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 ?
Thank you

All Vlans Ideally, including Management yes. 

 

The switch stack only contains Vlans used for user traffic. 

Re: LACP between Aruba MAS and Aruba 7210

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>

Thank you

Re: LACP between Aruba MAS and Aruba 7210

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. 

Re: LACP between Aruba MAS and Aruba 7210

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

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.
