ccna 200-125 cost.To better understand this, Figure 21-2 shows a conceptual view of the seven IOS images. Each image can be used for the same router model for the same software version/release. All images have the same base IP functionality. Some also have additional feature sets. Although this diagram shows only seven options to illustrate this point, the number of combinations in the diagram is much smaller than the number of real feature set combinations for a particular router modelQuantity.For example, suppose you want to use a specific security feature, which requires a security feature set. You can choose to purchase any of the 4 IOS imagesAny of the 4 IOS images, all of which contain a superior security feature set. If you do not need any of the advanced IP features or voice features, you can cancel the IOS image on the right because it contains the feature set.The IOS image on the right can be eliminated if you do not need any of the advanced IP features or voice features, as it contains a higher number of feature sets and is therefore more expensive.New I0S Packaging: Common Image Diagram for All Feature Sets 21.3 Common Image: One Image Supports All FeaturesCisco has started using I0S package models in a common image. The technical/am data language "universial image" means "all feature set". Basically, it replaces the old version of the model where each feature set was combined into a single image (as shown in Figure 21-2), and Cisco would build all feature sets into a single secure universal image. Each router model or model family will still have a different common image, just no longer a different image for different feature sets. IP Library428 Chapter 21 Managing IOS LicensesFor example, if a router supports IP library features, as well as voice, security, and an advanced IP feature set, Cisco generates a common image with all features for each router model/series and for each version/release. Figure 21-3 shows an example image that contains IP library, security, voice, data, and video features.21.2.2 Before using the Universal Image to activate the IOS software, Cisco allows everyone to download any IOS image for any Cisco router. This download process requires the user to agree to the terms of use. Nevertheless, anyone can obtain IOS images that can be used on actual Cisco devices.
