Stacking Commands 
46
M4200 and M4300 Series ProSAFE Managed Switches 
no boot auto-copy-sw allow-downgrade 
Use this command to prevent downgrading of the firmware version on the stack member if 
the firmware version on the manager is older than the firmware version on the member.
show auto-copy-sw (for stack firmware synchronization)
Use this command to display the stack firmware synchronization configuration status. 
Nonstop Forwarding Commands for Stack Configuration
You can describe a switch in terms of three semi-independent functions: the forwarding 
plane, the control plane, and the management plane. The forwarding plane forwards data 
packets. The forwarding plane is implemented in hardware. The control plane is the set of 
protocols that determines how the forwarding plane must forward packets, which data 
packets can be forwarded, and where the data packets must be forwarded to.
Application software on the management unit functions as the control plane. The 
management plane is also application software that runs on the management unit and that 
provides interfaces, allowing you to configure and monitor the device.
Nonstop forwarding (NSF) allows the forwarding plane of stack units to continue to forward 
packets while the control and management planes restart as a result of a power failure, 
hardware failure, or software fault on the management unit. 
You can also manually initiate a nonstop forwarding failover by issuing the initiate 
failover
 command. If the management unit fails, traffic flows that enter and exit the stack 
through physical ports on a unit other than the management unit continue with at most a 
subsecond interruption.
To prepare the backup management unit for a failover, applications on the management unit 
continuously checkpoint (that is, forward) information to the backup unit. Changes to the 
running configuration are automatically copied to the backup unit. MAC addresses stay the 
same across a nonstop forwarding failover so that neighbors do not need to relearn them.
