Options to trigger remote reset of Arria 10 using "magic packet" approach?

Hi, We have a rare failure scenario on our deployed Arria 10 based devices whereby we see loss of connectivity back to our remote server, resulting in an inabiity to establish a 2-way SSH connectiv...

Hi Munster-shug


Sorry for the late reply as there was a public holiday here.


There is no built in capability for the scenario that you are experiencing.


One way that I could think of is creating a script running in the back ground under the linux systemd which will be checking the connection to your remote server.

To further understand your problem, is the connection to your remote server intermittent lost or is it permanent?

Is the connection lost only to your remote server or is it able to still ping external sites?


Regards

Jingyang, Teh

    Thanks Teh,

    ACtually it is a little bit of a strange situation....

    Remote device is connected via fibre.

    We are normally able to SSH into the device, however for some unknown reason there are intermittent failures into some devices (frequency is highly varied, ranging from 4-14 hours) whereby the SSH connectivity is lost.

    Ping to remote device is not replied.

    ARP commands sent from host server via fibre to our remote device are not responded to (wireshark logs).

    Meanwhile the remote device continues to stream packets back up the uplink fibre.

    The SFP transceievers are reporting link is up in both directions.

    We suspect the MAC scheduler is frozen..... ......and hence we are looking for way to reset either the mac scheduler or the FPGA

    WE are open to any other suggestions

    Thanks
