ExtremeWare XOS 11.3 Concepts Guide

You can identify the appropriate image or module for your platform based on the filename of the
image. Table 71 lists the filename prefixes for each platform:
For example, if you have a BlackDiamond 8806 switch, download image filenames with the prefix
bd8800-. For additional installation requirements see the sections, “Installing a Core Image” on page 593
and “Installing a Modular Software Package” on page 594.
Understanding the Image Version String
The image version string contains build information for each version of ExtremeWare XOS. You can use
either the
show version or show switch command to display the ExtremeWare XOS version running
on your switch.
Depending on the command line interface (CLI) command, the output is structured as follows:
â—Ź show version
ExtremeW
are XOS V
ersion <major>.<minor>.<patch>.<build>
For example:
ExtremeWare XOS version 10.1.2.16
â—Ź show switch
<major>.<minor>.<patch>.<build>
For example:
10.1.2.16
Table 72 describes the image version fields.
Software Signatures
Each ExtremeWare XOS 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.
