    HPE Bridge aggregation (BAGG) is method of combining multiple physical connection into one single virtual interface increase the throughput.

    To Create Bridge aggregation (BAGG) following steps need to be considered

    1.Create a  Bridge aggregation interface , by default it takes static aggregation group

    [5900]interface Bridge-Aggregation 10

    [5900-Bridge-Aggregation10] link-aggregation mode dynamic

    2. We need associate the interfaces which needed to be part of BAGG . Once you associated the physical interface, you need to make changes only on bridge aggregation interface

    [5900]interface GigabitEthernet1/0/48

    [5900-GigabitEthernet1/0/48]port link-aggregation group 10

    [5900]interface GigabitEthernet1/0/49

    [5900-GigabitEthernet1/0/49port link-aggregation group 10

    3.Pass the vlan on BAGG interface

    [5900]interface Bridge-Aggregation 10

    [5900-Bridge-Aggregation10]port link-type trunk

    [5900-Bridge-Aggregation10]port trunk permit vlan

    To verify the BAGG / Link-aggregation,

      ===============display link-aggregation summary=============== 

    Aggregation Interface Type:

    BAGG -- Bridge-Aggregation, RAGG -- Route-Aggregation

    Aggregation Mode: S -- Static, D -- Dynamic

    Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing

    Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing

    Flags:  A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation,

                D -- Synchronization, E -- Collecting, F -- Distributing,   G -- Defaulted, H – Expired


    Aggregate Interface: Bridge-Aggregation10

    Aggregation Mode: Dynamic

    Loadsharing Type: Shar

    System ID: 0x8000, bdca-cha6-4d38



      Port             Status  Priority Oper-Key  Flag


      XGE1/0/48        S       32768    2         {ACDEF}

      XGE1/0/49        S       32768    2         {ACDEF}



      Actor            Partner Priority Oper-Key  SystemID               Flag  


      XGE1/0/48       68      32768    2         0x8000, bdca-cha6-23c1  {ACDEF}

      XGE1/0/49         3       32768    2         0x8000, bdca-cha6-23c1  {ACDEF}

    For successful bridge-aggregation the flags ACDEF must match with remote interface.

    Like the briding L2 LAG (BAGG) you can also create route L3 LAG (RAGG).

    The platform must support it though.

    I believe it is supported from 55nn platform where you have full L3 switches.

    Also supported on router platforms.

    Here is a an example of the logical interface for the RAGG with a sub interface tagged with VLAN 4 as well as the physical port members. It is from 5940 Comware 7 platform.

    interface Route-Aggregation33
    description VPNC1
    link-aggregation mode dynamic
    interface Route-Aggregation33.4
    ip address
    ospf network-type p2p
    interface Ten-GigabitEthernet1/0/33
    port link-mode route
    port link-aggregation group 33
    <dksw01>disp cur interface ten 3/0/33
    interface Ten-GigabitEthernet3/0/33
    port link-mode route
    port link-aggregation group 33
