10G LACP on 7024 with AOS 6.5.4.3

    Hello Guys,

     

    I'm facing an LACP issue with a 7024 controller and a Cisco switch on 10Gbit ports. 

     

    AOS = 6.5.4.3

     

    The problem is, that only one of the two ports in the Port-Channel gets up and running while the other one is suspended or waiting to be added to the channel.
    I've tried several configuration combinations and got always the same result:

    • aruba ports mode active | cisco ports mode active
    • aruba ports mode passive | cisco ports mode active
    • aruba ports mode active | cisco ports mode passive

     

    We've also swapped the SFP+ transceivers.

     

    Another thing i've recongnised is, that on the 7024 the "show lacp 1 neighbor" command shows only a sys-id on the working link and on the other one all zeros (00000000000). But if i run the same command on the cisco switch it shows the sys-id of the aruba controller on both interfaces of the channel. 

     

     

    Question: Is LACP supported with 10G interfaces? If so, has someone ever configured this and could provide me the interface config?

     

    ---------------------------------------------------------------------------------------

     

    Config 7024:                                                

    interface gigabitethernet 0/0/24

    description "GE0/0/24"
     trusted
     trusted vlan 1-4094
     lacp port-priority 200
     lacp group 1 mode active
    !

    interface gigabitethernet 0/0/25
     description "GE0/0/25"
     trusted
     trusted vlan 1-4094
     lacp group 1 mode active
    !
    !

    interface port-channel 1
     trusted
     trusted vlan 1-4094
     switchport mode trunk
     switchport trunk native vlan 99
     no spanning-tree

     

    Config on Cisco switch:                                                

     

    interface Te2/0/12
     switchport mode trunk

     channel-group 8 mode active

    !

    !

    interface Te2/0/13

     switchport mode trunk

     channel-group 8 mode active

    !

    !

    interface po8

     switchport mode trunk

     switchport trunk native vlan 99

     

    ---------------------------------------------------------------------------------------

     

    Thank you in advace

     

    Greetings

    See if these commands help:

    Aruba side
    nterface gigabitethernet <PORT NUMBER-1>
    trusted
    trusted vlan <VLANS>
    lacp timeout short
    lacp group <PORT-CHANNEL #> mode active
    !
    interface gigabitethernet <PORT NUMBER-2>
    trusted
    trusted vlan <VLANS>
    lacp timeout short
    lacp group <PORT-CHANNEL #> mode active
    !
    interface port-channel <PORT-CHANNEL #>
    trusted
    trusted vlan <VLANS>
    switchport mode trunk
    switchport trunk allowed vlan <VLANS>

    CIsco side

    Interface Port-channel <PORT-CHANNEL #>
    switchport trunk encapsulation dot1q
    switchport trunk allowed vlan <VLANS>
    switchport mode trunk
    switchport trunk native vlan <NATIVE VLAN>
    interface GigabitEthernet <PORT NUMBER-1>
    switchport trunk encapsulation dot1q
    switchport trunk allowed vlan <VLANS>
    switchport mode trunk
    channel-group <PORT-CHANNEL #>mode active
    interface GigabitEthernet <PORT NUMBER-2>
    switchport trunk encapsulation dot1q
    switchport trunk allowed vlan <VLANS>
    switchport mode trunk
    channel-group <PORT-CHANNEL #> mode active

    Hello Victor,

    Thank you for your response. :)

     

    I will for shure try the cmd "switchport trunk allowed vlan ...". 
    Althoug I've set it to "allow all" over the GUI.

     

    I set the lacp timeout to long for testing reason- I think short is the default value and I hadn't any luck with it.

    Also the encapsulation of the trunk on cisco side - dot1q is the default value on this IOS.

     

    Strange is that on of the two links is comming up and the other one not (in same Port-ch.)

     

    I will keep you up to date.
