Master Failover with Transparent Transition

The stacking feature supports a

or backup unit that assumes the

Master unit role if the Master unit in the stack fails. As soon as a Master

failure is detected in the stack, the Standby unit initializes the control plane

and enables all other stack units with the current configuration. The Standby

unit maintains a synchronized copy of the running configuration for the

The Nonstop Forwarding (NSF) feature 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 stack management unit. This type of operation is called nonstop

forwarding. When the management unit fails, only the switch ASICs on the

management unit need to be restarted.

You can add and remove units to and from the stack without cycling the

power. When you add a unit, the Stack Firmware Synchronization feature

automatically synchronizes the firmware version with the version running on

the stack master. The synchronization operation may result in either upgrade

or downgrade of firmware on the mismatched stack member.

You can configure rules to limit access to the switch management interface

based on criteria such as access type and source IP address of the

management host. You can also require the user to be authenticated locally or

by an external server, such as a RADIUS server.

For information about configuring access and authentication profiles, see

"Controlling Management Access" on page 169.
