I configured the IP address as it was before it crashed but cannot ping the other nodes using the dataplane. Is there something else I should do?

Thank you very much Charles.

Found out the config file path is actually /opt/fabric_prometheus/prometheus/config/prometheus_config.yml

Hello Robin,

I am not very familiar with SR but I notice that you did not reserve network resources no connect the nodes with links. I never had to perform iperf using management IPs on this testbed so I am not sure how it should behave. Sorry I have to been more helpful.

Hi Robin,

Could you share your notebook(s) here. It helps to replicate the issue and hopefully resolve and share a resolution.

Hi Jiri,

Your interfaces appear to be down from the images you shared.

You can bring them up with these commands before trying to “download the file to the client”:

stdout, stderr = server.execute(f’sudo ip link set dev {server_iface.get_os_interface()} up’)
stdout, stderr = client.execute(f’sudo ip link set dev {client_iface.get_os_interface()} up’)

I tried again and it creates the slice but sets the network of node interfaces to “None” for some reason.

For reference: content of the requirement.txt file in both the version (1.5.4) and the fabric_config folder was cleared out and saved. Then “File” >> “Hub control panel” >> “Stop my server”….and, “Start my server”. Error goes away after.

What can I do differently, please. Does this have to do with creating the OpenVSwitch after the faces and routes were created?

Hi yoursunny,

Kindly find the notebook here

See also the terminal commands to setup OVSwitch on the “switch” below:

sudo apt-get -y update && sudo apt-get -y upgrade

sudo apt-get -y install openvswitch-switch openvswitch-common

sudo ovs-vsctl add-br br0

sudo ovs-vsctl add-port br0 ens7

sudo ovs-vsctl add-port br0 ens9

sudo ifconfig ens7 0

sudo ifconfig ens9 0

sudo ifconfig br0 up

Regards,

Acheme
