Getting Started with Connectivity Services Director

 

Based on your network deployment needs and configuration settings, you might require different service types, such as E-Line, IP, E-LAN, or RSVP LSP services, to be applied on devices in your topology. It is essential to discover or add the devices that you want to be administered using Connectivity Services Director to the application database, before you can enable and define services. You must configure the basic and mandatory device settings such as routing instances, routing protocols, and administrative groups before they are imported or discovered for additional modifications, such as configuration of services and using the network management application.

When you install Connectivity Services Director, the single application package installs the capabilities for configuring network services, such as E-Line, IP, and E-LAN, configuring MPLS and RSVP label-switched path (LSP) services, configuring Precision Time Protocol (PTP) and synchronous Ethernet services, configuring the OAM (Operations, Administration and Maintenance) functionality, and configuring class of service (CoS) profiles. To install Connectivity Services Director, see the Installation Instructions for Connectivity Services Director, Release 2.1 section in Junos Space Connectivity Services Director Release Notes, Release 2.1.

The following workflow describes the tasks that you need to perform after the installation of the application to enable effective and streamlined management, provisioning, and troubleshooting of devices and services configured using Connectivity Services Director.

After you install the Connectivity Services Director application, follow the tasks given below to enable effective management, provisioning, and troubleshooting of devices and services using the application:

  1. Discover devices using Connectivity Services Director GUI or the Junos Space Platform workspace. See Discovering Devices for instructions on discovering devices using Connectivity Services Director. See Discovering Devices in the Junos Space Network Management Platform User Guide for instructions on discovering devices using the Junos Space Platform workspace.

    Note

    Ensure the following before you add a device using device discovery:

    • SSH v2 is enabled on the device. To enable SSH v2 on a device, run the following CLI command:

      set system services ssh protocol-version v2
    • The NETCONF protocol over SSH is enabled on the device. To enable the NETCONF protocol over SSH on a device, run the following CLI command:

      set system services netconf ssh
    • The device is configured with a static management IP address that is reachable from the Junos Space server. The IP address can be in-band or out-of-band.

    • A user with full administrative privileges is created on the device for the Junos Space administrator.

    • If you use SNMP to probe devices as part of device discovery, ensure that SNMP is enabled on the device with appropriate read-only V1/V2C/V3 credentials.

  2. Discover the roles of devices and assign network-provider edge (N-PE) roles as necessary. To prestage devices and assign device roles, see Discovering Device Roles and Excluding Devices from N-PE Role Assignment.

  3. Create service templates. Templates provide a powerful mechanism to configure advanced service-related options that are not exposed via the service order creation workflow. Templates are attached to a service definition. To work with service templates, see Service Templates Workflow and Applying a Service Template to a Service Definition.

  4. Review predefined service definitions that are available by default, and determine whether you want to create a new customzied service definition. A service definition specifies the attributes that are common among a group of service orders that have similar service requirements. To work with service definitions, see Predefined Service Definitions, Creating an E-Line Service Definition, Creating a Multipoint-to-Multipoint E-LAN Service Definition, Creating a Point-to-Multipoint E-LAN Service Definition, Creating a Full-Mesh IP Service Definition, and Creating a Hub-and-Spoke (One Interface) IP Service Definition.

  5. Create customers that denote the users to be associated with service orders. New customers must be identified to the system before you can provision and activate a service order for them. To create customers, see Adding a New Customer.

  6. Create class-of-service profiles to prioritize the traffic flow and define policies for handling received packets to avoid network congestion and traffic disruption. See Creating and Managing Wired CoS Profiles.

  7. Create service orders for the types of protocols that your network environment requires for optimal and cohesive management of large numbers of devices. A service order is an instance of the service definition that completes the definition for a specific customer’s use. To work with service orders, see Creating a Service Order.

  8. Deploy service orders to propagate the service configuration to the corresponding devices. To transfer service order configurations to devices and apply the settings on the devices, see Deploying Services Configuration to Devices and Managing Service Configuration Deployment Jobs.

  9. Perform audit operations, such as functional and configuration audit, to examine the status of interfaces, LDP sessions, neighbor links, and endpoints of E-Line services. You can also identify whether the service configuration on the device has been changed out of band. In addition, you can use op scripts to perform any function available through the remote procedure calls (RPCs) supported by either the Junos XML management protocol or the Junos XML API. For more information, see Performing a Functional Audit, Performing a Configuration Audit, and Troubleshooting N-PE Devices Before Provisioning a Service.

  10. Monitor the health (working condition), operating efficiency, traffic-handling capacity, and performance status of the managed devices and configured services. Several monitors or widgets are displayed to enable you to track, diagnose, and rectify problems and discrepancies associated with services configured on devices. To evaluate and diagnose the services, traffic-flow, and device states, see Service Monitoring Capabilities in Connectivity Services Director.

  11. View information about the health of your network and changing conditions of your equipment. Use Fault mode to find problems with equipment, pinpoint security attacks, or to analyze trends and categories of errors. For example, if you find that a particular device or a service has recorded a large number of critical or major alarms, you can then navigate to the appropriate device settings page or service order page to correct and modify the attributes or diagnose the problems that might be generating the alarms. To view alarms and events, see Understanding Fault Mode in Connectivity Services Director.
