Hi Tanay,

Based on the details of the ConnectX-6 from one of the FABRIC VMs and the DPDK documentation you shared (DPDK MLX5 Guide), it appears that the ConnectX-6 available in FABRIC is not supported. We are currently working on integrating new BlueField DPUs, which may provide a suitable solution.


[root@Node2 ~]# lspci | grep X-6
06:00.0 Ethernet controller: Mellanox Technologies MT28908 Family [ConnectX-6]
07:00.0 Ethernet controller: Mellanox Technologies MT28908 Family [ConnectX-6]
[root@Node2 ~]# mstconfig -d 06:00.0 query
Device #1:

Device type: ConnectX6
Name: MCX653106A-ECA_Ax
Description: ConnectX-6 VPI adapter card; H100Gb/s (HDR100; EDR IB and 100GbE); dual-port QSFP56; PCIe3.0 x16; tall bracket; ROHS R6
Device: 06:00.0


Thanks,

Hi Rajiv,

L2STS links should work with SharedNICs. Could you please share your slice details where this is not working?

Thanks,

Komal

I also just noticed the attached screenshot. The Permission error is related to SmartNIC usage. To use SmartNICs for your project, you still need the Component.SmartNIC permission.

Thanks,
Komal

Hi Vaneshi,

The fix for this was deployed. I will check this again if you are still noticing this error.

Please note the pre-requisite for this is that both the listener and the monitored node are in the same slice.

Thanks,

Komal

Hi Jiri,

Could you please share the Fingerprint for your old SSH key which is not expired but not working now?

Thanks,

Your slice is already in a Dead state, meaning all associated resources have been released.

Please try creating your slice again and let us know if the issue persists. To help us investigate potential problems before expiration, consider extending your slice’s lifetime if you encounter this issue again.

Subject: Network Configuration Issue on Slice VMs

Hi Prateek,

I checked your Slice. Could you share the VMs and sites where the network configuration was lost?

The WASH and STAR site workers were rebooted due to another issue, which may have caused this disruption. Please note that, in the current version, fablib configures interfaces using ip commands, which are not persistent across reboots.

We are working on making this configuration reboot persistent. In the meantime, please consider using NetworkManager or netplan to configure the interfaces in a way that persists after a reboot.

Additionally, we are addressing the underlying issue that required the worker node reboots.

Apologies for the inconvenience, and thank you for your patience!

Best,
Komal

Hi Nirmala,

Could you please share your slice id?

Thanks,
Komal

Hi Yuanjun,

We had leaked config on the switch which has been cleared by help from Network Team. Could you please try your slice again? Please let us know if you still see the issue.

Thanks,
Komal

User has confirmed in another post that this issue has been resolved.

SSH Connection Error: ChannelException(2, ‘Connect failed’)

[Komal Thareja]

User has confirmed that this is no longer an issue.


HI, Komal

The problem has been solved. I believe we do not need the meeting today.

Thank you so much for your help!

Best Regards,
Yuanjun Dai

Subject: API Behavior Verification

Hi Yuanjun,

I have verified this, and the API is functioning as intended.

fablib.list_sites() retrieves resource information from the testbed. Once fetched, users can display data for a specific site using fablib.show_site(). Please note that fablib.show_site() only presents site information that was previously retrieved via fablib.list_sites().

To refresh the resource information, you need to call fablib.list_sites(update=True), followed by fablib.show_site().

Please check this in your code, and let us know if you continue to experience any issues.

Thanks,
Komal

Hi Yuanjun,

Both the issues with upload_file and this point to SSH access to the VMs. It could be because of the expired bastion keys or a configuration issue.
Is it possible for a quick zoom meeting to resolve this? Please let me know if that works.

Thanks,
Komal

Hi Ilya,

I checked the host and see a similar output. Will check with Mert regarding the reboot.

Hi Ilya,

Hussam helped recover the WASH worker. Could you please try your slice again on WASH?

Thanks,

Komal
