The user-manage user-trace table command sets a timeout period for formal and temporary user tracing entries.
The undo user-manage user-trace table command restores the default settings.
user-manage user-trace table { aging-time aging-time | pre-aging-time pre-aging-time }
undo user-manage user-trace table { aging-time | pre-aging-time }
| Parameter | Description | Value |
|---|---|---|
| aging-time | Specifies the timeout period of a formal user tracing entry. | The value is an integer ranging from 0 to 65535, in minutes. The value 0 indicates that an entry never times out. |
| pre-aging-time | Specifies the timeout period of a temporary user tracing entry. | The value is an integer ranging from 0 to 60, in minutes. The value 0 indicates that an entry never times out. |
By default, the timeout period of a formal user tracing entry is 1440 minutes, and the timeout period of a temporary user tracing entry is 3 minutes.
One or more FWs can be deployed on the wireless network egress. When a user who wants to access the Internet through a mobile phone is authenticated by the RADIUS server, the access device and RADIUS server start to exchange accounting packets. The deployed FWs can receive the accounting packets.
Each FW parses the accounting packets and allows the mobile phone user to go online. It creates a temporary entry whose default timeout period is 3 minutes.
After the temporary user tracing entry is updated to a formal user tracing entry, if the user does not initiate any service traffic or the FW does not receive any RADIUS accounting update packet within the timeout period of the entry, the user tracing entry to which the user corresponds will be deleted. When the user initiates service traffic again, the user needs to go online again from the FW.
When receiving service packets or RADIUS accounting update packets, the FW refreshes the remaining time of user tracing entries. In active/standby hot standby networking, the standby device refreshes the remaining time of user tracing entries only through RADIUS accounting update packets. Ensure that the timeout period of user tracing entries is greater than the interval for sending RADIUS accounting update packets, which prevents users from logging in and logging out frequently.
