4-Node Setup

4-Node setup includes:

Hardware Requirements

The Contrail Command server, on which AppFormix Platform is installed has the following minimum requirements.

• CPU: 16 cores (virtual or physical)

• Memory: 64 GB

• Storage: 2 TB (recommended)

Requirements

• Install Centos 7.7 on all nodes.

• Have your AppFormix license from Juniper available. This will need to be added on the Contrail Command server in the same folder together with Appformix.

Server requirements and supported platforms are listed in the installation guide and release notes.

Download and Install AppFormix and AppFormix Flows on the Contrail-Command Node

To install AppFormix using Contrail Command:

1. Download AppFormix from

   https://support.juniper.net/support/downloads/.

   Note:

   See Table 1 for Contrail, AppFormix, and AppFormix Flows version mapping.

   Download the AppFormix Flows images by selecting 1.0 from the drop-down list:

   Figure 1: Download AppFormix Flows Images

   • Copy the AppFormix tar.gz files to the /opt/software/appformix/ directory on the Contrail Command server.

   • Copy your AppFormix license to the /opt/software/appformix/ directory.

   • Copy the two appformix-flows files to the /opt/software/xflow directory.

2. Verify the command_servers.yml file was added before installing Contrail Command as specified in Installing Contrail Command. This makes /opt/software/appformix available in contrail-command Docker.

   Add the following statements to the command_servers.yml file. They must be placed after the "---" at the very top of the file or as the last two lines at the very bottom of the file.

3. From Setup, select AppFormix Nodes.

   Figure 2: AppFormix Nodes Setup

4. From AppFormix Nodes, the appformix_platform role is selected by default.

   Optionally, select appformix_bare_host and appformix_network_agents roles as needed.

5. Starting with Contrail networking release 1910, AppFormix Flows is integrated in the Contrail Command UI. For the AppFormix node, keep the appformix_platform role default.

   Enter the following values:

   Out-of-Band Provisioning:

   • Virtual IP Address—This is the IP address of the load balancer node for AppFormix Flow collectors.

   • Available Servers—Select the server on which AppFormix Flows node is to be installed.

   In-Band Provisioning:

   • CIDR—Enter the underlay telemetry infrastructure subnet. In-band interface on the AppFormix Flows node is assigned an IP address from this subnet.

   • VLAN-ID—Enter the VLAN ID used for the telemetry infrastructure network.

   • Management Virtual IP Address—Enter an unused IP address which will be used as the management IP Address. Contrail Command uses this IP address to connect to the AppFormix Flows node.

   • Virtual IP Address—The IP address is populated by default and is usually the third IP Address from the CIDR range (telemetry subnet). However, you can change the IP address if needed. This IP address is used as the collector destination IP address for the sFlow target on TOR switches.

   • (Optional) Retention Period—Time duration in seconds that you want to keep the collected data. Default is 7200 s.

   • (Optional) Max Retention Bytes—Maximum size of the data to be collected. Default is 0 which indicates unlimited size.
