Junos Fusion Configuration

In the previous article, we talked about Basic Understanding Junos Fusion where a head start so that you know some terminologies and its behavior. In this article, we are going to share a sample configuration to get it works with some verification commands. Let get started!

Network Connectivity

As usual, network connectivity is the important part where you can get understand better about the configuration.

As above diagram demonstrated, we have Juniper MX204 and QFX5110 where both of them connect to each other with 2 physical ports.

Network Configuration

  1. Juniper MX204 – The Aggregate

interfaces {
    et-0/0/2 {
        description "To-QFX5110#et-0/0/48";
        cascade-port;
    }
    et-0/0/3 {
        description "To-QFX5110#et-0/0/49";
        cascade-port;
    }
}

chassis {
    network-services enhanced-ip;
    satellite-management {
        fpc 101 {
            serial-number WS3712341234;
            alias QFX5110-1;
            cascade-ports [ et-0/0/2 et-0/0/3 ];
        }
        upgrade-groups {
            Group1 {
                satellite 101;
            }
        }
    }
}

Now, in the operational mode, issue below commands.

To automatically install satellite software on Satellite device. 

request system software add /tmp/satellite-18.4R2.7-signed.tgz upgrade-group Group1

To tell MX204 which ports are used to connect to satellite switches.

request chassis satellite interface et-0/0/2 device-mode satellite
request chassis satellite interface et-0/0/3 device-mode satellite

2. Juniper QFX5110 – The Satellite

  • Log in to the device using the console port.
  • Zeroize the device:
request system zeroize
After the satellite rebooted, it will then automatically joining Fusion.
 
3. Verification
Issue below command on aggregate device to verify Fusion status.
