Netgear M5300-28G-POE+ (GSM7228PSv1h2) - 12-Port Managed Gigabit Switch Softwarehandbuch

Use this command to prevent the chassis manager from downgrading the firmware version of 
a chassis member.

Use this command to display chassis firmware synchronization configuration status 
information.

Nonstop forwarding (NSF) is enabled by default on the chassis. You 
cannot disable NSF on the chassis.

A switch can be described in terms of three semi-independent functions called 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 determine how the forwarding plane should forward packets, deciding which 
data packets are allowed to be forwarded and where they should go. Application software on 
the management blade acts as the control plane. The management plane is application 
software running on the management blade that provides interfaces allowing a network 
administrator to configure and monitor the device. 

NSF allows the forwarding plane of chassis blades 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 blade. A nonstop forwarding failover can also be manually 
initiated using the initiate failover command. Traffic flows that enter and exit the
