Managing interface modules

•
The verbose option generates logs whenever a temperature threshold is crossed. This is the
operational mode of previous versions of Multi-Service IronWare software and provides
backward compatibility.
•
The high option generates logs only when the high threshold is crossed.
•
The low option generates logs whenever any threshold (low, medium, medium-high or high) is
crossed.
•
The med option generates logs only when the medium, medium-high, and high thresholds are
crossed.
•
The med-high option generates logs only when the medium-high and high thresholds are
crossed. This is the default setting.
This output displays two instances of a module temperature exceeding the warning threshold.
Managing interface modules
Configuring interface module boot parameters
Ethernet interface modules contain independent copies of system software and boot after the
management module boots. By default, the following boot-related events occur:
•
The router synchronizes, or prompts you to synchronize, the software image on the interface
modules with the software on the management module.
•
Interface modules boot from a source specified by the management module (the default
source is a primary image in the flash memory on the interface module.)
You can make these changes:
•
Disable the synchronization of images between the management module and all interface
modules. You can also initiate an immediate synchronization.
•
Change the boot source of one or all interface modules.
Synchronizing the software image between
management modules and interface modules
An interface module can have primary and secondary images that reside in the flash memory.
If you copy the primary or secondary 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 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
image to a specified device slot using the copy command with the <
device-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 image in code flash, by default,
the router synchronizes, or prompts you to synchronize, images between the management module
and the interface modules during the boot process. When the router synchronizes the images, the
management module copies the images from flash memory to the flash memory on the interface
module (the default boot source for the interface modules).
You can manage synchronization of the software images between management and interface
modules in the following situations:
