Overview
NOTE
This chapter applies to the FSX 800 and FSX 1600 chassis devices only.
You can install a redundant management module in the FSX 800 and FSX 1600 chassis. By default, the system considers the module
installed in the lower-numbered slot to be the active management module, and the module installed in the higher-numbered slot to be
the redundant or standby module. If the active module becomes unavailable, the standby module automatically takes over management
of the system.
This chapter describes the redundant management module, how it works with the active module, and how to configure and manage it.
This chapter provides the following information:
•
How management module redundancy works
•
Optional management module redundancy configurations that you can perform
•
How to manage and monitor the redundancy feature
NOTE
Hitless management features (hitless Layer 2 switchover and hitless Layer 2 OS upgrade) are discussed in the FastIron
Ethernet Switch Administration Guide.
How Management module redundancy works
This section explains the following:
•
How management module redundancy works under normal operating conditions.
•
Events that cause a standby management module to assume the role of the active module and how the switchover occurs as a
result of each event.
•
Implications that you should be aware of if a switchover occurs.
Management module redundancy overview
When you power on or reload a FSX 800 or FSX 1600 chassis with two management modules installed, by default, the management
module installed in the lower-numbered slot becomes the active module and the management module in the higher-numbered slot
becomes the standby module. (You can change the default active slot using the set-active-mgmt command. For information about
performing this task, refer to "Changing the default active chassis slot" section.)
After the active and standby modules are determined, both modules boot from the source specified for the active module. The active
management module boots from the active management module's flash memory.
