MAC Address Changes
The MAC addresses in the system are based on the MAC address of the chassis. During switchover, the system's
MAC addresses do not change.
Management Module Redundancy Configuration
Configuring management module redundancy consists of performing one optional task (changing the default
active chassis slot). The section explains how to perform this task.
Changing the Default Active Chassis Slot
By default, the system considers the module installed in the lower-numbered slot to be the active management
module. If desired, you can change the default active chassis slot to the higher-numbered slot.
To change the default active chassis slot, enter commands such as the following:
FastIron# config t
FastIron(config)# set-active-mgmt mgmt1
Syntax:
[no] set-active-mgmt mgmt0 | mgmt1
mgmt0
is the lower-numbered slot and
mgmt1
is the higher-numbered slot.
To remove the configuration, use the
no
form of the command. You cannot use the
erase startup
command to
remove the configuration.
To view the default active chassis slot currently configured on the device, use the
show run
command.
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.
