ProSafe Managed Switch
show stack-port diag
This command shows stacking diagnostics for each port and is only intended for Field
Application Engineers (FAEs) and developers. An FAE will advise on the necessity to run this
command and capture this information.
Non-Stop Forwarding Commands
Non-stop forwarding allows the stack units to continue to forward packets if the stack
management unit restarts because of a power failure, hardware failure, or software fault.
nsf
Use this command to enable nonstop forwarding feature on the stack. When nonstop
forwarding is enabled, if the management unit of a stack fails, the backup unit takes over as
the master without clearing the hardware tables of any of the surviving units. Data traffic
continues to be forwarded in hardware while the management functions initialize on the
backup unit. NSF is enabled by default on platforms that support it. The administrator can
disable NSF to redirect the CPU resources consumed by data checkpointing. If a unit that
does not support NSF is connected to the stack, then NSF is disabled on all stack members.
If a unit that does not support NSF is disconnected from the stack and all other units support
NSF, and NSF is administratively enabled, then NSF operation resumes.
