Could you please try this with Beyond Bleeding Edge Container? I wasn’t able to reproduce this issue there. Trying it with 1.8 Stable container now.

Thanks,

Hey Kriti,

Could you please share which JH container were you using when you noticed this issue?

Thanks,

Also, could you please share which JH container are you using?

Hi,

Both your slices  are in Stable State. It seems like a bug in fablib or a race condition which is causing fablib to think the slice is still Configuring.

As a workaround, could you please do the following?

I am trying to reproduce this at my end and would work to fix this. Apologies for the inconvenience!


slice=fablib.get_slice(slice_name)
slice.post_boot_config()
slice.list_nodes();
slice.list_interfaces();

Hi Raghav,

Please set up your JH environment by running the notebook: jupyter-examples-rel1.8.1/configure_and_validate/configure_and_validate.ipynb

This shall setup all the required configuration files and SSH keys. Please try the Wide Area Link notebook or Hello Fabric after that to ensure your configuration works. Please let us know if you run into issues.

Thanks,

Komal

Issue resolved over zoom meeting, the issue was the token.

Token file only had id_token instead of the entire token contents. Downloading the token file and using that resolved the issue.

Please let us know if you run into any other issues. I have taken a note to return a more user friendly error. We will address this in the next release.

Thanks,

Komal

Reached out to Vaneshi via email to request a meeting to work to resolve this!

Hi Raghav,

The data plane interfaces on your VMs connected via L2STS do not have IP addresses configured.

The enp3s0 interface on your VMs is designated as the management interface and should be used solely for SSH access. For your experiment, please use the data plane interfaces, which are enp7s0 on both VMs.

I recommend exploring the JH example—Wide Area Link (Layer 2)—using manual, auto, or user-defined configurations, as it demonstrates how IP addresses should be set up.  Please, let us know if you encounter any further issues.

Hi Kriti,

I think the attachment got lost. Could you please email it to me directly at kthare10@renci.org?

Hi Kriti,

I can verify that your slice is StableOK. Please check the portal to verify that.

This looks like a bug, where fablib may be reflecting the stale state. If possible, could you please share your notebook, so I can try to reproduce this on my end and fix the bug? Appreciate your help with this.

Hi Kriti,

Could you please share your slice id?

Hi Vaneshi,

I am unable to reproduce this with any of the JH containers. I do notice a small error in the API posted above. quiet parameter is a boolean.

Could you please check the following?

• You have a valid token in ~/.tokens.json
• Try the snippet below


from fabrictestbed_extensions.fablib.fablib import FablibManager as fablib_manager
fablib = fablib_manager()
cx5_column_name = 'nic_connectx_5_available'
cx6_column_name = 'nic_connectx_6_available'
sites_connectx_json = fablib.list_sites(
output="json",
quiet=True,
filter_function=lambda x: x[cx6_column_name] > 0 or x[cx5_column_name] > 0,
latlon=False,
)
print(sites_connectx_json)


Please let me know if you still run into errors.

Thanks,

Komal

Hi Raghav,

Could you please check if the interfaces on the VMs have the IP addresses configured?

Also, please share the Slice ID for your slice. This will help us take a look at it as well.

Thanks,

Komal

Hi Ilya,

Thanks for the kind words—we appreciate the feedback!

To ensure the network interfaces retain their configuration after rebooting, please use the following code to reconfigure all nodes in the slice:

for n in slice.get_nodes():  
    n.config()

This will restore the network configurations.

Regarding DPUs, we’re currently exploring BlueField 2 DPUs and targeting summer for initial support, with more details coming soon. Stay tuned for updates!

Please let us know if you run into any other issues.

Best Regards,

Komal

Hi Sourya,

It appears that your slice utilizes a Port Mirror service, which may not yet be supported by the Slice Viewer. We will check with Yaxue, who works on the Portal, to confirm this. We are working on adding support for this feature in the next release. Apologies for any inconvenience.

Thanks,

Komal
