2.2.6.7 Running Inspection Tool

Context
It is recommended that you use SmartKit NSE2700 to comprehensively check the device after
upgrade. This will help you discover faults in time, ensuring device operation stability.

2.2.7 Version Rollback

Prerequisites
Before rolling V500R001C50 and later versions back to earlier versions, run the set system-
software check-mode all command in the system view. Directly roll other versions back to
earlier ones.
2.Before rolling back the original version, make sure that the corresponding configuration file
(already backed up before the upgrade) is loaded to the CF card of the device and is specified
as the file for next startup by running the startup saved-configuration cfg-filename command.
Then restart the device, avoiding configuration loss due to CLI differences between versions.
3.After V500R001C30 is upgraded to a version later than V500R001C50, PKI virtualization
is supported, and the storage directory of PKI certificate configuration file ca_config.ini is
changed from the root directory to the pki/public directory. When the current version is rolled
back to V500R001C30 and PKI service configurations are modified, the /pki/public/
ca_config.ini file needs to be deleted. Otherwise, the follow-up upgrade does not trigger the
upgrade of PKI services, and the PKI certificate configuration is lost after the upgrade.
7. In the hot standby scenario, during the version rollback from V500R001C80 and later
versions to V500R001C60 and earlier versions, SSL VPN users need to re-log in.
Application Scenario
The version rollback needs to be implemented if:
l
Issue 01 (2018-01-16)
Collect several tables and compare the tables with those before upgrade to check whether
certain entries are lost, including routing table, FIB table, MAC table, session table
entries, and whether service traffic amount after upgrade is approximately the same as
that before upgrade.
Contact the network administrator of the office and check whether the service is normal.
NOTICE
The device cannot start normally after upgrade, and the current version needs to be rolled
back to the previous one.
