You can reset the switch counters by using HUBwatch (I'll leave
the details on how to do this to others to explain).

Thanks for your answer Bob,
but I think, that's not the right answer I expected from a user of
notes, especially he/she is concerned with a theme.
Ok, thanks about the information how to reset a switch, but I don't
wanna physical reset, I'm looking for a methode to reset only the
counters, not the whole switch --> looking at Hyperhelp of HUBwatch:
" Resetting is the equivalent of turning power off ...". Do ya realy
think, that's the right way, terminate all the connection the bridge
have, wanna swap of the topology ( a little bit spanning tree )?
I hope, you haven'd meant this!!!
I think, I'm using notes not the first time, so I know some commands,
helping me to do my work somewhere in the suburbs of the widespread
networks. But not all the informations, being in someones brain, are
documentated here in the notes files, so why I don't ask some
questions, never asked befor??? Do you think you are knowing all
the problems somebody out in the field can have??? Then you are the
best!!! Sorry about, but I'm a little bit angry!!!
I only ask a little bit shy to some problems, I found out there in the
field, at first I do some searching in TIMA, Notes, my brain, asking
someone around me ( or using the telefon), and then I ask in a confe-
rence!!!
The request for some help is the same as mentioned in .0:
Something like "TEST Z" for the xxxSwitchxxx? ( Have do some network
analyzing at customer side, can't break FDDI-ring)
Novell-Server connected to a DECconcentrator 900 with FDDI_SNAP and
FDDI_802.2 enabled ( somewhere in *.CFG ), going to a xxxSwitchxxx
via backplane in a DEChub 900, can connect FDDI_SNAP to
Ethernet_802.3 ( Novell-Client ) but there is no connection via
FDDI_802.2 to Ethernet_802.2 possible.
Ok, I've no input from customer side about firmware of:
... hub ...
... switch ...
... HUBwatch ...
... and so on ...
Is it possible to answer such a question in a better way, that is
done before???

| Wolfgang, I'm not sure I see any reason to be angry, but I do
understand your frustration in your effort to assist your customer.
I also apologize if I misled you in any way or wasn't clear enough.
I'll try to clarify my response a bit here.
On the question of how to reset counters I had suggested using HUBwatch.
In some dyslexic fashion, I must have substituted your word reset with
the word read. You can *read* switch counters with HUBwatch, but you cannot
reset (or clear PE/DECswitch) counters dynamically using a management
tool such as HUBwatch. The only way to reset/clear PEswitch, DECswitch
counters is to reset the module (reset current settings) or power cycle
the unit. This was defined by the architecture to be the only way to
clear/reset counters. The reason being is that if there is more than one
network manager, and one manager arbitrarily reset/clears some counters,
it might be confusing to other people managing the same extended LAN.
This approach was also used in past bridge products as the best way
to minimize network management confusion. IE: The way to approach looking
at counters is to take periodic snapshots of the counters and subtract the
differences to obtain absolute values for a given period of time so as
to see trends in the rate of change of certain specific counter values.
On your second question on connectivity from a FDDI Novell-Server to
Novell-Clients, I have 2 questions.
1. Have you enabled the IPX switch on the PE/DECswitch?
(if your switches have the recently released wave-3 images, then you can
enable this via the switch console, in addition to enabling it from HUBwatch)
2. Are there any Ethernet v2 Clients on the Ethernet side of the Switches?
The same encapsulation should be used for all IPX end stations within an IPX
network. If the end stations are using raw 802.3 (Not recommended) and
the FDDI server is using SNAP, then it would work, *if* the IPX switch
on the PE/DECswitch is enabled.
