  • 1.  Aruba 2930F: Error when trying to set lacp trunk as vsf link

    Dear Aruba experts,

    I failed setting up a VSF configuration and thus seek your help!

    I do have 2x ARUBA 2930F JL254A and 1x ARUBA 2930F JL262A available.
    All three switches run the same and latest firmware version 16.11.0020.

    The JL254A has 48G and 4SFP+ ports and the JL262A has 48G PoE+ and 4SFP ('non-plus') ports.

    Prior to setting up Port-based VLANs, I want to form a VSF stack of all three switches with ring-like connection.

    Since some SFP+ ports are required for server connection, I do not have all SFP+ / SFP ports available for use as VSF links.
    And since the JL262A does not have SFP+ but only SFP ports, I can make and have to make use of some of the RJ45 ports, anyway.

    I attached a picture file showing how I thought of establishing VSF links and later assign Port-based VLANs.

    I created the LAG trunks for the RJ45 ports as follows:

    Switch #1: trunk 45-48 trk11 lacp

    Switch #2: trunk 45-48 trk22 lacp

    Switch #3: trunk 41-44 trk31 lacp   and   trunk 45-48 trk32 lacp

    Now I made sure that all ports, which shall be set as VSF links, are disconnected and then started setting up VSF by using the commands as follows for switch #1:

    vsf member 1 priority 200
    vsf member 1 link 1 49
    vsf member 1 link 2 trk11
    vsf enable domain 1

    However, as soon as I want to assign such a trunk port as VSF link, I get the error message   Module not present for port or invalid port: trk11

    I have no idea, what this means and could not find any solution. Can someone please help me out?

    I got this error for all three switches as soon as I try to set such an lacp trunk port as VSF link. "Normal" ports do work.

    I removed all VSF-related settings again, and reconnected the cables (we STP enabled) again.

    Currently, a   show lacp  returns me this:

               LACP      Trunk     Port                LACP      Admin   Oper
       Port    Enabled   Group     Status    Partner   Status    Key     Key
       -----   -------   -------   -------   -------   -------   ------  ------
       45      Active    Trk11     Up        Yes       Success   0       542
       46      Active    Trk11     Up        Yes       Success   0       542
       47      Active    Trk11     Up        Yes       Success   0       542
       48      Active    Trk11     Up        Yes       Success   0       542

    A   show trunk   returns me this:

    Load Balancing Method:  L3-based (default)

      Port   | Name                             Type       | Group Type
      ------ + -------------------------------- ---------- + ----- --------
      45     |                                  100/1000T  | Trk11 LACP
      46     |                                  100/1000T  | Trk11 LACP
      47     |                                  100/1000T  | Trk11 LACP
      48     |                                  100/1000T  | Trk11 LACP

    Thank you very much in advance for your help!

    Hi Enrico, the error is that VSF Links should be created (also by "aggregating" more that one port) with commands like these (VSF Switch 1 - say it is the VSF Commander, example):

    vsf member 1 link 1 45
    vsf member 1 link 1 46
    vsf member 1 link 1 47
    vsf member 1 link 1 48

    and not pre-imposing a logical interface Trk<id> made of ports 45, 46, 47 and 48 (with LACP).

    That's because the VSF will manages the above (four) ports as the VSF Link 1 on the VSF Switch 1 and so on with the others.

    In other words: "Configure a VSF link, a minimum of one physical interface should be bound to the link. The bound physical interfaces are automatically aggregated to form a VSF link.".

    See here.

    Edit: forgot to link the old (but always useful) Backplane Stacking and VSF Best Practices for ArubaOS-Switch (16.08) here.
