Setting Config_File Overwrite; Setting Config_File Synchronization - Cisco WS-C6506 Software Manual

Setting the Configuration Register

Setting CONFIG_FILE Overwrite

This command allows you to specify if the auto-config file should be used to overwrite the NVRAM
configuration or if the file configuration should be appended to what is currently in NVRAM.
Overwriting means that the NVRAM configuration will be cleared before executing the auto-config file;
appending means that the auto-config file will be executed without first clearing NVRAM. The default
is overwrite.
To specify if the auto-config file should be used to overwrite the NVRAM configuration or if the file
configuration should be appended to what is currently in NVRAM, perform this task in privileged mode:
Task
Specify if the auto-config file should be used to
overwrite the NVRAM configuration or if the file
configuration should be appended to what is
currently in NVRAM.
This example shows how to specify that the auto-config file is used to overwrite the NVRAM
configuration:
Console> (enable) set boot config-register auto-config overwrite
Configuration register is 0x12F
ignore-config: disabled
auto-config: recurring, overwrite, sync disabled
console baud: 9600
boot: image specified by the boot system commands
Console> (enable)
This example shows how to specify that the auto-config file is appended to what is currently in NVRAM:
Console> (enable) set boot config-register auto-config append
Configuration register is 0x12F
ignore-config: disabled
auto-config: recurring, append, sync disabled
console baud: 9600
boot: image specified by the boot system commands
Console> (enable)

Setting CONFIG_FILE Synchronization

The set boot config-register auto-config sync command allows you to enable synchronization to force
the auto-config file(s) to synchronize automatically to the standby supervisor engine. The file(s) are kept
consistent with what is on the active supervisor engine. The default is disabled. These events can trigger
a synchronization check and a synchronization (if necessary):
