reboot rolling
This command reboots a stack in a rolling sequence to minimize downtime.
The stack master is rebooted, causing the remaining stack members to failover and elect a
new master. The rebooted unit remains separate from the remaining stack and boots up
as a stand-alone unit. Once the rebooted unit has finished running its configuration and
has brought its ports up, it reboots all the remaining stack members at once.
Syntax reboot rolling
Mode Privileged Exec
Usage If you are upgrading to a new software version, the new version must also support rollling
reboot.
Examples To rolling reboot the stack, use the following commands:
After running this command, the stack master will reboot immediately with the
configuration file settings. The remaining stack members will then reboot once the master
has finished re-configuring.

reload rolling
This command performs the same function as the reboot rolling command on page 83.4 .
Note When stacking is used with EPSR, the EPSR failovertime must be set to at least
5 seconds to avoid any broadcast storms during failover. Broadcast storms may
occur if the switch cannot failover quickly enough before the EPSR failovertime
expires. For further information about EPSR failovertime, see the
epsr
command on page 58.3 .
