Overview

Cisco Software-Defined AVC (SD-AVC) is a component of Cisco AVC. It operates as a centralized network service, with specific participating devices in a network.

Cisco SD-AVC complements solutions such as:

• Cisco Intelligent WAN (IWAN)

• Cisco EasyQoS

• Application Assurance

Some of the current features and benefits provided by SD-AVC:

• Network-level application recognition consistent across the network

• Improved application recognition in symmetric and asymmetric routing environments

• Improved first packet classification

• Protocol Pack update at the network level

• Secure browser-based dashboard over HTTPS

User Documentation

See the user guide for Cisco SD-AVC 1.1.0 at: https:/​/​www.cisco.com/​c/​en/​us/​td/​docs/​ios-xml/​ios/​avc/​sd-avc/​1-1-0/​ug/​sd-avc-1-1-0-ug.html

Requirements and Installation

SD-AVC consists of two main components:

• SD-AVC Network Service: Operates as a virtualized service within a Cisco device service container, hosted on a Cisco platform. A variety of Cisco ASR1000 Series, ISR4000 Series, and CSR100V models can function as the host platform for this component, which is installed using a downloaded OVA file.

• SD-AVC agent: SD-AVC can be activated on numerous devices in the network, which then communicate with the centralized SD-AVC Network Service. Activating SD-AVC on a device requires executing a few Cisco IOS commands on the device, and does not require any additional download. A variety of Cisco ASR1000 Series, ISR4000 Series, and CSR100V models are supported. Activating SD-AVC starts an SD-AVC "agent" service on the device, which manages communication between the device and the SD-AVC Network Service.

See the user guide for:

• System requirements for platforms hosting the SD-AVC Network Service, and instructions for installing the component, using an OVA.

• System requirements for devices running SD-AVC, and instructions for activating SD-AVC.

Supported Platforms

Host Platforms for SD-AVC Network Service

Downloading SD-AVC

The SD-AVC Network Service is installed from an open virtual appliance (OVA) file and operates as a virtualized service on a host platform. The OVA file is available for download on the Cisco.com software download page (http:/​/​www.cisco.com/​cisco/​software/​navigator.html). On the download page, specify a platform model to display software available for download. One software option will be SD-AVC.

Configuring the SD-AVC agent on network devices operating with the SD-AVC Network Service does not require downloading any additional software.

See the user guide for system requirements and installation instructions.

Example

To display the SD-AVC OVA file(s) available for the Cisco ASR 1002-HX platform, the navigation path is:

Products > Routers > Service Provider Edge Routers > ASR 1000 Series Aggregation Services Routers > ASR 1002-HX Router

SD-AVC Limitations

The following limitations apply to SD-AVC 1.1.0:

• For the SD-AVC controller, the host interface that is used as a gateway interface must not be attached to a VRF.

• Maximum number of devices running the SD-AVC agent: 20

• SD-AVC requires a few minutes to learn from the network traffic before the application data is sent to the controller and compiled at the network level.

• SD-AVC provides application classification for server-based applications, and partial classification for client-to-client traffic.

• In the case of a proxy or content delivery network (CDN), multiple applications may use the same IP/port combination. SD-AVC may reduce classification granularity of the applications sharing the same IP/port, or disregard that traffic. Nevertheless, individual devices continue to classify such traffic.
