Lab00

In this lab, we will set up a simple topology with containerlab. We will create gnmi-target-switch0 and gnmi-target-switch1 (servers with a gNMI-target, handled as switches) that we manage with the goSDN controller. Afterwards, we change the name of gnmi-target-switch0 to switch0.

Please note: You need to have the lab-vm or all the software in Prerequisites installed to run this lab.

The figure below shows what we want to set up using the goSDN-Controller, goSDN-CLI and gNMI:

Run the containerlab

Go to the directory of gosdn and use following command:

make containerlab-slim-start

Open a new terminal and start the CLI to talk to the controller (Do not close the previous terminal)

Build command prompt

make build
cd artifacts
./gosdnc prompt

Login into the controller with the credentials

login --controller 172.100.0.5:55055 --u admin --p <password>

To get the password go to the previous terminal and use the following commands

docker logs clab-gosdn_csbi_arista_base-gosdn

In the end of the script a 16 character alphanumeric password is generated like this: “Generated admin password: uyslboh15gjp9dne” (not the actual password, just an example)

Set-up the PND ID

pnd use (Choose ID from the displayed menu)

Set-up the switches

Switch0:

mne create --address 172.100.0.11:7030 --name switch0 --username admin --password admin --tls --plugin-id d1c269a2-6482-4010-b0d8-679dff73153b

Switch1:

mne create --address 172.100.0.12:7030 --name switch1 --username admin --password admin --tls --plugin-id d1c269a2-6482-4010-b0d8-679dff73153b

Check if the switches were created

mne list

In here, the UUID is also visible which we need for the next step:

Please note that the UUID may vary.

Set another hostname for Switch0

First, we want to see the current hostname:

mne path get <UUID> system/config/hostname

We get following output:

Now, we want to change the hostname gnmi-target-switch0 to switch0:

mne path set <UUID> system/config/hostname switch0

After changing the hostname, we have to commit our change. The change-id may vary too, so you can use the auto-completion tool of the cli or get all changes with following command:

change list

After getting the change-id, we will execute following command:

change commit <change-id>

Now we have to confirm the commit:

change confirm <change-id>

If we execute the get-command again, we can confirm that the change took place:

mne path get <UUID> system/config/hostname

Shut down the containerlab

Go to the directory of gosdn and use following command:

make containerlab-slim-stop
