Configuring Trunk Groups on AOS-S Switches in UI Groups

If you have AOS-S switches provisioned in an UI group, HPE Aruba Networking Central enables you to configure port trunking on these switches using the UI workflows. The network administrator can configure a trunk group on switches to create one logical link or a trunk by aggregating multiple links. The trunk link functions as a high-speed link to provide increased bandwidth.

A trunk group is a set of up to eight ports configured as members of the same port trunk.

      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.

  5. Click Save Settings.

If your AOS-S switches are running 16.10.0013 or later firmware versions:

  • You can remove the untagged VLAN from the trunk group at the group and device levels. At the group level, if you remove untagged VLAN from the devices running the firmware prior to the 16.10.0013 version, an event will be logged in the Audit Trail page stating that the untagged VLAN deletion is not supported.
  • You must either configure tagged VLAN or untagged VLAN as a mandatory parameter for the trunk group.
