Managing the interface modules

Configuring interface module boot parameters
The Ethernet interface module has its own system software and boots after the management
module boots. By default, the following boot-related events occur:
• The BigIron RX Series system synchronizes or prompts you to synchronize the interface
modules’ IronWare images between the management module and the interface modules.
• The interface modules boot from a source specified by the management module (the default
source is a primary IronWare image in the interface modules’ flash memory).
If desired, you can change the following:
• Disable the synchronization of IronWare images between the management and all interface
modules. You can also initiate an immediate synchronization.
• Change the boot source of one or all interface modules.
Synchronizing the interface module’s IronWare images
between management and interface modules
An interface module can have two IronWare images: primary and secondary. These images contain
the layer 1 – 3 software that the interface modules run. These images reside in the interface
module’s flash memory. Either the primary or secondary image is run by the interface module from
this location.
If you copy the primary or secondary IronWare image to all interface modules using the copy
command with the all keyword, the management module makes a copy of the file and stores it in
its code flash under the names lp-primary-0 or lp-secondary-0. The images are stored in this
location only and are not run by the management module or the interface modules. If you copy the
primary or secondary IronWare image to a specified chassis slot using the copy command with the
<chassis-slot-number> parameter, the management module does not make a copy of the file.
If the management module has a copy of the primary or secondary IronWare image in its code
flash, by default, the BigIron RX Series system synchronizes or prompts you to synchronize the
interface modules’ IronWare images between the management module and the interface modules
during bootup. When the BigIron RX Series system synchronizes the IronWare images, the
management module copies the IronWare images from its code flash to the interface modules’
code flash (the interface modules’ default boot source).
The system allows you to manage synchronization of the IronWare images between management
and interface modules in the following situations:
• You are prompted to synchronize the IronWare images during bootup.
• You want to initiate an immediate synchronization; for example, you want an immediate update
of the IronWare images on one or all interface modules.
• You want to disable synchronization; for example, you have upgraded the IronWare image of
one interface module but want to continue running the older image on all other interface
modules.
The following sections discuss how to manage the IronWare image synchronization in these
situations.
