•
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:
•
You are prompted to synchronize the software images during the boot process.
•
You want to initiate an immediate synchronization; for example, you want an immediate update of the software images on one
or all interface modules.
•
You want to disable synchronization; for example, you have upgraded the 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 software image synchronization in these situations.
