  • 1.  MacSec on LACP Trunk 2930M

    Posted Nov 11, 2020 10:31 AM
    Hi,

    does anybody know if MacSec on LACP is supported on any AOS Version. We have 2930m v16.10.0011 with 3810 MacSec/SFP+ Module but when trying to apply the MacSec policy we get a error:

    Cannot configure the MACsec policy on port %s when it is part of a trunk

    I did not find any information about not supported in combination with lacp and have the same running on e.g. Juniper Switches

    Hi! AFAIK on ArubaOS-Switch operating system based switch series the MACsec feature is mutually exclusive with trunking (lacp, trunk, dt-trunk, dt-lacp in HP ProVision/ArubaOS-Switch jargons).

    Hi all, with regard to this thread someone wrote me this in a PM (I can't answer via PM since it seems it doesn't work):

    "I could not understand your answer. Dose aruba 2930M switches with macsec module support lacp or not? In Aruba2930M / FAccessSecurityGuideforA OS-S16.10 it is listed that macsec does not support lacp"

    So here I give my explanation again:

    1. Aruba 2930M/F Switch series support "Port Trunking" (as known as Links Aggregation) with LACP, that's a well known supported features.
    2. Aruba 2930M Switch series support "MACSec" (on particular ports and models).

      What it is not supported is to use a "Port Trunk" logical interface (defined with either Non-Protocol or LACP) and apply a MACSec configuration to it, in other terms MACSec and Port Trunking are - considering a particular logical aggregated interface (with two or more physical member interfaces) - two mutually exclusive features. Given a physical interface you can configure MACSec or Port Trunking, not both (the physical interface can't also be member of a "Port Trunk").
