302 | Configuration Replace and Rollback

Replacing the Current Running Configuration
Replace the current running configuration with an archived configuration using the command configure
replace from EXEC Privilege mode.
In the example below:
1. The hostname of the Dell Force10 system is changed from “R1” to “Force10.”
2. The running configuration is replaced with archive_0, in which the hostname is “R1.”
R1#config
R1(conf)#hostname Force10
FTOS#configure replace archive_0
This will apply all nessesary additions and deletions
to replace the current running-config with the contents
of the specified configuration file,
which is assumed to be complete configuration,
not a partial configuration
Please confirm if you want to proceed [yes/no]:yes
2d3h3m: %RPM0-P:CP %CLI-6-RBACKSTART: start rollback to file flash:/CFGARCH_DIR/
archive_0
2d3h3m: %RPM0-P:CP %SYS-5-CONFIG_LOAD: Loading configuration file
2d3h3m: %RPM0-P:CP %CLI-6-RBACKCOMPLETE: completed rollback to flash:/CFGARCH_DIR/
archive_0
R1#
Use the keyword force to bypass the FTOS confirmation dialog, as shown in the example below.
R1(conf)#hostname Force10
FTOS#exit
FTOS#configure replace archive_0 force
2d3h8m: %RPM0-P:CP %CLI-6-RBACKSTART: start rollback to file flash:/CFGARCH_DIR/
archive_0
2d3h8m: %RPM0-P:CP %SYS-5-CONFIG_LOAD: Loading configuration file
2d3h8m: %RPM0-P:CP %CLI-6-RBACKCOMPLETE: completed rollback to flash:/CFGARCH_DIR/
archive_0
R1#
Rolling Back to the Previous Configuration
FTOS allows you to implement an archived configuration for a specified amount of time, before reverting
to the previous running-configuration using the command
configure replace from EXEC Privilege mode;
FTOS requires you to enter the amount of time in seconds. This feature enables you to test a configuration
before committing the system to it.
• If you do not like the configuration, wait for the specified time to expire, as shown in the first example.
• If you like the configuration, enter the command
configure confirm from EXEC Privilege mode before
the specified time, as shown in the second example.
