    Hi,

    on a comware stack i'm seeing : 

    ...STP_DISPUTE: -Slot=2; Instance  0's port Ten-GigabitEthernet2/0/2 received an inferior BPDU from a designated port which is in forwarding or learning state.

    I do know where the issue is coming from.  The specific port is attached to an Aruba CX switch. And on this switch is networking equipment attached from an external vendor on port 10

    If i shut down this last port 10 the messages go away.

    Now i thought, if i set on the Aruba : 

    spanning-tree bpdu-filter

    on that port 10, i would get rid of the messages.  Unfortunately no...  The Aruba is running rpvst.  Limitation when running rpvst?  Do i need to switch to mspt?
