New and Changed Features

Chef for Junos OS Release 11.10 introduces support for the following features:

  • Support for MX Series routers.
  • Providers for the netdev cookbook—The netdev cookbook contains resource types that support configuration of the following Junos OS elements:

    • Physical interfaces—Physical Ethernet interfaces attributes, such as administrative state, description, speed, duplex mode, and MTU with the netdev_interface resource
    • Layer 2 Ethernet switching services—Logical Ethernet switching interface attributes, such as description, VLAN membership, and port mode (access or trunk) with the netdev_l2_interface resource
    • Link aggregation groups (LAGs)—LAG interface attributes, such as name, member links, LACP mode, and minimum up links required with the netdev_lag resource
    • VLANs—VLAN attributes, such as name, ID, and description with the netdev_vlan resource
    • Configuration at any hierarchy level—Custom configuration with the netdev_group resource

    Note: The Juniper Networks OCX1100 switches support only the netdev_interface physical interface resource.

    Chef for Junos OS Includes the providers for these resources that are specific to Junos OS. The Chef client uses the providers to implement the configuration described by the resources on the Juniper Networks device the Chef client is running on.

    The netdev cookbook is maintained by Chef and is available at the Chef supermarket website at

    [See Chef for Junos OS Overview].

  • Native Chef client and Ohai—The Chef client and Ohai run natively on the supported device. They are included in the Chef package you install. For packages built with the Junos SDK, the following three packages are installed:

    • Chef client 11.10—Includes both the Chef client and Ohai
    • junos-ez-stdlib—Libraries used by the netdev cookbook providers and by Ohai
    • Ruby—Ruby Interpreter version compatible with the Chef client
    For packages built with the Juniper Extension Toolkit (JET), only one package is installed, JET app chef, that includes junos-ez-stdlib and the Ruby Interpreter.
