In order to benefit from the MAPI application optimizer, you have to disable native Microsoft Exchange/Outlook encryption.

Cisco WAAS offers special protocol-level optimization for Windows Media Technologies over RTSP. For this kind of optimization, a separate WAAS license is required.

CIFS application support requires a separate WAAS license.

Cisco WAAS SSL optimization requires the core WAE to spoof the identity of the server, and therefore needs to have a local copy of the server certificate and private key.

Regional WAN: This used to be called Internet Edge and provides distributed Internet access.

Global CorE.This module interconnects multiple theater cores.

Enterprise CorE.This module interconnects all other modules.

In-Theater CorE.This module aggregates regional WANs.

CVD is technology-oriented, while SBA ismarket- and solution-oriented.

SBA guides are available for enterprise deployments only.

SBA is a blueprint for delivering the three Cisco architectures in a modular approach.

Gold partners have access to a demo lab for each validated design.

All three platforms support WIC, VWIC, and VIC.

NM and NME can be used in the ISR G2 via an adapter. NME-X is not supported on ISR G2.

All three platforms support AIM.

ISR and ISR G2 support PVDM2; noadapter is required in ISR G2.

The technical solution has to be based on the previously defined architecture.

Examples of low-level design tools are the Cisco Power Calculator, the Cisco Rack Space Calculator, and the Cisco DSP Calculator.

CVDs provide proven design of solutions that include only Cisco products, which ensures single-vendor solutions.

Numerous CVDs are available that provide all the information needed for a successful deployment.

The SBA toolkit includes foundation design guides that focus on concepts as well as foundation design guides that show detailed configurations.

The Cisco Prime user interface is optimized for touchscreens.

All components of the Cisco Prime for Enterprise product portfolio provide a common look and feel, which simplifies usability.

Integrated workflows and best practices enable quick and error-free deployment.

TrustSec, MediaNet, and EnergyWise services are only configured outside Work Centers in Cisco Prime LMS.

A universal Cisco IOS image includes all software features; additional software features are then activated by license keys without changing Cisco IOS.

In order to obtain a license file, the product ID and serial number of the device are sent to the representative Cisco Channel Partner, along with the purchased product activation key.

Cisco IOS 15 is available in two trains: T, which includes bug fixes and new features, and M,which includes bug fixes only.

The Cisco ASR 1000 series features IOS-XE, a software architecture that consists of a platform component, IOS-XE middleware, andthe actual Cisco IOS software.

Cisco WAAS can substantially reduce band requirements of Microsoft RDP, Citrix ICA, and PCoIP.

When using Microsoft RDP, make sure that you disable nativeRDP compression and encryption.

When testing or demonstrating WAAS performance with ICA, be aware that the bandwidth reduction increases with additional users. Traffic of a single user is reduced by 20 – 30%, while traffic of 10 users is reduced by 50 – 70%.

Cisco WAAS can provide about 20% compression ratio for watching videos over Microsoft RDP.
