks

    Try this:

     

    "set chassis fpc 0 lite-mode"

     

    If this works, problem is with Memory or/and CPU.

    Bingo!
    Changing FPC to lite-mode worked.
    I have raised memory to 16GB for vCP and 16GB for vFPC and FPC won't get online.
    Keeps show FPC as PRESENT and not online.
    Don't know what to do here...

    This solution worked for me.
    FPC and CP won't connect to each other if not using lite-mode.
    I've added 16gb and 16 procs on each and it still won't work.
    Don't really know how to run on performance-mode since it won't work. I guess there is a problem with this performance mode.
    Cheers.

    Hi,

     

    Are you able to ping the VFP from the VCP over the internal bridge (not management link)  please can you provide output showing this

     

    On 15.1 / 16.1 the command is

    ping 128.0.0.16 routing-instance __juniper_private1__

     

    Thanks

    Please can you confirm how much memory you have allocated to the VCP and VFP?

    Having exactly the same issue running under KVM (Linux kernel 4.4) running in lite mode, 1 vCPU allocated to vCP and 3 vCPU allocated to vFP with 2GB/8GB memory allocated respectively.

     

    Basic connectivity between them seems to be fine, the vCP and vFP just never connect. Physical host is a dual Xeon E5-2630v2 with 256GB memory, nothing else running on it. Problem only seems to have started after someone did an apt-get -y update && apt-get -y upgrade on the box.

    If you log in to the VFP console, what do you see in the crash logs (/var/crash) ?

     

    Also if you look in the VFP syslog file in /var/log/messages do you see the below?

    RPIO: Accepted connection from 128.0.0.1:50896 <-> vPFE:3000
    RPIO: Accepted connection from 128.0.0.1:56098 <-> vPFE:3000
    HOSTIF: Accepted connection

     

    Also note that JTAC will only support the following OS/Kernel versions for vMX

    Ubuntu 14.04 LTS (recommended host OS)
    Linux 3.13.0-32-generic

    QEMU-KVM 2.0.0+dfsg-2ubuntu1.11 or later

     

    Red Hat Enterprise Linux 7.2
    Linux 3.10.0-327.4.5 or later

    QEMU-KVM 1.5.3 or later

    Ok so have found the underlying issue, the vMX configuration has the following parameters in it;

     

    FORWARDING_PLANE:
    memory-mb : 8192
    vcpus : 3

     

    Yet it seems to only be booting with 1 vCPU;

     

    root@localhost:~# lscpu
    Architecture: x86_64
    CPU op-mode(s): 32-bit, 64-bit
    Byte Order: Little Endian
    CPU(s): 1

    On-line CPU(s) list: 0
    Thread(s) per core: 1
    Core(s) per socket: 1
    Socket(s): 1
    NUMA node(s): 1

     

    root@localhost:~# cat /var/log/messages | grep CPU

    Oct 26 15:49:22 localhost user.notice root: vFP Error! Insufficient number of CPUs 1

     

    Same issue present on an Ubuntu 14.04 LTS 3.13.0 kernel box running QEMU 2.6.0.

    I see a similar problem - although I am running directly on ESXi (using the OVAs supplied by Juniper). 

     

    My /var/log/messages | grep CPU also shows this message:

    vFP Error! Insufficient CPUs

     

    However, I have 7 cores assigned to it in ESXi (lscpu confirms this).. Not sure what the issue _really_ is, but I seem to have had more success moving the assigned RAM for the vFPC up to 16GB (it was at 8GB). This is all on a trial license, that could be something to do with it as well. 

     

    I first had an issue in that I could ping between the VCP and VFPC just fine, but I was always seeing FPC 0 as 'Absent' in 'show chassis fpc'. Now (having added double the RAM) - I can see my FPC 0 there, in 'Online   Testing' state.. ge-0/0/0 appears to be up, so I'll move on carefully from here.

     

    Thanks for the tips in this thread.

    Add vMX 60-days trial license and check. 



  • 15.  RE: vMX can't connect fpc,slot 0 Absent

    Posted 02-23-2018 06:31

    I have a similiar issue on vMX 14.1R1.10 .

     

    On my Fusion I can see PIC 0 being listed on show chassis fpc pic-status  and on show chassis hardware .

     

    Then exported the vMX vm with cli ovftool and imported into Cloudshare cloud provider, that pretty much is a huge ESX server.

     

    There I cannot see PIC 0 and no ge-* interfaces are present.

     

    There's no lite command available and vMX trial from Juniper site cannot be installed as being detected as invalid.

    Posted 10-26-2016 09:11

    If you may share /var/log on both vCP and vFP?



  • 17.  RE: vMX can't connect fpc,slot 0 Absent

    Posted 04-27-2019 01:12

    Trying to restart an old thread before starting a new one...

     

    Did you find a solution to this?  I have the same issue with a vMX running 17.4R3-S2.  The FPC shows as present but absent.  I can ping between the two VMs and I have tried to increase the RAM to 8G (doc say 2G is enough for lite-mode).  A have a vMX running on 15.1 with the same set up and that is working so not sure what else to try.

     

    <edit>

    In the log messages on the VCP I can see the following:

    Hi Paul,

     

    What is the ESXi version used?

     

    Could you please share "*.vmx" file for both vCP & vFP. [It will be under datastore folder of both VM's]

    Same issue , I have not see a resolution  , on 18.3  as in the JNCIE-ENT blueprint.
