Managing management module redundancy
The
FSX 800
and
FSX 1600
support the following management tasks related to management
module redundancy:
•
Perform immediate synchronization of files
•
Perform a manual switchover to the standby module
•
Reboot the standby module
File synchronization between the active and standby management
modules
Each active and standby management module contains the following files that can be synchronized
between the two modules:
•
Flash code – The flash code can include the following files:
•
Primary – Contains the management module’s primary IronWare image.
•
Secondary – Contains the management module’s secondary IronWare image.
The primary and secondary files also include a monitor file, which contains the management
module’s Real Time Operating System (RTOS).
The IronWare image contains the layer 1 – 3 software run by the management module.
During startup or switchover, the active module automatically synchronizes the standby
module’s flash code with its own. Also, when you update the flash code on the active module,
the active module automatically synchronizes the standby module’s flash code with its own.
•
System-config file – The flash code also includes the system-config file. During startup or
switchover, the active module compares the standby module’s system-config file to its own. If
differences exist, the active module synchronizes the standby module’s system-config file with
its own. When you save changes to the system-config file on the active module, the active
module automatically synchronizes (without comparison) the standby module’s system-config
file with its own.
•
SSH and SSL keys
•
Flash file for the DHCP snooping feature
Each active and standby management module also includes boot code, which is the code a module
runs when it first starts up. The boot code resides in each module’s boot flash. The boot code is
synchronized between the two modules.
