You to manage synchronization of images between management and interface modules in the
following situations:
•
When you are prompted to synchronize the images during the boot process.
•
When you want to initiate an immediate synchronization. For example, if you want an
immediate update of the images on one or all interface modules.
•
When you want to disable synchronization. For example, you have upgraded the image of one
interface module but want to continue running an older image on all other interface modules.
The following sections discuss how to manage the image synchronization in these situations.
Synchronizing interface module images during the boot process
By default, the router checks the images in the interface module flash memory during the boot
process to ensure they are the same as the images in the management module flash memory. If an
interface module does not have an image, the system automatically downloads the image from the
management module flash memory to the flash memory on the interface module.
If an interface module has different primary and secondary images than those of the management
module, the system prompts you to:
•
Replace the primary and secondary images in the interface module flash memory with the
images in the management module flash memory by entering the lp cont-boot sync
<
slot-num > command at the Privileged EXEC prompt.
•
Retain the images in the interface module flash memory, by entering the lp cont-boot no-sync
<
slot-num > command at the Privileged EXEC prompt.
Specifying an immediate synchronization
To immediately synchronize images between the management module and one or all interface
modules, enter the lp sync all command at the Privileged EXEC level.
Syntax: lp sync all | <slot-number>
•
The all keyword indicates that the immediate synchronization applies to all interface modules
in the router.
•
The <slot-number> parameter specifies the device slot number that contains the interface
module to which the immediate synchronization applies. You can specify 1 – 32, depending on
your router model.
Scheduling a system reload
In addition to reloading the router manually, you can configure the system to automatically reload
at a specific time, or after a specific amount of time has passed.
NOTE
The scheduled reload feature requires the system clock. You can use a Simple Network Time
Protocol (SNTP) server to set the clock or you can set the clock manually.
