Hello,

Your slice is set to close by November 20th and is currently in the StableOK state. If needed, you can request to renew your project to continue using this slice. Alternatively, I can delete the slice if that is your intention.

Hi Luca,

Not much luck with it! I can reproduce what you are observing on CLEM but haven’t found a resolution yet. However, I did notice that when I start pktgen and all the containers are up and running. I keep noticing following error in the container sn-stack-ubuntu-smartnic-cfg-1

Probe reports few drops as soon as I start pktgen but after that it just keeps reporting all 0s.

Hey Luca,

I was looking at your slice on SRI and noticed two containers sn-stack-ubuntu-smartnic-cfg-1 and sn-stack-ubuntu-smartnic-p4-1 are restarting. I suspect that could be the reason for traffic issue.

Your DALL slice is expired so I could not check there.

The logs in both of them suggest FPGA is not ready.

Correction, FIU has been flashed with bit file compatible with XDMA shell so may not work with ESNet workflow.

[Komal Thareja]

Thank you Luca for sharing the slice information. I will investigate this further and keep you posted.

Could you please extend the slices for atleast upto a week so they don’t expire?

As a first check, FPGAs on the GATECG, FIU, SRI seem to be flashed with a bitfile compatible with ESNet workflow. I will check about KANS and LOSA and confirm.

Thanks,

Komal

Hi Luca,

Could you share the sites where you encountered this issue? I tried CLEM, and it worked fine.

As mentioned here, we collaborate with the experimenter to flash the FPGA with the initial bitstream. We’d like to rule out whether a different bitstream (other than ESnet) was used for flashing the FPGA at the sites where you experienced the problem. Also, if you have the slice up where you see the error, please share your slice ID with us!

Thanks,
Komal

Hi Kriti,

It appears that there may be a configuration issue with your experiment. I recommend checking your settings. Based on your slice, there’s a Layer 2 network established between ipnode-1 (192.168.14.1) and n6 (192.168.14.254).

I can confirm that pinging from ipnode-1 to n6 is successful, which indicates that the underlying Layer 2 network is functioning properly. While you do have a route on ipnode-1 to direct traffic through n6, it seems that the subnet you’re trying to access is not reachable from n6. This issue seems to be specific to your experiment’s configuration, so you may need to troubleshoot on your end.

Hi Kriti,

I created a slice on MASS for a Layer2 Network as well as Layer3 network. Both slices were able to pass traffic.

This may be something specific to your slice or configuration. Please share your slice id. We can help to take a look but would also recommend checking configuration on your side as well.

Thank you for letting us know about the portal. We will work on addressing that as well.

Thanks,

Komal

Hi Kriti,

Could you please open the Calendar by clicking on the small square shown next to Lease End at to choose the timestamp and then click on Extend?

Also, you can extend your slice by following methods as well:

• Notebook accessible from Start_here -> Extend Slice Reservation
• slice-commander command line utility available in JH container


fabric@fall:system-29%$ slice-commander
Usage: renew <days> [SliceName1, SliceName2, ...]


Please let us know if you run into issues or errors.

Thanks,

Komal

[Komal Thareja]

The maintenance is complete and the new model has been deployed.

Hi Prateek,

It seems that the teaching materials are somewhat outdated. Users no longer need to manually complete the steps under “Configure your Jupyter environment.” Instead, they can simply run the latest jupyter-examples-rel1.7.*/configure_and_validate.ipynb notebook to set up their Jupyter Hub environment.

If you have any questions or encounter any issues, don’t hesitate to reach out.

Thanks,
Komal

[Komal Thareja]

I also wanted to mention another option you can utilize: TailScale, which doesn’t require Ext services. You might find the Jupyter example helpful—check it out here.

Thanks,
Komal

Hi Sourya,

While your request is being reviewed, please consider trying the workaround suggested by @yoursunny here: https://learn.fabric-testbed.net/forums/topic/reaching-the-internet-from-a-fabnet-node/#post-7605

Thanks,
Komal
