Cisco® announces Cisco Enhanced Device Interface (EDI) 2.2, providing new enhancements for device configuration and troubleshooting. Cisco Enhanced Device Interface is accessible through an intelligent command-line interface (CLI) and an Extensible Markup Language programmatic interface (XML PI).
Cisco Enhanced Device Interface is an external implementation of the network element interface and provides two major features: an enhanced CLI user interface and an XML PI. The CLI user interface is a CLI-like command emulator with added features and enhanced for usability; it allows the user to manage multiple network elements from a single location, individually or as a group. The exposed CLI is based on the CLI of the managed network element; in this release, Cisco IOS
® Software, Cisco PIX
® OS, and Cisco Catalyst
® OS CLIs are supported.
The purpose of the XML PI in Cisco Enhanced Device Interface is to provide a programmatic interface to be used by management applications for configuring Cisco devices. The programmatic interface has a well-defined set of operations based on the IETF NETCONF Internet draft along with a supporting data model defined using the XML schema language. Customers that configure and monitor devices through scripting tools and do not wish to make use of the data model may continue to use CLI commands as payload in the management operations supported over the XML PI.
Cisco Enhanced Device Interface is aimed to increase end-user as well as management application-developer productivity in the areas of device configuration and troubleshooting. Table 1 describes the features of Cisco Enhanced Device Interface 2.2.
Table 1. Features of Cisco Enhanced Device Interface 2.2
OS parser emulation (CLI syntax check command context validation)
This feature helps eliminate common user errors.
This capability allows for the definition of administrative domains. Access control can be performed at the administrative domain level. This feature simplifies configuration and administrative tasks.
Group least common denominator CLI (that is, a common CLI)
This feature allows users to perform group operations without the possibility of generating an unsupported command.
This capability allows users to simultaneously apply changes to one or more devices by simply selecting the context. It provides a single point for network configuration.
Helps enable users to push commands to various types of platforms (Cisco Catalyst OS, Cisco IOS Software, and Cisco PIX OS) that have variation in CLI commands.
XML programmatic interface, IETF NETCONF operations
The standards-based interface promotes consistency.
XML command data model
Command structure and syntax can be programmatically read; simplifies interaction with Cisco devices.
Operational data model
Provides applications with an XML interface to retrieve from network elements the operational data that is available through the CLI show commands. Allows you to create a model specification file, an XML file, and an XSD.
Provides Cisco EDI with the capability to verify the configuration commit. It displays details about the success or failure of the configuration on the given network.
This helps you ensure that the configuration commit is successful and complies with the candidate configuration.
XML PI Java SDK
Provides Java APIs over XML PI. Cisco EDI provides Java client API libraries that take Java objects as inputs and return Java objects; you can use these APIs to develop your own applications. You can also use these APIs in existing applications.
Cisco Enhanced Device Interface 2.2 will begin shipping May 10, 2007.
