3717.0. "900TP autolearning" by HLFS00::BROUWERS_A () Wed Jul 17 1996 11:51

    900TP security autolearning doesn't work.
     
    A customer put his 900TP with version 2.1.0 on security enabled
    autolearning mode was on and no addres was detected on his port 
    also not after a refresh. He left this port on autolearning 
    several day's, but still no address.
     
    Now he's testing Version 2.1.1 with the same result.
     
    Can anybody tell me if it's working?

    Ad,
    
    	There is a problem in which the autolearning will not learn an 
        address which it already knows about. If autolearning was enabled
        on a port which has one station attached and that station's address
        had already been seen by the 900TP prior to enabling autolearning
        then I believe that the stations address will not show up. Perhaps
        one of the repeater folks could add more detail to this. I believe
        that once the address has been seen by the repeater, they no longer
        get a necessary interrupt for that address to be learned.
    
        What you could try (maybe) is to enable autolearning on the port in
        question and then attach another system to it. Then generate some
        traffic from that station and see if the address of the newly
        attached station shows up.
    
    Hope this helps,
    Bob

    Bop,
    
    testing it before your answer it reacts as you describes. If a station
    is already seen it will not be recognised by autolearning. In the port
    menu the address is shown but not in  the addres learned stations. What
    i did is: disconnect station, reset modulle with current settings. This
    keeps the old address authorisation, enable learning for all stations
    and then connect the stations. I was not able to test your suggestion.
    
    Customers will not like this, it means they almost always have to
    physical disconnect the station, enable autolearn, reset the module and
    physical connect the station. The only way to do this right is: enable
    autolearning on all ports BEFORE CONNECTING any station.
    
    This doesn't fit in the ID of remote networkcontrol. Any ID if this can
    be solved and when.
    
    
    Thank you helping me   Ad Brouwers.

    Ad,
    
    	I agree that this is not very useful in a real world environment.
        As for if/when anything will be done in this space I don't know.
    
    Regards,
    Bob
