Getting Started with JET

Configure JET Interaction with Linux OS

In cRPD, JET service is enabled on TCP port 40051 and binds to loopback address 127.0.0.1 or ::1. To access JET service remotely, set up the SSH tunneling into the cRPD container using either username and password or SSH keys.

Remote access to JET service is secured using SSH. For more information on enabling SSH using port forwarding, see Establishing an SSH Connection for a NETCONF Session and cRPD.

The maximum number of JET connections supported is 512.

Maximum Number of JET Connections

To setup maximum number of JET connections:

  1. Access the cRPD Linux shell.
  2. Use the command to add the connections:

    root@crpd1:~# ulimit -n 519

  3. Restart ssh on cRPD.

    /etc/init.d/ssh restart

  4. Re-establish ssh tunnel from Host Ubuntu to cRPD.
  5. Connect up to 512 simultaneous JET Connections.

Compile IDL Files

To download and compile the IDL files:

  1. Download the IDL jet-idl-20.4R1.12.tar.gz file from the Juniper Networks website at www.juniper.net/support/downloads/.
  2. Unpack the IDL file.

    For example:

  3. Install the grpcio module.

    apt-add-repository universe

    apt-get update

    apt-get install python-pip

    python -m pip install grpcio

    python -m pip install grpcio-tools

  4. Compile python and gRPC modules for Authentication and Management Service proto files.

    For example:
