Understanding the Image Version String

The image version string contains build information for each version of ExtremeXOS.

You can use the show version and show switch commands to display the ExtremeXOS version running on your switch. The output will be structured as one of the following:

• ExtremeXOS Version <major>.<minor>.<sustaining>.<build>

  In the case of a patch release, the version structure is ExtremeXOS Version <major>.<minor>.<sustaining>.<build>-patchX-Y where X is the patch type and Y is the build number for the patch.

• <major>.<minor>.<sustaining>.<build>patchX-Y

The following table describes the image version fields.

Image Version Fields Field Description major Specifies the ExtremeXOS major version number. minor Specifies the ExtremeXOS minor version number. sustaining Specifies the ExtremeXOS sustaining version number. build Specifies the ExtremeXOS build number. patch Identifies a specific patch 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.
