Hello,
I have connected a PC runnin Netware 3.12 to a port of the
DECswitch900EF (V1.61). On the FDDI port there is a Novell
Server equipped with a DEFPA interface. When I try to login
from the PC it takes very long for the password to appear.
A program called syscon also takes very long to execute.
On the FDDI port of the bridge I can see many "oversized"
frames.
When I decrease a parameter called receive packet size on the
Novell server to 1500 I can login with no problem and the oversized
frames disappear.
In the readme file there is a reccomendation to have this parameter
at 4500 or above.
Could anyone please shed some light onto this ?

This recommendation is still valid. You should note that FDDI-sized
packets are up to 3 times larger than max Ethernet-sized packets.
Novell's client and server bits are *supposed* to negotiate the packet
size when one side (FDDI) can handle frames larger than the other
(Ethernet).
In practice, NetWare can handle this. Why it's not working in your
case is something to look into. I'd start by checking the client
configuration. Are you running the latest 16-bit client SW (VLM.EXE)
and the latest driver for your client?
