issu rollback-timer
Syntax
issu rollback-timer minutes
undo issu rollback-timer
View
System view
Default level
2: System level
Parameters
minutes : Rollback timer value in minutes, ranging from 0 to 120. A value of 0 indicates that the version
rollback function is disabled and the rollback timer is not created when you execute the issu load
command.
Description
Use the issu rollback-timer command to set the rollback timer value.
Use the undo issu rollback-timer command to restore the default.
By default, the rollback timer value is 45 minutes.
NOTE:
With the issu load command executed, the system automatically creates a version rollback timer. If you
do not execute the issu accept or issu commit command before the specified rollback timer expires, the
system automatically stops the ISSU process and reverts to the previous software version.
You may need to use the version rollback function in some cases, for example, when the new system
software image is broken.
If you execute the issu rollback-timer command during an ISSU upgrade process, the rollback timer
takes effect for the next ISSU upgrade process.
Examples
# Set the rollback timer value to 30 minutes.
<Sysname> system-view
[Sysname] issu rollback-timer 30
