3259.0. "Autolearning on Repeater" by NETRIX::"robert.schmoelzer@grt.mts.dec.com" (NS Austria) Fri Feb 09 1996 14:07

Hello all,

Has anyone tried the Address Autolearning feature on the 900 repeaters.
I tried it on 900TM, 900TM and 900FP. None of these repeaters learned the
addresses of the connected station(s).

How I did it:
-click on the security icon for a specific port
-set intrusion mode to "Pass unauthorized packets"
-enable "learning"
-apply

after a refresh
-status of learning is "active"
-but no address appears in the "learned stations" window

any hints
robert

    Robert,
    
    I believe that there is a problem in the repeaters whereby they will
    not auto-learn an address on a port which it has  already seen on that
    port prior to enabling auto-address learning. So, if you have say one
    station off of a repeater port and that station's address has been seen
    by the repeater and then you enable auto-address learning, the address
    will not show up. If you had enabled auto-address learning prior to 
    connecting the station and/or before the station sent any messages the
    station's address would show up in the learned stations list, once the
    station was connected and it sent a message. This is combined with the
    fact that auto-address learning enable is a volatile setting. These 
    conditions makes this feature a lot less useful.
    
    With repeaters/ports that have activity from lots of stations this
    problem is not as obvious. With repeaters/port that only have a couple
    of stations it is very obvious.

3259.2no good messageNETRIX::"robert.schmoelzer@grt.mts.dec.com"NS AustriaMon Feb 12 1996 04:2210
This is obviously not a good message, since it makes this good feature not 
very useful. We have several customers who want to use this for security
reasons.

So, will this lack of functionality be changed in future version. Especially
to store the address database in a volatile portion of the ram?

regards
robert

3259.3it must be NONvolatile ramNETRIX::"robert.schmoelzer@grt.mts.dec.com"NS AustriaMon Feb 12 1996 04:338
It seems that the weekend was too long and the carneval makes me dizzy.

The database should be stored in a NONvolatile ram, of course.

hope i can see clear soon
robert
