TABLE 13 Downgrade scenarios
Situation Result
The user never uses a write memory command when running
FastIron 08.0.90.
The downgrade is seamless.
The user does not change any configuration but uses the write
memory command when running FastIron 08.0.90.
The downgrade is fine. The system recovers the backup file before
reloading to a pre-08.0.90 release.
The user makes configuration changes while running FastIron 08.0.90
and uses the write memory command.
The downgrade loses all configuration changes made under FastIron
08.0.90. The system recovers the backup file that does not contain the
changes.
Switchover or failover does not affect these downgrade scenarios. For example, you may perform a switch-over to change the
active controller and then reload. The recovery result is the same as a reload without changing the active controller.
There are a few cases where recovery does not work.
TABLE 14 Scenarios where downgrades cannot be performed
Situation Result
The user reloads the system by powering down. The system cannot recover the backup file before reloading.
The standalone or active controller does not have a startup-config
flash file generated by any pre-08.0.90 release.
Downgrade is not possible.
NOTE
It is recommended that you copy the running configuration to a file before downgrading. You can do this using the copy
running-config command to copy the configuration to different locations such as a USB disk file or a tftp server, or you
can simply enter the show running-config command and then copy the output and paste it into a computer file.
NOTE
If you don't have a pre-08090-startup-backup file (which can be checked with the show pre-8090-startup-backup
command), or you have many configuration changes to the 08.0.90 release or a later release and you need to
downgrade to a pre-08.0.90 release, you must manually edit the 08.0.90 configuration to create a pre-08.0.90 format.
Stack interactive-setup
Stack interactive-setup is the recommended method for constructing a stack. The utility allows you to select units, IDs, and two-
unit linear-topology trunks. Stack interactive-setup replaces the stack secure-setup utility used in releases prior to FastIron
08.0.90. The stack interactive-setup command, entered in privileged EXEC mode, is used to initiate the utility and is available on
a standalone unit or on the active controller of a stack.
Stack interactive-setup has the following capabilities:
• Changing the ID for any existing unit, except for the active controller.
NOTE
Changing an ID does not result in a configuration change. For example, when users change a unit ID from 2 to
3, the system does not change any unit 2 configuration to unit 3 configuration.
• Discovering new links between existing units and enlarging the stacking port or stacking trunk. Stack interactive-setup
can discover new links between two end-units of a linear topology and convert the topology to a ring.
• Discovering clean units and converting them to stack members.
• Discovering existing standalone units and converting them to stack members.
