Does MFF allow online users to retain online after the switch restarts


In V100R006 and later versions, when both MFF and DHCP snooping are enabled, you can use the dhcp snooping user-bind autosave file-name command to back up DHCP snooping binding entries in a specified file. This configuration allows online users to retain online after the switch restarts. Note that the backup file saves only the first gateway address of users.

Why is a user not displayed as Online on the RADIUS server after the user succeeds in S series switch authentication
In general, the RADIUS server identifies whether users are online by determining whether the accounting function is enabled rather than whether the user performs the authenticating operation. If a user succeeds in authentication but does not perform accounting, the RADIUS server considers that the user is offline. Therefore, check whether the accounting function is correctly enabled in the scenario where the accounting function is applied.
