    Is there a possibility to be informed if there are mac addresses dropped by the limitation.

    Hi!

    You can configure log event.
    More information in EXOS User Guide and Command Reference Guide.

    Thank you!

    It's not standard, isn't it? Because whether in the User Guide nor in the Refernce Guide I found a possiblity to be informed when mac-adresses are dropped because the limit-learning is reached and stop-learning takes place. The command "sh foobar sec" shows only "learned, blackholed and locked" but not dropped! And "sh fdb stats foobar" shows dropped mac-adresses, but not at which port of the switch. It would be great to see or to be informed at which port of the switch the macs are dropped because of limt-learning and action stop-learning. Any example or idea how this could work? Thank you in advance.

    Hi Jack,

    As Alexandr pointed out, we can also make this information automated so that it can show up in the log as below:

    Make the following configuration:

    configure log filter DefaultFilter add events FDB.FdbNotice

    * Slot-1 Stack.32 # sh log

    I agree with you when I configure:
    conf port 3:15 "foobar" limit-learning 1 action blackhole

    but with

    conf port 3:15 "foobar" limit-learning 1 action stop-learning
    you will not see the mac with "show fdb foobar"

    But this made my day:

    configure log filter DefaultFilter add events FDB.FdbNotice

    With this extension of the DefaultFilter you get:
