stack software-auto-synchronize
This command re-enables the software version auto-synchronization feature either on a
specified stack member or all stack members.
Use the no variant of this command to turn the software version auto synchronization
feature off.
Syntax stack {all|<stack-ID>} software-auto-synchronize
no stack {all|<stack-ID>} software-auto-synchronize
Default All the stack members have the stack software-auto-synchronize feature enabled by
default.
Mode Global Configuration
Usage This command is used to enable the software version auto-synchronization feature for
either a specific stack member or all stack members and candidates.
Note that if a device attempts to join a stack, but is running a software release that is
different to the other stack members, then the software version auto-synchronization
feature will copy the master's software release onto the new member. If the software
version auto-synchronization feature is not enabled, then the device will be unable to join
the stack.
Note that the software version auto-synchronization feature may also result in the stack
member downgrading its software release if the master is running an older software
version.
Examples To turn on the software-auto-synchronize feature on stack member 2, which was
previously turned off, use the following commands:
To turn on the software-auto-synchronize feature for all stack members, which were
previously turned off, use the following commands:
