    If the information in the latest release notes differs from the information in the documentation, follow the product Release Notes. Juniper Networks Books publishes books by Juniper Networks engineers and subject matter experts. These books go beyond the technical documentation to explore the nuances of network architecture, deployment, and administration.

  • Page 19: Merging A Full Example

    If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example is a full example. In this case, use the load merge command. If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In this case, use the load merge relative command.

  • Page 20: Merging A Snippet

    Merging a Snippet To merge a snippet, follow these steps: 1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the file with a name, and copy the file to a directory on your routing platform. For example, copy the following snippet to a file and name the file ex-script-snippet.conf.

  • Page 26: Virtual Chassis Fabric Overview

    Virtual Chassis Fabric Hardware Overview | 8 Virtual Chassis Fabric Overview The Juniper Networks Virtual Chassis Fabric (VCF) provides a low-latency, high-performance fabric architecture that can be managed as a single device. VCF is an evolution of the Virtual Chassis feature, which enables you to interconnect multiple devices into a single logical device, inside of a fabric architecture.
  • Page 27 Figure 1: VCF Spine-and-Leaf Architecture A VCF is based on either QFX5100 or QFX5110 switches as the spine devices, as follows: You can configure a VCF with QFX5100 switches as the spine devices, referred to as a QFX5100 VCF. In an optimal QFX5100 VCF configuration, the leaf devices are also QFX5100 switches. You can, however, also create a mixed QFX5100 VCF by including any combination of QFX5100, QFX3600, QFX3500, and EX4300 switches as leaf devices.

  • Page 28: Understanding Virtual Chassis Fabric Configuration

    Flexibility—You can easily expand the size of your VCF by adding devices to the fabric as your networking needs grow. Investment protection—In environments that need to expand because the capabilities of a traditional QFX Series Virtual Chassis are maximized, a VCF is often a logical upgrade option because it enables the system to evolve without having to remove existing, previously purchased devices from the network.

    mixed mode to participate in the VCF. You can optionally avoid the downtime that accompanies a leaf device reboot by manually setting the leaf device into fabric mode and into or out of mixed mode, zeroizing the device at that point if necessary, and manually rebooting the device before interconnecting it into the VCF.

  • Page 31: Configuration File Management In A Vcf

    The default primary-role priority value for all devices is 128. You should always configure two spine devices with the highest primary-role priority to ensure the Routing Engine role is assigned to a spine device. In a nonprovisioned VCF, you must manually configure every VCP. Configuration File Management in a VCF You configure a VCF by logging onto the primary Routing Engine and making configuration changes.

  • Page 32: Virtual Chassis Fabric Hardware Overview

    Configuring a Nonprovisioned Virtual Chassis Fabric | 380 Virtual Chassis Fabric Hardware Overview The Juniper Networks Virtual Chassis Fabric (VCF) spine-and-leaf architecture supports two types of hardware configurations based on the switch model used as the spine in the VCF.
  • Page 33 VCF installations with a mixture of models are called mixed mode. For example, a mixed mode QFX5100 VCF might contain a EX4300 or QFX3600 as leaf devices. Mixed mode devices must be configured before joining the VCF and are not eligible for the auto-provisioned configuration (plug and play). Adding a device configured as mixed mode to a VCF can cause those devices to be marked inactive if the other devices are not also configured as mixed mode.

Auto-sense—The ports auto-sense the transceiver and set the port speed to match. The Packet Forwarding Engine on the switch is restarted when you issue system mode changes.

    CAUTION: Take care when changing the channelization mode from Flexi-pic to default. If you have existing ports that are channelized in Flexi-pic mode, remove the channelization from the interface before changing the system mode. Changing the Flexi-pic mode to the default mode with channelized ports causes the ports to go down, log a system log error, and remain down.

    BEST PRACTICE: When adding a leaf device to an existing VCF, interconnect the new device to the spine member that is in the primary Routing Engine role first, which is the most efficient way to synchronize the new member with the current VCF configuration and state. Interconnecting a new member only to the backup or another spine member can cause flooding of messages within the VCF as the primary tries to synchronize the new member through other leaf and spine member VCP links.
  • Page 422 [edit virtual-chassis] user@device# set member 3 serial-number OU81234567890 role line-card The set virtual-chassis member member-id fabric-tree-root configuration statement specifies that only certain devices will be root nodes in the multicast distribution trees (MDTs) created for directing traffic within the VCF. This configuration item preempts the default VCF behavior to create one MDT for every device in the VCF with that device as a root node.

    NOTE: We recommend setting the fabric and mixed mode settings before interconnecting your devices into a VCF to avoid the following issues: Incurring downtime as the devices reboot to commit the mixed mode or fabric settings. Manually correcting potential issues related to VCF formation because the device did not immediately join the VCF.

This step requires a VCF reboot, which incurs some downtime.

    BEST PRACTICE: When adding a leaf device to an existing VCF, interconnect the new device to the spine member that is in the primary Routing Engine role first, which is the most efficient way to synchronize the new member with the current VCF configuration and state. Interconnecting a new member only to the backup or another spine member can cause flooding of messages within the VCF as the primary tries to synchronize the new member through other leaf and spine member VCP links.

  • Page 555 TIP: By default, all access ports are configured as Ethernet interfaces. If you insert a Fibre Channel transceiver, the LEDs do not light until you configure the port as a Fibre Channel interface in Junos OS. Likewise, the LEDs do not light if you insert an Ethernet transceiver in a port configured as a Fibre Channel interface.
