SPECTRUM_5.0rev1.P49
After running Distributed Find across SpectroSERVER landscapes,
the chassis view of the SS6000 and SS9000 boards will not launch in
the landscape to which the user is connected. The problem is that
when the Distributed Find View is launched, it uses the landscape of
the server where the find is being done, instead of the landscape
where the SS9000/SS6000 device is actually modeled. The resolution
was to the use the model handle of the SS6000 and SS9000 as the
landscape handle.
ADISC does not discover SS6000 devices properly. The problem is that
all of the boards in the chassis do not know about each other across
the backplane. The reason is because of spanning tree. There are two
scenarios that exist that determine how spanning tree is implemented
across the backplane.
1. The root bridge is one of the boards inside the chassis. Spanning
tree sends BPDU's from the switches to the root bridge. If the root
bridge resides inside the chassis, then the BPDU's travel from the
other boards across the backplane to the root bridge and back. The
root bridge knows about all the other boards in the chassis and all
the other boards in the chassis know about the root bridge.
However, BPDU's are not passed between the other boards. Since
BPDU's are not passed between these boards, they "do not know
about each other" and their bridge tables are not compared.
The modeling in this scenario results in all the boards showing a
connection to the root bridge in a star.
2. The root bridge resides outside the chassis. Another bridge/switch
is connected via the front panel to a board in the chassis. The
BPDU's are sent across the backplane from the other boards in the
chassis out to the root bridge through the board which is
connected to the root bridge via the front panel. The front panel
board knows about all the other boards in the chassis because it
records the source mac from the BPDU's sent through it across the
backplane. However, none of the other boards know about each
other.
The modeling in this scenario is erratic at best.
