Understanding the Image Version String
The image version string contains build information for each version of ExtremeWare. You can use
either the
show version or show switch command to display the ExtremeWare version running on
your switch.
Depending on the CLI command, the output is structured as follows:
• show version
Version <major>.<sub_major>.<minor> (Build<build>) {[branch | beta | tech |
patch]{<image_version>}.<image_description>-r<branch_revision>}
• show switch
<major>.<sub_major>.<minor>b<build>{[branch | beta | tech |
