QFabric System Initial and Default Configuration Information

Once you install the hardware for the QFabric system, you can configure the Junos operating system (Junos OS) to begin using the system. This topic discusses which setup activities you need to perform and which activities are handled automatically by the QFabric system.

The fabric manager Routing Engine in the Director group automatically handles some of the initial setup activities, including:

• Assignment of IP addresses and unique identifiers to each QFabric system component by way of the management control plane
• Inclusion of all QFabric system devices within the default partition
• Establishment of interdevice communication and connectivity through the use of a fabric provisioning protocol and a fabric management protocol

The initial configuration tasks you need to perform to bring up the QFabric system and make it operational include:

• Converting any standalone devices, such as QFX3500 and QFX3600 devices, to Node device mode (see Converting the Device Mode for a QFabric System Component)
• Setting up the QFabric system control plane cabling, topology, and configuration
  • To set up the control plane cabling, topology, and configuration for the QFX3000-G QFabric system, see Example: Configuring the Virtual Chassis for the QFX3000-G QFabric System Control Plane.
  • To set up a copper or fiber-based control plane cabling, topology, and configuration for the QFX3000-M QFabric system, see Example: Configuring EX4200 Switches for the Copper-Based QFX3000-M QFabric System Control Plane.
• Accessing the Director group through a console connection, turning on the devices, and running through the initial setup script (see Performing the QFabric System Initial Setup on a QFX3100 Director Group), which prompts you to:
  • Set IP addresses for the Director devices in the Director group.
  • Set an IP address for the default partition.
  • Add the software serial number for your QFabric system. (Review the e-mail containing the software serial number that you received from Juniper Networks when you purchased your QFabric system.)
  • Set the starting MAC address and the range of MAC addresses for the QFabric system. (See Generating the MAC Address Range for a QFabric System for this information.)
  • Set a root password for the Director devices.
  • Set a root password for the QFabric system components, such as Node devices, Interconnect devices, and infrastructure.
• Logging into the default partition by using the IP address you configured when you ran the Director group initial setup script (See Gaining Access to the QFabric System Through the Default Partition)
• Configuring basic system settings for the default partition, such as time, location, and default gateways

  Note: Unlike other Juniper Networks devices that run Junos OS, a QFabric system does not have a default factory configuration (containing the basic configuration settings for system logging, interfaces, protocols, and so on) that is loaded when you first install and power on the Director devices. Therefore, you must configure all the settings required for your QFabric system through the default partition CLI.

• Configuring aliases for Node devices (see Configuring Aliases for the QFabric System)
• Configuring VLANs and interfaces for the QFabric system devices
• Configuring redundant server Node groups to provide resiliency for server and storage connections (see Configuring Node Groups for the QFabric System)
• Configuring a network Node group to connect the QFabric system to external networks (see Configuring Node Groups for the QFabric System)
• Configuring the port type on QFX3600 Node devices (see Configuring the Port Type on QFX3600 Node Devices)
• Configuring routing protocols to run on the network Node group interfaces and reach external networks

  Note: When you configure routing protocols on the QFabric system, you must use interfaces from the Node devices assigned to the network Node group. If you try to configure routing protocols on interfaces from the Node devices assigned to server Node groups, the configuration commit operation fails.

• Generating and adding the license keys for the QFabric system (see Generating the License Keys for a QFabric System and Adding New Licenses (CLI Procedure))
