Switch Memory and Configuration

Multiple Configuration Files

Syntax: startup-default [ primary secondary ] config < filename >

Specifies a boot configuration policy option:

[ primary secondary ] config < filename >: Designates the startup-config file to use in a reboot with the software version stored in a specific flash location. Use this option to change the reboot policy for either primary or secondary flash, or both.

config < filename >: Designates the startup-config file to use for all reboots, regardless of the flash version used. Use this option when you want to automatically use the same startup-config file for all reboots, regardless of the flash source used.

For redundant management systems, this command affects both the active management module and the standby management module. The config file is copied immediately to the standby management module and becomes the default on that module when the next bootup occurs, unless redundancy is disabled or the standby module has failed selftest.

Note: To override the current reboot configuration policy for a single reboot instance, use the boot system flash command with the options described under “Overriding the Default Reboot Configuration Policy” on page 6-32.

For example, suppose:

■Software release “A” is stored in primary flash and a later software release is stored in secondary flash.

■The system operator is using memory slot 1 for a reliable, minimal configuration (named minconfig) for the software version in the primary flash, and slot 2 for a modified startup-config file (named newconfig) that includes untested changes for improved network operation with the software version in secondary flash.

The operator wants to ensure that in case of a need to reboot by pressing the Reset button, or if a power failure occurs, the switch will automatically reboot with the minimal startup-config file in memory slot 1. Since a reboot due to pressing the Reset button or to a power cycle always uses the software version in primary flash, the operator needs to configure the switch to always boot from primary flash with the startup-config file named minconfig (in memory slot 1). Also, whenever the switch boots from secondary flash, the operator also wants the startup-config named newconfig to be used. The following two commands configure the desired behavior.
