NETGEAR 8800 User Manual Understanding the Image Version String The image version string contains build information for each version of XCM8800. You can use either the show version or show switch command to display the XCM8800 version running on your switch. Depending on the command line interface (CLI) command, the output is structured as follows: • show version XCM8800 Version ... For example: XCM8800 version 10.1.2.16 • show switch ... For example: 10.1.2.16 Table 77 describes the image version fields. Table 77. Image Version Fields Field major Description Specifies the XCM8800 major version number. minor patch Specifies the XCM8800 minor version number. Identifies a specific patch release. build Specifies the XCM8800 build number. This value is reset to 0 for each new major and minor release. The show version command also displays information about the firmware (BootROM) images running on the switch. For more information, see Displaying the BootROM and Firmware Versions on page 828. Software Signatures Each XCM8800 image contains a unique signature. The BootROM checks for signature compatibility and denies an incompatible software upgrade. In addition, the software checks both the installed BootROM and software and also denies an incompatible upgrade. Selecting a Primary or a Secondary Image A switch can store up to two core images: a primary and a secondary. When downloading a new image, you select which partition (primary or secondary) to install the new image. You must install the software image to the alternate partition, and must specify that partition before downloading the image. Appendix B. Software Upgrade and Boot Options | 803
