Overview of Configuring and Managing Optical ILAs from Connectivity Services Director Using DMI

Connectivity Services Director uses the Juniper Networks Device Management Interface (DMI) to the managed devices to collect the data. If you have a Junos Space fabric, Connectivity Services Director balances the load of polling the managed devices across the nodes in the fabric. Direct SNMP communication is absent between the NMS server such as Connectivity Services Director and the optical ILA because of IPLC design.

The requirements from Connectivity Services Director are as follows:

  • Connectivity Services Director needs to be able to retrieve the optical ILA performance, fault, and image-upgrade status. In addition, Connectivity Services Director must be able to send configuration and upgrade commands to the optical ILA. IPLC can set or get the optical ILA configuration and management parameters through SNMP (or any other method), save them locally and expose these through the Junos OS CLI. Connectivity Services Director is able to access these parameters through DMI.

  • This implementation requires an optical ILA management client in optical ILA and optical ILA management server in IPLC. The management server queries the parameters periodically. Similarly, the CLI commands are used to set parameters related to optical ILA and initiate operations such as upgrade, which are sent as SNMP messages to the optical ILA client.

The following are examples of various configuration settings, and Set and Get operations required on an optical ILA.

Configuration Settings Performed Using the CLI

  • Saving configuration

  • Restoring configuration

  • Resetting the OS

  • Starting the firmware upgrade

  • Restoring EDFA defaults

  • Resetting the EDFA

Set Parameters for SNMP

  • Temperature threshold parameters

  • Addition and deletion of SNMP users

  • Mode configuration (auto or debug)

  • EDFA parameters (such as mode, gain, tilt, and LOS action)

  • Optical power parameters (input and output LOS thresholds, and LOS hysteresis)

  • OSC parameters (enable, add or drop power value, thresholds, and LOS hysteresis)

Get Parameters for SNMP

  • Optical ILA part number, serial number, and uptime

  • Temperature

  • Fan speed

  • Firmware upgrade status

  • SNMP user information

  • Mode EDFA (module type, part number, working status, gain, and temperature)

  • Optical power (input power and output power)

  • VOA attenuation

  • OSC (index)


  • Viewing active alarms

  • Viewing historical alarms
