Software Upgrade Instructions
6.3 Changing between Multiple Versions of Software
It is possible to select between multiple versions of installed software at any
time (not just during an upgrade procedure). You can display all the versions
that are installed by typing the following:
localhost::operation flash> dir
FT330.35
CURRENT
FT340.11
However, in this list, CURRENT is simply a pointer to the version that will be
used as the current switch software AFTER a reboot. To display the version to
which CURRENT is pointing, as well as all the versions that are installed, type
the following:
localhost::operation> version
Software versions installed : FT330.35 FT340.11
Current software version is FT330.35
Notice that no parameter for version was specified above. If no parameter is
specified, it will list the current and installed versions, but will not change
anything.
In this example, to change the current version of software from FT330.35 to
FT340.11, type the following:
localhost::operation> version FT340.11
Current software version is FT340.11
Software versions installed : FT330.35 FT340.11
NOTE: By using the operation version command and
specifying a version, you change the version
to which CURRENT is pointing.
