3210.0. "port not switchable to thin wire" by HLFS00::BROUWERS_A () Mon Jan 29 1996 10:45

    DECswitch900CP Port switching matrix "V" sometimes gone
    
    after clicking a port on f.i group 2 it is not possible to click it
    back on group 1.  It looks like it happens in an Hub without a Bridge
    in it.  The sw version is V2.1.0

3210.1might wanna try this....NETCAD::GORDONWed Jan 31 1996 12:2711
    Some Help ???
    We've (system test) have found this recently. Here's a quick thing to
    try. On the ports that were moved to another group, you now want to 
    put them back on the top group. Ie: group with MAC ?
    Try putting a repeater terminator on the port your trying to move back
    and that should let you move the checkmark back up to the top group.
    
    BTW: Are your checkmarks vanishing when you try to get back to group 1??

    As a follow-up on .0:
    
    In-house we did put a terminator on the port as you suggested and that
    works!! However: on the customer site there was a terminated piece of
    cable including two stations connected to that same port; which makes
    the whole thing a bit suspicious.
    
    btw. Yes the checkmarks are gone and only be regained by resetting the
    whole repeatermodule. From what we see is that the 'unterminated' port
    comes into a 'management disabled' state and possibly due the
    autopartition mechanisme never is able to return to the 'normal' state.
    
    So if live-ports can not be switched then the switch gets more or less
    unusable for some customer situations.
    Will this be solved? And if so when can we/customer expect the release?
