Switch Memory and Configuration
Using Primary and Secondary Flash Image Options
For example, if the switch is using a software version of G.01.01 stored in
Primary flash,
show version produces the following:

Determining Whether the Flash Images Are Different Versions. If the
flash image sizes in primary and secondary are the same, then in almost every
case, the primary and secondary images are identical. This command provides
a comparison of flash image sizes, plus the boot ROM version and from which
flash image the switch booted. For example, in the following case, the images
are different versions of the switch software and the switch is running on the
version stored in the secondary flash image:
The unequal code
size and differing
dates indicate two
different versions of
the software.
Figure 6-8. Example Showing Different Flash Image Versions
Determining Which Flash Image Versions Are Installed. The show ver­
sion command displays which software version the switch is currently running
and whether that version booted from primary or secondary flash. Thus, if the
switch booted from primary flash, you will see the version number of the
software image stored in primary flash, and if the switch booted from second­
ary flash, you will see the version number of the software version stored in
secondary flash. Thus, by using
show version, then rebooting the switch from
the opposite flash image and using show version again, you can determine the
version(s) of switch software in both flash sources. For example:
