CSR1000v running on 17.2.1r deployed on MS Azure VM.
lost access to it suddenly, tunnel re down. NO CLI into the device.
Was inaccessible from the serial console as well
We saw several “gibberish” logs on the screen. Apart from that, we had nothing.
reloaded the VM instance and the CSR came back up.
The only relevant logs that are pointing us to Mellanox is below :
mlx5_core b7dd:00:02.0 eth0: Error cqe on cqn 0x41c, ci 0x0, sqn 0x50d, syndrome 0x1, vendor syndrome 0x68.
If it’s a bug, what needs to be done by Microsoft/Cisco to mitigate the issue.
