Overview -- ANA VNE

The following topics introduce you to the Cisco Active Network Abstraction (ANA) Virtual Network Element (VNE):

This chapter also describes how this document is organized and the information that it contains. See VNE Reference Organization and Content for more details.

What is a VNE?

A virtual runtime representation of a single network element as a modeled component. VNEs communicate with one another to present Network Service Management applications' with a single, common device abstraction for network element discovery, configuration, status collection, fault analysis and other basic network (FCAPS) functions. VNEs can be extended to support new application functionality.

How Can I Download VNEs?

All the Cisco VNEs are part of ANA 4.0 DVD. You can download the non-Cisco VNEs, from Cisco.com:

This document contains the following sections that give you detailed information on the supported network elements in ANA 4.0.

This table lists all of the supported device families, device types and the respective sysObjectID. It also contains supported Network Resource Management components. In addition to these, this table guides you to select the correct ANA Schemes.

The information collected by a VNE and populated in its model depends on the scheme you choose while adding the VNE to an AVM. ANA supports two schemes: Foundation and MPLSIOXSR.

The scheme you should use, depends on the type of network element you are adding. The supported ANA schemes are:

•

Foundation—Used for all Cisco devices and other vendor devices, such as Redback SMS (1800, 10000) and Alcatel 4.x, etc.

•

MPLSIOSXR—Used only for Cisco devices that are running Cisco IOS-XR image. For ANA 4.0, this scheme can be used for Cisco XR 12000 series and Cisco CRS-1.

For information on adding a VNE to AVM, see Cisco Active Network Abstraction 4.0 User and Administration Guide on Cisco.com:

This table contains the details about the supported network elements for a particular device series and the corresponding sysObjectIDs.

This table also contains the verification level for each of the supported network elements.

This table contains the details about the supported software and its verification level for the supported software.

This table contains the details about the supported module for a specific network element. It also contains the verification level for each of the supported modules.

This table contains the details of the supported network technologies, such as ethernet, MPLS, and so on. It links to a supported attributes' tables that lists all of the network technology attributes. These attributes are supported for a device family.

The supported attributes table also includes information on the ANA polling intervals. The polling intervals depend on the type of information that is being queried on the network elements.

The intervals represent the amount of time between investigations of the network element for the data specified. The default polling group has the following settings:

•

Status—Sets the polling rate for status-related information, such as network element status (up or down), port status, admin status and so on. The information is related to the operational and administrative status of the network element. The default setting is 180 seconds.

•

Configuration—Sets the polling rate for configuration-related information, such as VC tables, scrambling and so on. The default setting is 900 seconds (15 minutes).

•

System—Sets the polling rate for system-related information, such as network element name, network element location and so on. The default setting is 86,400 seconds (24 hours).

For information on adjusting the polling intervals, see Cisco Active Network Abstraction 4.0 User and Administration Guide on Cisco.com:

This section contains information on protocols used by the Network Resource Management components: Configuration Archive and Network Element Image Management (NEIM).

This describes the meaning of the certification levels found in the VNE support information tables in this Reference Guide.

Certification Level Legend	Certification Level Description
N	Not supported in ANA.
S	Support is available in ANA but not verified by the test team.
V	Verified by the test team.
