You must make sure that there is enough free space in the flash before adding the file to the flash.It is important to know how to check how much free space is left in flash memory.A multimedia demonstration of viewing the contents of flash memory on a router is included in the digital resources that accompany this book.16.3.1 IOS Image Naming ConventionsCisco uses a naming convention for IOS images that lets you know what platform the image is for, what software version it is, and what features it contains based only on the file name. For example, see the image name displayed earlier by executing the command showflash on the router: c1841-advipservicesk9-mz. 124-6.T7.bino The following explains Cisco's IOS image naming convention.. C1841 refers to the platform the image is available for. This is important because different models of routers use different processors and an image compiled for one processor or router model will not usually run on other router models. Therefore, it is critical that the proper image be loaded on the device.. advipservicesk9 refers to the features included in that IOS image, often referred to as the feature set. In this example, the IOS image is advanced IPservices, where k9 indicates support for encryption.
