Hello everyone!
Today, I want to show you the restore configuration and data on the OLT. I have already described some of the procedures in previous articles:
Upgrade OLT - TFTP server for upgrade OLT (1)
Upgrade OLT – connecting PC and OLT (2)
OLT configuration backup procedure
Because of that, I will show you only the command for restore. Recovery is very important and useful, because we need to use it when we need to quickly return to the previous configuration or to make big changes to the configuration.
With the next command, we can start to restore configuration on the OLT:
TEST(config)#
TEST(config)#load configuration tftp X.X.0.45 TEST.CONF
{ Options<E><active,all> }: all
Command:
load configuration tftp X.X.0.45 TEST.CONF all
The new configuration file will overwrite the old one
Are you sure to load new configuration file? (y/n)[n]:y
Load(backup,duplicate,...) begins, please wait and notice the rate of progress Any operation such as reboot or switchover will cause failure and
unpredictable result
TEST(config)#
The loading starts
PARAMETERS :FrameID: 0, SlotID: 8, Position: -1, Load type: Configuration
file, Load Object: Active control board
TEST(config)#
The loading starts
PARAMETERS :FrameID: 0, SlotID: 9, Position: -1, Load type: Configuration
file, Load Object: Standby control board
TEST(config)#
Note: The configuration file in 0 frame 8 slot will take effect after being
activated
TEST(config)#
The loading is successful
PARAMETERS :FrameID: 0, SlotID: 8, Position: -1, Load type: Configuration
file, Load Object: Active control board
TEST(config)#
Note: The configuration file in 0 frame 9 slot will take effect after being
activated
TEST(config)#
The loading is successful
PARAMETERS :FrameID: 0, SlotID: 9, Position: -1, Load type: Configuration
file, Load Object: Standby control board
Then, the command to restore data on the OLT:
TEST(config)#load data tftp X.X.0.45 TEST all
Rollback function will be disabled after the database is loaded
Please reboot system in time to ensure that the loaded database takes effect
The database loaded separately will be invalid auto-
matically 24 hours later if you don't reboot system
Are you sure to load new database? (y/n)[n]:y
Load(backup,duplicate,...) begins, please wait and notice the rate of progress Any operation such as reboot or switchover will cause failure and
unpredictable result
TEST(config)#
The loading starts
PARAMETERS :FrameID: 0, SlotID: 8, Position: -1, Load type: Host data, Load
Object: Active control board
TEST(config)#
The loading starts
PARAMETERS :FrameID: 0, SlotID: 9, Position: -1, Load type: Host data, Load
Object: Standby control board
TEST(config)#
Note: the new file in 0 frame 8 slot will take effect after system is
restarted
TEST(config)#
The loading is successful
PARAMETERS :FrameID: 0, SlotID: 8, Position: -1, Load type: Host data, Load
Object: Active control board
TEST(config)#
Note: the new file in 0 frame 9 slot will take effect after system is
restarted
TEST(config)#
The loading is successful
PARAMETERS :FrameID: 0, SlotID: 9, Position: -1, Load type: Host data, Load
Object: Standby control board
And the end, we have to reboot OLT. We can do it with the next command:
TEST(config)# active configuration system
System will reboot after this command, continue? (y/n)[n]:y
TEST(config)#
TEST(config)#
