Setting the user traffic backup threshold
About setting the user traffic backup threshold
The device backs up traffic for a user when the user's traffic reaches the user traffic backup threshold.
A smaller threshold provides more accurate backup for user traffic. However, when a large number of
users exist, a small threshold results in frequent user traffic backups, affecting the user online, offline,
and accounting processes. Set a proper threshold to balance between service performance and
traffic backup accuracy.
Procedure
To set the user traffic backup threshold:
Step
1.
Enter system view.
2.
Set the user traffic backup
threshold.
Logging out online portal users
This feature deletes users that have passed portal authentication and terminates ongoing portal
authentications.
When the number of online users exceeds 2000, executing the portal delete-user command takes a
few minutes. To ensure successful logout of online users, do not perform the following operations
during the command execution:
•
Active/standby MPU switchover.
•
Disabling portal authentication on the interface.
To log out online users:
Step
1.
Enter system view.
2.
Log out IPv4 online portal users.
3.
Log out IPv6 online portal users.
