Configuring Loop Protection on AOS-S Ports

Loop protection provides protection against loops by transmitting loop protocol packets out of ports. For switches provisioned in UI groups, administrators can enable or disable loop protection on the switch ports or trunks. Loop protection is always disabled by default on AOS-S switches. For switch console access, non-administrators can configure a timer to auto-recover ports if the switch detects any loop.

To configure loop protection, complete the following steps:

  1. In the Aruba Central app, select one of the following options:
    • To select a switch group in the filter:
      1. Set the filter to a group containing at least one switch.

        The dashboard context for the group is displayed.

      2. Under Manage, click Devices > Switches.
      3. Click the AOS-S or Config icon to view the switch configuration dashboard.
    • To select a switch in the filter:
      1. Set the filter to Global or a group containing at least one switch.
      2. Under Manage, click Devices > Switches.

        A list of switches is displayed in the List view.

      3. Click a switch under Device Name.

        The dashboard context for the switch is displayed.

      4. Under Manage, click Device.

        The tabs to configure the switch is displayed.

  2. Click Interface > Loop Protection. The Loop Protection page is displayed.
  3. Depending on whether you want to configure a port or trunk, complete one of the following steps:
    • In the Port Settings tab, select the port(s), and click Edit.
    • In the Trunk Group Settings tab, select the trunk(s), and click Edit.
