LACP between Aruba MAS and Aruba 7210

  • 1.  LACP between Aruba MAS and Aruba 7210

    I must be missing something in my configuration. 

     

    I am trying to setup LACP between my backup controller and my Aruba switch stack. This will run over ethernet via the 1st and 2nd port (0/0/0 and 0/0/1) to ports on my switch stack (2/0/43 and 6/0/47)

     

    Whenever I setup the Port Channel/LACP on the controller I lose access to the controller. (Even when I add the ethernet ports on the switch to an LACP profile)

     

    The configuration on the controller looks like this:

     

    interface port-channel 1
    trusted
    trusted vlan 1-4094
    switchport mode trunk
    no spanning-tree

    interface gigabitethernet 0/0/0 description "LACP to Switch Stack" trusted trusted vlan 1-4094 lacp group 1 mode active interface gigabitethernet 0/0/1 description "LACP to Switch Stack" trusted trusted vlan 1-4094 lacp group 1 mode active

     

    On the Aruba Switch stack it looks like this:

     

    interface-profile lacp-profile "LACP_ToBackupController"
    group-id 3
    mode active

    interface gigabitethernet "2/0/43" description "LACP to BackupController" lldp-profile "lldp-factory-initial" lacp-profile "LACP_ToBackupController" interface gigabitethernet "6/0/47" description "LACP to BackupController" lldp-profile "lldp-factory-initial" lacp-profile "LACP_ToBackupController"

     

     

    What am I overlooking?

    What VLANs do you need to truck back to the controller including the management VLAN ?

    All Vlans Ideally, including Management yes. 

     

    The switch stack only contains Vlans used for user traffic.

    You need to configure it this way on both sides:
    Trusted
    Trusted VLAN <VLANs that you need>
    Switchport trunk allowed VLAN <VLANs that you need>
    switchport trunk native VLAN <Controller Mgmt VLAN>

    On the Aruba MAS you have to set trunking/vlan access via switching profile, however, in a LACP you cannot assign a switching profile to the port. How can I set the port to trust vlans? I don't see the option within the lacp group.

    Apply the switching profile under the port-channel
    interface port-channel "2"
    switching-profile "trunk-profile"

    Of course. I bet this is exactly it. Profile within Profile isn't something that comes to my mind first. I bet this will make it work.
