Understanding Edge Services Director and the Management Lifecycle Modes
Junos Space Edge Services Director is a Junos Space application for management of services interfaces of MX Series routers, such as adaptive services interfaces and multiservices interfaces, that provide specific capabilities for manipulating traffic before it is delivered to its destination. Services interfaces enable you to add services to your network incrementally. Providing full network lifecycle management, Edge Services Director simplifies the discovery, configuration, visualization, monitoring, and administration of large networks. Operators can quickly deploy a network by using it, configure it optimally to improve network uptime and maximize resources, and respond agilely to the needs of applications and users.
The Edge Services Director user interface is based on the network management lifecycle. The interface provides five main working modes that are aligned to the network management lifecycle, and a sixth mode for working with Edge Services Director itself. Each mode provides access to different tasks:
Build mode—In Build mode, you can create services, policies, and filters for devices that are managed by Edge Services Director. You can define service templates and attributes of different services. You can also specify policies and filters to classify and control the manner in which packets must be handled by the various services. Configuring a policy has a major impact on the flow of routing information or packets within and through the router.
In Gateway view of Build mode, you create the network managed by Junos Space Edge Services Director by bringing devices under the administration of the network management application and retrieving the device settings to save in the Edge Services Director database. It provides you with the ability to use device discovery to bring devices under Edge Services Director management, to customize your view of the devices, to configure devices, and to perform some common device management tasks. In Device view of Build mode, you can perform software upgrades to devices and perform several device management and configuration file management tasks. You can also back up the Edge Services Director database that contains all the configuration parameters of devices, settings that enable monitoring and management of devices and services, and reports that contain statistics and graphs of the tracked system states. You can restore the data backed up to a different server that runs the Edge Services Director application.
Deploy mode—Deploy mode enables you to deploy configuration changes to devices. You can create a deployment plan for each of the service planning templates, such as the ones defined for ADC or stateful firewall (SFW) services, and the policy or filter templates, such as the packet filter or SFW policy, that you have created. A deployment plan contains details about the settings and configuration parameters that must be propagated and provisioned on the SDGs managed by Edge Services Director. You can also create, update, display, publish, and commission packet filters, stateful firewall policies, and CGNAT policies present on discovered and managed SDGs.
Monitor mode—Monitor mode in Edge Services Director provides visibility into the behavior and performance of your network. Edge Services Director monitors its managed devices and maintains the information it collects from the devices in a database. Monitor mode displays this information in easy-to-understand graphs and in tables that you can sort and filter, allowing you to quickly visualize the state of your network, spot trends developing over time, and find important details.
Fault mode—Fault mode shows you information about the health of your network and changing conditions of your equipment. Use Fault mode to identify problems with equipment, pinpoint security attacks, or analyze trends and categories of errors. Edge Services Director correlates traps, which describe a condition, into an alarm. Alarms are ranked by their impact on the network.
Report mode—Use Report mode to generate reports from the data that Edge Services Director stores about network performance, status, and activity. In Report mode, you can create standardized reports from the monitoring and fault data collected by Network Director. An essential part of the network management lifecycle, reporting provides administrators and management insight into the network for maintenance, troubleshooting, and trend and capacity analysis, and generates records that can be archived for compliance requirements.
View pane—On the View pane, Edge Services Director provides you with a unified, hierarchal view of your wired, wireless, and virtual networks in the form of a expand tree that is expandable and collapsible. You can choose from five views, or perspectives, of your network—Dashboard view, Location view, Device view, Gateway view, and Service view. By selecting both a view and a node from the tree, you indicate the scope over which you want an operation or task to occur. The Dashboard view provides a summary, encompassing a pictorial representation of the health and performance of devices and services in your network, which enables you to analyze and troubleshoot the parameters that are causing traffic-handling errors.
System-level tasks include viewing the Edge Services Director user and system audit trail, managing jobs, and gathering logs for troubleshooting. The dashboard enables you to allow the operators to quickly monitor health and status of the managed service delivery gateways (SDGs) through several widgets and monitors. The sections or frames on the dashboard allows the operator to understand the device problem or fault at macro level (comprehensive and widespread network health and status) to micro level (individual SDG health and status). The health representation of the SDGs can be customized based on the monitoring properties defined in SDG templates.
