Overview of the Cisco WebEx Node for the Cisco ASR 1000 Series Routers
This chapter provides an overview of the release history, features, and MIB support for the Cisco WebEx Node on the Cisco
ASR 1000 Series Aggregation Services Routers. The Cisco WebEx Node is a shared port adapter (SPA) that provides enhanced performance
and reduced bandwidth consumption for WebEx web, VoIP, and video sessions in a large enterprise.
This chapter includes the following sections:
Release History
Release
Modification
Cisco IOS XE Release 3.11.0
The steps to configure the Cisco WebEx Node have been added.
Cisco IOS XE Release 3.8.0
The WebEx Node SPA supports Version T28.4 of WebEx. This version supports Cisco TelePresence WebEx OneTouch 2.0.
Cisco IOS XE Release 3.6.0
The WebEx Node SPA supports Version WBS27SP32 of WebEx. This version supports both high-quality and high-definition video
on the Audio and Video SPA.
Cisco IOS XE Release 2.4
Support for the Cisco WebEx Node was introduced on the Cisco ASR 1000 Series Aggregation Services Routers.
Overview of the Cisco WebEx Node SPA Environment
The Cisco WebEx Node is a SPA for the Cisco ASR 1000 Series Aggregation Services Routers that integrates transparently with
the Cisco WebEx collaboration cloud. The SPA runs WebEx software that enables the Cisco WebEx Node module to act like a private
extension of the WebEx service.
The Cisco WebEx Node for the Cisco ASR 1000 Series Aggregation Services Routers provides enhanced performance and reduced
bandwidth consumption for WebEx web, VoIP, and video sessions in a large enterprise. This is achieved by extending the hosted
Cisco WebEx collaboration cloud into a large enterprise by deploying primary software components of the WebEx platform to
an embedded processor within the onsite router.
The Cisco WebEx Node SPA is a full-height SPA that is designed to run an application that is a part of the Cisco WebEx Data
Center. The Cisco WebEx Node SPA improves the functionality of WebEx meeting services by adding the meeting servers into the
SPA itself. This technology provides the following advantages:
Improves performance for users inside the company firewall.
Reduces the bandwidth going out of the company firewall (to the WebEx Data Center).
Provides better security by reducing traffic outside the company firewall.
Software that runs on the Cisco WebEx Node for the Cisco ASR 1000 Series Aggregation Services Routers includes Cisco WebEx
collaboration cloud software components that are integral to meeting collaboration and voice and video conferencing. By moving
these components and functions into the Cisco WebEx Node SPA, the Cisco WebEx clients in the enterprise network have to connect
only to the Cisco WebEx Node SPA. This reduces the traffic between the enterprise network and the Cisco WebEx Data Center,
greatly reducing the customer’s internet bandwidth requirements.
By moving the switching components of the Cisco WebEx collaboration cloud into the Cisco WebEx Node for Cisco ASR 1000 Series
Aggregation Services Routers, the Cisco WebEx clients in the enterprise network have to connect only to the Cisco WebEx Node
SPA. This reduces the traffic between the enterprise network and the Cisco WebEx Data Center, greatly reducing the customer’s
internet bandwidth requirements, as shown in the following figure.
Instead of individual meeting streams from the Cisco WebEx Data Center to the enterprise, the use of the Cisco ASR 1000 Series
Aggregation Services Routers to implement some of the Cisco WebEx conferencing functions allows for a single meeting stream
from the Cisco WebEx Data Center to support enterprise conferencing traffic.
Figure 1. Cisco WebEx Network
Each Cisco WebEx Node SPA can be configured to perform either web conferencing or voice and video conferencing, but not both
at the same time. Each Cisco WebEx Node SPA uses the same software package that includes both features; but the conferencing
feature that actually runs on each SPA is determined by the Cisco WebEx Service Plan that the customer has purchased. The
WebEx Data Center retains the Cisco WebEx Node SPA configuration files that the SPA retrieves each time the SPA boots. Multiple
Cisco WebEx Node SPAs can be installed on the same Cisco ASR 1000 Series Aggregation Services Router to increase performance
or to provide coverage for both media and video or VoIP sessions.

Supported Features
The Cisco WebEx Node for the Cisco ASR 1000 Series Aggregation Services Routers includes basic features:
4-GB RAM
250-GB hard disk drive, with self-monitoring, analysis, and reporting technology (SMART) support for application data and
system log storage
Faceplate LEDs to indicate SPA status, hard disk drive activity, and system status
A Shutdown button to stop hard drive access activity before removing the SPA to prevent data corruption
Voltage and temperature monitoring
Online insertion and removal (OIR)
Downloadable configuration from the WebEx Data Center
Support for web conferencing or voice and video conferencing, and up to 500 clients for media or 600 streams for mixed audio
and multipoint video
Effective from Cisco IOS XE Release 3.6.0S, the Audio and Video SPA:
Supports HD video.
Collects QoS data, such as latency and jitter, for monitoring purposes. Note that the WebEx performance monitoring tools use
the QoS data present in the server trace logs for debugging purposes.
Tracks the quality of media controller servers. This is used to track the connections between the Audio and Video SPA and
the audio and video servers in the data center.
Effective from Cisco IOS XE Release 3.8.0S, the WebEx Node SPA supports Version T28.4 of WebEx. This version supports Cisco
TelePresence WebEx OneTouch 2.0.
Secure Sockets Layer (SSL) connection between the Cisco WebEx Node SPA and the WebEx Data Center, and secure connection between
the Cisco WebEx Node SPA and Cisco WebEx clients.
Monitoring the Cisco WebEx Node SPA from the Cisco WebEx Data Center.
Automatic recovery for service failures on a Cisco WebEx Node SPA by another Cisco WebEx Node SPA, or by the Cisco WebEx collaboration
cloud.
For detailed information about the hardware features and benefits of the Cisco WebEx Node for the Cisco ASR 1000 Series Aggregation
Services Routers, refer to the product data sheet at:
Performance can be affected if there is a slow connection to the WebEx Data Center because communication between different
Cisco WebEx Node SPAs has to go through the WebEx Data Center.
Before the Cisco WebEx Node SPA is removed, the software and the hard drive should be gracefully shut down, either using the
Shutdown button or the hw-module subslot stop command.
Either web conferencing or voice and video conferencing are supported, but both are not supported on the same Cisco WebEx
Node SPA.
The Cisco ASR 1002-X Router was introduced in Release 3.7.0S. This router does not support the Cisco WebEx Node SPA.
