Changing the Getting Online Period in Loose Mode

Changing the Getting Online Period in Loose Mode

Getting online in loose mode after the system restarts due to an exception reduces client restarts, but may use a lot of resources. You can change the period during which users can get online in loose mode.

Prerequisites

Getting online triggered by IP/ARP packets has been enabled on a BAS interface.

Context

By default, the user information backup table cannot be queried within two hours after the NE40E restarts due to an exception, but original online users can still get online by using IP/ARP packets. You can run the access-trigger command to change the period during which users can get online in loose mode, avoiding users that get offline can get online again only after lease renewal fails (after the lease expires) or users' terminals restart. To change the getting online period in loose mode, perform the following steps on the NE40E:

Procedure

  • Configure user access in loose mode in the AAA view.
    1. Run system-view

      The system view is displayed.

    2. Run aaa

      The AAA view is displayed.

    3. Run access-trigger loose { loose-time | all-time }

      The period during which users can get online in loose mode after the system restarts is set.

      By default, users can get online in loose mode within 120 minutes after the system restarts.

      After this command is executed, the filtering function of the user information backup table does not take effect, and IP/ARP packets sent by users will trigger getting online requests. As a result, the NE40E needs to process a large number of getting online request packets, which uses a lot of resources and affects normal users' access.

      After the NE40E restarts, a large number of request packets will increase the pressure on the DHCP server and RADIUS server.

    4. Run access-trigger loose infinite-lease

      Users with an infinite lease are enabled to go online by sending IP/ARP packets when no abnormal logout backup entry is generated.

  • Configure user access in loose mode in the AAA domain view.
    1. Run system-view

      The system view is displayed.

    2. Run aaa

      The AAA view is displayed.

    3. Run domain domain-name

      The AAA domain view is displayed.

    4. Run access-trigger loose { loose-time | all-time }

      The period is configured, during which users in the authentication domain bound to the BAS interface can go online in loose mode after the system restarts. By default, users can go online in loose mode within 0 minutes after the system restarts.

      NOTE:

      If the period is configured both in the AAA view and AAA domain view, the configuration with a longer period takes effect.

    5. Run access-trigger loose infinite-lease

      Users with an infinite lease in the authentication domain bound to the BAS interface are enabled to go online by sending IP/ARP packets when no abnormal logout backup entry is generated.
