Hi Tanay,

We’re in the process of deploying them and are targeting DPU availability at KNIT11 around October 13–14.

Best.

Hi Nishanth,

Could you please try again? It should work now, freebsd fix introduced this check, i have disabled it now.

Hi,

Fix for this issue has been deployed on production. Please try creating a slice and let us know if you run into any issues.

Hi Tejas,

You can use FABRIC’s Layer 3 FabNetv4 or FabNetv6 Network Service to establish connectivity between slices.

Any VM connected to FabNetv* in one slice can communicate with a VM connected to FabNetv* in another slice, provided the routes are configured correctly. You just need to add the following routes:

ip route add 10.128.0.0/10 via <fabnetv4_gateway>
ip -6 route add 2602:FCFB:00::/40 via <fabnetv6_gateway>

You may also find this example artifact helpful, as it demonstrates inter-slice connectivity using FabNetv4.

Best,

Thank you for sharing this, Nishant and YoursSunny.

I was able to reproduce the issue. On IPv4 sites, user SSH keys are not being injected, and on IPv6, SSH connections are failing completely. We’ll work on addressing this and will let you know once the fix has been deployed. Apologies for the inconvenience in the meantime.

Best,

Hi Dagim,

Thank you for sharing this observation. Could you update the instantiation of the fablib object in the first cell to the following and then try running the notebook again?

fablib = fablib_manager(project_id=project_id, validate_config=False)

Thanks,
Komal

Hi Zhihe,

This was a bug, a fix has been deployed on the default container. Could you please try running this notebook again?

Thanks,

Komal

[Komal Thareja]

Yes please Nirmala – Just keep the following in that file:

This should allow you to delete older examples.

{
"examples": [
{
"url": "default",
"location": "/home/fabric/work"
}
]
}

Best,

Hi Philip,

We discussed this internally, and the minimum supported bandwidth value is 1 Gbps. At this time, we don’t have plans to provide more fine-grained options. If you need to simulate lower bandwidth, we recommend using tools such as tc.

Hi Jacob,

Thank you for sharing the details. I discussed the energy consumption measurement topic with the team earlier today.

As mentioned before, we do not currently support energy consumption measurements on the VMs. The network team also confirmed that such measurement capabilities are not available on the network devices.

For identifying the geolocation of hops, we recommend using the L2PTP (Layer 2 Point-to-Point) network, where the user explicitly defines the network path by specifying the SITEs for each hop. You can then use fablib.list_sites() to obtain the geo-coordinates.

Please refer to this artifact for guidance on setting up an L2PTP slice:
https://artifacts.fabric-testbed.net/artifacts/7e439627-96be-45e0-ab67-50bb607f06e4

 

Also, regarding the renewal request, I see that it was submitted yesterday. Michael will follow up on that through the ticket.

Best,

Komal

Hi Nirmala,

You don’t need to keep the example notebooks, so please go ahead and remove them.

Could you also take a look at the contents of /home/fabric/fabric_config/fabric_config.json? I suspect there may be multiple entries in that file. If so, please delete it as well—this should prevent the older examples from being retained when you log in again.

Best,

Komal

Hi Jacob,

At the moment, energy consumption measurements are not passed into the VMs. I’ll bring this up in our planning meeting so it can be considered for inclusion in a future release.

For location information, we currently expose the geo-coordinates for all FABRIC sites, which you can retrieve using fablib.list_sites(). One possible approach to determine the location of hops is to map IPs → Sites → Locations.

Could you share your slice ID or specify the type of network service you’re using for your WAN experiment?

Best,

Komal

Hi Rasman,

The dataplane was down at MASS. The link has been restored, could you please try running the iPerf3 cells again from the notebook. Apologies for the inconvenience.

Thanks,

Komal

[Komal Thareja]

Hi Rasman,

I was able to run iperf3 optimized notebook without issues. I am unable to access your notebook. It says Page Not Found.

Could you please share your slice ID?

Thanks,

Komal
