SD-WAN Versa Collector Deployment and Configuration Guide

To perform SD-WAN collector installation process, you will need to SSH into your machines using non-root credentials for the user sevone. Before continuing, you will need to SSH into each machine that you plan to run SD-WAN collector on and change the default password for this user. This applies whether you are using a SD-WAN appliance or have deployed an .ova. You will need to do this for all nodes (control plane and all agent nodes). This is important for security reasons.

1. SSH into your SD-WAN collector machine and log in as sevone.
2. At the Password prompt, enter sevone.
3. Execute the following command:

   $ passwd
   

4. At the prompt New password, enter a new password for the sevone user.
5. At the prompt Retype new password, enter the new password again.
6. Repeat the steps above for each machine that you plan to run SD-WAN collector on.

Execute the following command to install sevone-cli using Command Line Interface.

$ sudo rpm -Uvh /opt/SevOne/upgrade/utilities/sevone-cli-*.rpm

As a security measure, fresh installations do not ship with pre-generated SSH keys. Execute the following command to generate unique SSH keys for your cluster.

$ sevone-cli cluster setup-keys

1. Please refer to SD-WAN Versa Collector Pre-Deployment Guide to deploy a single SD-WAN Versa node.
2. Using ssh, log into the SD-WAN Versa collector control plane node as sevone.

   $ ssh sevone@<SD-WAN collector 'control plane' node IP address or hostname>
   

   Example

   $ ssh sevone@10.128.10.69
   

3. Change the hostname. For details, please refer to SD-WAN Versa Collector Use-Cases Guide > section Use-Cases > subsection Change Hostname.
   Important: Please make sure to set the hostname for all k3s nodes in lowercase when deploying the collector.

1. For a multi-node setup, repeat the steps in SD-WAN Versa Collector Pre-Deployment Guide for each additional node in your cluster. Every SD-WAN collector node ships as a running single-node Kubernetes cluster.
2. Using ssh, log into each node and change the hostname. In order to create a multi-node cluster, you must designate one of the nodes to be your control plane node. For details on how to change the hostname, please refer to SD-WAN Versa Collector Use-Cases Guide > section Use-Cases > subsection Change Hostname.
   Important:

   • Please make sure to set the hostname for all k3s nodes in lowercase when deploying or upgrading the collector.
   • If you have created cluster or added agent nodes using the hostname method, please skip to step 7.
   • If you want to create cluster or add agent nodes using the IP address method, please perform steps 3, 4, 5, and 6.

   Example

   Important: The hostnames and IP addresses mentioned in this table are used in the examples for the steps below. Please make sure to replace the hostnames and IP addresses with your machine's hostnames and IP addresses.

   Hostname	IP Address	Role
   sdwan-node01	10.123.45.67	control plane
   sdwan-node02	10.123.45.68	agent1
   sdwan-node03	10.123.45.69	agent2

3. Using ssh, log into SD-WAN collector control plane node as sevone.

   $ ssh sevone@<SD-WAN collector 'control plane' node IP address or hostname>
   

   Example

   $ ssh sevone@10.123.45.67
   

4. Stop / reset the running cluster.
   Important: Please perform this step on control plane node and all agent nodes you want to add.

   $ sevone-cli cluster down
   

5. Log into SD-WAN collector control plane node as sevone and add nodes by executing the following command.

   $ sevone-cli cluster worker add <IP address for node>
   

   Important:

   • Please add agent nodes using the IP address only.
   • When adding a new agent node to your cluster, repeat step 5 every time.
   • Please do not run sevone-cli cluster worker remove command when there is no k3s cluster running.
6. The following spins up your Kubernetes cluster.

   $ sevone-cli cluster up
   

   Important: If you want to add more nodes to your cluster, execute the following commands in the same order as shown below.

   1. $ sevone-cli cluster down

      command on control plane node every time.

   2. $ sevone-cli cluster worker add <IP address for node>

      command.

   3. $ sevone-cli cluster up

      command.
   Important: The message FAILED - RETRYING: Wait for kubernetes node to be up means that kubernetes node is trying to come up and it may take a long time. If all retries are exhausted and kubernetes node is unable to come up, the command will fail automatically. Please contact IBM SevOne Support for help.
7. Verify that your control plane and agent node(s) are Ready and have been added to the Kubernetes cluster.

   $ kubectl get nodes
   
   NAME                             STATUS   ROLES                 AGE     VERSION
   <your 'control plane' hostname>  Ready    control-plane,master  2m45s   v1.27.1+k3s1
   <your 'agent1' hostname>         Ready    <none>                2m45s   v1.27.1+k3s1
   <your 'agent2' hostname>         Ready    <none>                2m45s   v1.27.1+k3s1
   ...
   <your 'agent<n>' hostname>       Ready    <none>                2m45s   v1.27.1+k3s1
   

   Example

   $ kubectl get nodes
   
   NAME          STATUS  ROLES                 AGE     VERSION
   sdwan-node01  Ready   control-plane,master  2m45s   v1.27.1+k3s1
   sdwan-node02  Ready   <none>                2m45s   v1.27.1+k3s1
   sdwan-node03  Ready   <none>                2m45s   v1.27.1+k3s1
   

   Important: You are now ready to configure your SD-WAN collector.

1. Using ssh, log into SD-WAN Versa collector control plane node as sevone.

   $ ssh sevone@<SD-WAN collector 'control plane' node IP address or hostname>
   

   Example

   $ ssh sevone@10.49.12.2

2. Copy SSH keys to SevOne NMS and install GUI.

   $ ssh-copy-id support@<SevOne NMS IP Address> && sevone-cli solutions guii
   

   Example

   $ ssh-copy-id support@10.49.13.194 && sevone-cli solutions guii
