5 Managing interface modules • 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. Synchronizing the software image on interface modules during the boot process By default, the router checks the software images in the flash memory on interface modules during the boot process to see if they are the same as the images in the flash memory on the management module. If an interface module does not have a software image, the system automatically downloads the image from the management module to the interface module. If an interface module has an image that is different from that on the management module, the system prompts you to take one of the following steps: • To update the primary and secondary images on the interface module with the images on the management module, enter the lp cont-boot sync command at the Privileged EXEC prompt. • To retain the software images on the interface module, enter the lp cont-boot no-sync command at the Privileged EXEC prompt. Syntax: lp cont-boot sync Syntax: lp cont-boot no-sync Specifying an immediate synchronization To immediately synchronize software images between the management module and one or all interface modules, enter the following command at the Privileged EXEC level. PowerConnect# lp sync all Syntax: lp sync [all | ] • The all keyword indicates that the immediate synchronization applies to all interface modules in the router. • The parameter specifies the slot number that contains the interface module to which the immediate synchronization applies. You can specify 1 - 4 for 4-slot devices, 1 - 8 for 8-slot devices, or 1 - 16 for 16-slot devices. Specifying an immediate shutdown The management module takes approximately 16-20 seconds to shutdown all interface modules in a device after a reload is issued. During this time, the interface module continues sending packets. Enter the lp fast-powerdown command to immediately shut down all interface modules in a device after a reload is issued. PowerConnect(config)# lp fast-powerdown Syntax: [no] lp fast-powerdown If you do not enter this command, by default, the interface module continues to forward packets for an extended time after the router is reloaded. 114 PowerConnect B-MLXe Hardware Installation Guide 53-1002111-01
