Apr Signature Rollback - HP FlexNetwork MSR Series Command Reference Manual

Usage guidelines
This command starts the automatic APR signature database update process and backs up the
current APR signature file. This command is independent of the apr signature auto-update
command.
Use this command to update the APR signature database if you find a new version of APR signature
database at the Hewlett Packard Enterprise website.
Examples
# Manually trigger an automatic update for the APR signature database.
<Sysname> system-view
[Sysname] apr signature auto-update-now

apr signature rollback

Use apr signature rollback to roll back the APR signature database.
Syntax
apr signature rollback { factory | last }
Views
System view
Predefined user roles
network-admin
Parameters
factory: Rolls back the APR signature database to the factory version.
last: Rolls back the APR signature database to the last version.
Usage guidelines
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.
Syntax
apr signature update [ override-current ] file-path
