How to configure communication between ACU2 and a switch

Hi everyone,

You all know what is an ACU2 and where it can be connected but I think it's useful to know how can we configure the communication between the ACU2 and the chassis where ACU2 is plugged.

As shown in Figure 1, ACU2 is installed in a chassis switch Switch_1. Interfaces XGE0/0/1 and XGE0/0/2 on ACU2 are connected to interfaces XGE1/0/1 and XGE1/0/2 on Switch_1 respectively. Switch_1 can be connected to an AP directly or through a network device, such as Switch_2 in this figure.

Switch_1 connects to ACU2 through interfaces XGE1/0/1 and XGE1/0/2. The first digit 1 in the interface number indicates the ID of the slot in which ACU2 is installed. XGE1/0/1 indicates that ACU2 is installed in slot 1 of Switch_1. If ACU2 is installed in slot 2 of Switch_1, it connects to ACU2 through interfaces XGE2/0/1 and XGE2/0/2.

XGE interfaces on ACU2 and Switch_1 that are connected need to be added to an Eth-Trunk to increase link bandwidth and reliability. If XGE0/0/1 and XGE0/0/2 are not added to an Eth-Trunk, only XGE0/0/1 can become Up but XGE0/0/2 is always Down.

Procedure

  • Configuring ACU2

    icon-note.gif NOTE:

    After completing the following steps, configure WLAN services according to WLAN Service Configuration Guide.

    1. Run:

      system-view

      The system view of ACU2 is displayed.

    2. Run:

      vlan vlan-id

      A VLAN is created and the VLAN view is displayed.

    3. Run:

      quit

      Return to the system view.

    4. Run:

      interface eth-trunk trunk-id

      An Eth-Trunk is created and the Eth-Trunk interface view is displayed.

    5. Run:

      port link-type trunk

      Attributes for the Eth-Trunk interface are configured.

    6. Run:

      port trunk allow-pass vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }

      Interfaces are added to a specified VLAN.

    7. Add XGE interfaces on ACU2 that are connected to the switch to an Eth-Trunk.

      icon-note.gif NOTE:

      When adding XGE interfaces to the same Eth-Trunk, retain the default configurations on the interfaces; otherwise, the interfaces cannot be added to the Eth-Trunk.

      • Add member interfaces to the Eth-Trunk in the Eth-Trunk interface view.

        Run:

        trunkport interface-type { interface-number1 [ to interface-number2 ] } &<1-8>

        Member interfaces are added to the Eth-Trunk.

      • Add member interfaces to the Eth-Trunk in the member interface view.

        1. Run:

          quit

          Return to the system view.

        2. Run:

          interface interface-type interface-number

          The interface view is displayed.

        3. Run:

          eth-trunk trunk-id

          The current interface is added to the Eth-Trunk.

  • Configuring a Switch

    icon-note.gif NOTE:

    The following configuration steps use a switch running V200R010C00 as an example.

    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      vlan vlan-id

      A VLAN is created and the VLAN view is displayed.

    3. Run:

      quit

      Return to the system view.

    4. Run:

      load-distribution mode slot slot-id enhanced

      The maximum forwarding capacity is configured for ACU2.

      slot-id specifies the slot number of ACU2.

    5. Run:

      interface eth-trunk trunk-id

      An Eth-Trunk is created and the Eth-Trunk interface view is displayed.

    6. Run:

      port link-type trunk

      Attributes for the Eth-Trunk interface are configured.

    7. Run:

      port trunk allow-pass vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }

      Interfaces are added to a specified VLAN.

    8. Add XGE interfaces on the switch that are connected to ACU2 to an Eth-Trunk.

      icon-note.gif NOTE:

      When adding XGE interfaces to the same Eth-Trunk, retain the default configurations on the interfaces; otherwise, the interfaces cannot be added to the Eth-Trunk.

      • Add member interfaces to the Eth-Trunk in the Eth-Trunk interface view.

        Run:

        trunkport interface-type { interface-number1 [ to interface-number2 ] } &<1-8>

        Member interfaces are added to the Eth-Trunk.

      • Add member interfaces to the Eth-Trunk in the member interface view.

        1. Run:

          quit

          Return to the system view.

        2. Run:

          interface interface-type interface-number

          The interface view is displayed.

        3. Run:

          eth-trunk trunk-id

          The current interface is added to the Eth-Trunk.
