You can use this command if you find that high error rate or abnormality occurs when the device uses
the current APR signature database for application recognition.
Each time a rollback operation is performed, the device backs up the current version of the APR
signature database. If you repeat the apr signature rollback last command multiple times, the APR
signature database will repeatedly switch between the current version and the last version.
To ensure that the APR signature database can be successfully rolled back to the last version, back
up the current APR signature database each time you update the database.
Examples
# Roll back the APR signature database to the last version.
<Sysname> system-view
[Sysname] apr signature rollback last
apr signature update
Use apr signature update to manually update the APR signature database.
