|  | 7.1 | The Basics of IOS Versions
| 7.1.3 | The show version command
The show version command displays information about the Cisco IOS software version that is currently running on the router. This includes the configuration register and the boot field setting (shown on the continuation of this example on the next page). In the example, the Cisco IOS version and descriptive information is highlighted on the second output line. The screen captured shows an experimental version of Release 11.2. The line System image file is "c4500-f-mz", booted via tftp from 171.69.1.129 shows the system image name. You will learn about Cisco IOS software Release 11.2 image naming conventions later in this lesson. For now, notice the portion of the filename that indicates that this image is for a Cisco 4500 platform. As it continues to output, the show version command displays information about the type of platform on which the version of Cisco IOS software is currently running. The highlighted text provides the results of the command config-register 0x10f, which is used to enter configuration register values. Note: You will not see evidence of any config-register setting in output from either the show running-config or show startup-config commands.
| Lab Activity
| In this lab you will gather information on the version of IOS software that is currently running on the router. You will also check the configuration register values to see where the router is currently configured to boot from.
