Note:

Before you begin the configuration, make sure that you download the image file for your virtualization platform. See your platform documentation for details.

Note:

We recommend that you run Apstra and Apstra Flow on the same version. This ensures compatibility and prevents potential issues that can arise between the different versions.

Note:

You can install KVM with Virtual Machine Manager or with the CLI.

Let's get started!

Configure Your Network

Note:

If you have a DHCP server, by default, the Apstra Flow VM automatically obtains an IP address. To assign a static IP address instead, SSH to the VM and skip to Step 2 in this procedure. Otherwise, start at Step 1.

If the console is already started, click the play button at the top of the VM summary.
Login to the CLI. The default credentials for the Apstra Flow console are: user=apstra and password=apstra. You'll want to change this password after the VM is deployed.

Change the directory to /etc/netplan.

content_copy zoom_out_map
apstra@apstra-flow:~$ cd /etc/netplan/
apstra@apstra-flow:/etc/netplan$ ls
00-installer-config.yaml  01-netcfg.yaml

Add an IP address to your network interface. Edit the 01-netcfg.yaml file as follows:

content_copy zoom_out_map
apstra@apstra-flow:/etc/netplan$ sudo vi 01-netcfg.yaml 

content_copy zoom_out_map
#
 network:
  version: 2
  ethernets:
    eth0:
      dhcp4: false
      addresses:
      - 10.19.10.100/24 <replace with static IP, if desired>
      #  - 192.0.2.1
      #  search: []
      routes:
      - to: 10.11.0.0/16 <add your DNS settings>
        via: 10.19.10.1  <-
      routes:
      - to: 0.0.0.0/0
        via: 172.25.90.1 <configure the default route>

Enter sudo netplan apply to power up your network.

content_copy zoom_out_map
apstra@apstra-flow:/etc/netplan$ sudo netplan apply 

content_copy zoom_out_map
** (generate:16454): WARNING **: 14:16:45.231: Permissions for /etc/netplan/00-installer-config.yaml are too open. 
Netplan configuration should NOT be accessible by others.

** (generate:16454): WARNING **: 14:16:45.231: Permissions for /etc/netplan/01-netcfg.yaml are too open. 
Netplan configuration should NOT be accessible by others.

(you can ignore permissions errors, or fix if desired)

You can now SSH to the VM with your configured IP address and Apstra credentials, as shown in the following example:

content_copy zoom_out_map
username@username-mbp ~ % ssh apstra@172.25.90.2
apstra@172.25.90.2's password: 
Welcome to Ubuntu 22.04.3 LTS (GNU/Linux 5.15.0-86-generic x86_64)

Note:

Optionally, you can create a VM with a multinode cluster for scaling and high availablity. See Create an OpenSearch Multinode Cluster (Optional) for more information.

Configure the Flow Collector

You can configure the collector to specify a hostname or IP address, the port the collector is listening on, and username and password for the Apstra controller.

To configure the flow collector:

SSH to the Flow VM with the default VM username and password (apstra/apstra).
Modify the /etc/juniper/flowcoll.yml file as follows:
- EF_JUNIPER_APSTRA_API_ADDRESS: "10.28.111.3" (replace this value with your IP)
- EF_JUNIPER_APSTRA_API_PASSWORD: "admin"
- EF_JUNIPER_APSTRA_PORT: "443" (default port)
- EF_JUNIPER_APSTRA_API_TLS_ENABLE: "true"
- EF_JUNIPER_APSTRA_API_USERNAME: "admin"
Note:
By default, Apstra Flow reports the interface index values, like index:14. To enrich the reporting with actual interface names, like xe-0/0/1, configure Apstra Flow to query devices through SNMP using the following settings:
- EF_PROCESSOR_ENRICH_NETIF_SNMP_COMMUNITIES: public
- EF_PROCESSOR_ENRICH_NETIF_SNMP_ENABLE: “true”

You completed configuring your network and flow collector. If you have an extra-large or custom deployment, continue to Create an OpenSearch Multinode Cluster (Optional). Otherwise, continue to Apply Your License.
