Problem Adding >30 interfaces to vJunos-switch image

Before posting something, READ the changelog, WATCH the videos, howto and provide following:
Your install is: Bare metal, ESXi, what CPU model, RAM, HD, what EVE version you have, output of the uname -a and any other info that might help us faster.

Problem Adding >30 interfaces to vJunos-switch image

Post by dark_15 » Thu Apr 27, 2023 2:37 am

Hi All! Let's get the details out of the way:

Your install is: Bare metal: Intel BOXNUC8I3BEH3 NUC
CPU model: Intel Core i3 (8th Gen) 8109U/ 3-3.6GHz
RAM: 32GB
HD: 500GB SSD
Eve Version: 5.0.1-19-Community

Code: Select all

root@eve:~# uname -a
Linux eve 5.17.8-eve-ng-uksm-wg+ #1 SMP PREEMPT Mon May 16 10:08:59 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
I am having an issue where I cannot turn up more than 30 interfaces on a Eve-NG template I've written up.

When I try to run this image with more than 27 interfaces (two are reserved for fxp and internally), the vJunos-switch image will not boot. I know that up to 96 interfaces are supported, and I see the interfaces being created on the eve system when I start:

Code: Select all

root@eve:~# ifconfig| grep vun | wc -l
98
But at this point I need to restart the system in order to remove those interfaces properly so I can boot any further KVM images. Once I reboot and set the number of interfaces to 27, the image boots without an issue.

I did capture a screenshot (attached) with the error message I see on the console. Is there something I'm missing which prevents me from creating the maximum documented interfaces?

Re: Problem Adding >30 interfaces to vJunos-switch image

Post by Uldis (UD) » Thu Apr 27, 2023 6:45 am

Juniper claimed themselves, only 11 interfaces are supported for vEX 23.1

And on this CPU i3, it is wonder if you could even start this vEX

Re: Problem Adding >30 interfaces to vJunos-switch image

Post by dark_15 » Thu Apr 27, 2023 12:26 pm

I've been able to get 25 interfaces connected easily. And boot up 4 vJunos-switch appliances without a problem at 25 interfaces, and forward traffic on all of them. But it really looks like the wrapper script is truncating commands somehow or breaking something.
Juniper claimed themselves, only 11 interfaces are supported for vEX 23.1
They claim 96 interfaces, but have an open PR (PR1720270) that limits interface configuration to 64 interfaces. You can adjust the number of interfaces on the PIC using the command set chassis fpc 0 pic 0 number-of-ports <n> <- the default is 10.

But I can't even get 30 interfaces to boot. 29 interfaces works; 30 does not. I should note this is the interface count in Eve-NG; which translates out to 27 configurable interfaces inside vJunos-switch.

The CPU is i3, but it's Coffee Lake and has VT-x support. It's nice to have a bare metal Eve-NG lab that fits in the palm of my hand and is near silent.

Are there better diagnostics/logs I can run in order to see why the qemu-ifdown command is failing?

You WAS able...
but current Juniper EX supports only 11, thats it
it is official announce from from Juniper...

read here

I was happey with pre release, but now it is what it is

This is an incorrect statement, and I would ask that you please provide a link to where the 11 interface limitation is documented.

Juniper has made no such announcement on the interface limitations outside of the aforementioned PR where 96 interfaces can be added to the pic, but only 64 interfaces can be configured. The release notes show no such limitations. Here is my current lab setup:
Screenshot 2023-04-28 at 16.25.26.png
By default the image will only show 11 interfaces, including fxp0 (and em1, IIRC):

You can easily change this by adjusting the chassis FPC/PIC settings:

Code: Select all


[edit]
root@vJunos-switch-1# set chassis fpc 0 pic 0 number-of-ports ?     
Possible completions:
  <number-of-ports>    Number of physical ports to enable on PIC (1..96)

root@vJunos-switch-1# set chassis fpc 0 pic 0 number-of-ports 26 

[edit]
root@vJunos-switch-1# commit

Now when I check the interface statuses you can see the interfaces and I can configure them without issue:

Code: Select all

I am able to pass traffic on the interfaces - including those beyond ge-0/0/9 - without a problem. I just configured BGP on those interfaces which establish just fine:

Configuration aside, when I try to start the VM with 30+ interfaces the VM fails to boot, and I end up with a mess of vun interfaces that don't clear out until I reboot the system running eve-ng. and the the error messages on the console in the attached picture clearly show that something is borked with qemu/unl_wrapper, and right at interface #29:

I can also reproduce this behaviour on other VMs, such as the vMX-VFP, which is supposed to support 96 interfaces as well; when I add 30 interfaces or more the VM will not start, and leaves a mess of vun interfaces:

I'm fairly confident the unl_wrapper is truncating the interface config, based on the logs I've gleaned so far. What other logs/details can I look at to confirm my suspicions?

Re: Problem Adding >30 interfaces to vJunos-switch image

https://www.eve-ng.net/index.php/docume ... ex-switch/

All works, 11 interfaces VEX

previous image vEX 21.1R1 which I got from Juniper was ok with 24 NICs

For vMX is hint
Edit vMX templates and set VFP and VCP ethernet interface type to virtio
Edit VCP template to set int qnty to 25

Code: Select all

[edit]
root@vmx# set chassis fpc 0 pic 0 number-of-ports 23
65 NICs also works on cisco Nexus 9000v

just a question why for labbing need 100 NICs???

Solved, Attached updated template
and after in edit mode issue:

Code: Select all

set chassis fpc 0 pic 0 number-of-ports 64
On Pic 64 interfaces Juniper vEX switch
