User Guidelines
The configuration on the stack master switch controls the stack as if it is a
single switch. A stack member with a different version of firmware is not
allowed to join the stack. No configuration steps need to be taken on the
member switches to downgrade the firmware version. Configuration
migration during a downgrade is not assured. The operator should ensure that
the configuration can be downgraded before allowing the downgrade to occur
or otherwise take steps to reconfigure the switches.
Downgrade of the firmware version is also supported for firmware images
discovered during DHCP provisioning or during the Auto-Install process. If
this command is enabled and a downgrade version of firmware is found, the
stack master will downgrade itself and all stack members.
During a downgrade, meta-data regarding the stack configuration is not
migrated. For example, Ethernet ports configured as stacking ports will revert
to the default Ethernet configuration during a downgrade. When this occurs,
the stack will be split into individual switches, each of which must have the
relevant Ethernet ports individually configured as stacking before the stack
can be reconstituted.
boot host auto-reboot
Use the boot host auto-reboot command in Global Configuration mode to
enable rebooting the device with no administrative intervention when a new
firmware version is successfully downloaded using the Auto-Install process.
Use the no form of this command to disable rebooting the device. Auto-
install successfully downloads a new firmware version.
