Just as an aside for those of us using Cabletron FDMMIMs in our network(s),
verison 1.02.02 is available for the firmware that corrects a problem with
the bridge suddenly getting real stupid and apparently not working.  

The basic problem centers around the fact that in order to do translational
briding, the MIM has to disassemble the packet(s) for reassembly on the
other side.  If the packet disassembles as junk, the packet is reassembled, and
discarded.  However, in versions of the firmware up to 1.02, the buffer
(there are 32 of them) wasn't released for reuse, so, at some point, 
the FDDI ring seems to be out of service due to the cpu on the card running
out of buffers to use for legitimate packets.  

Solution is version 1.02.02 of the firmware, flash downloadable from
remote lanview or a tftp server.  Customer support in NH can provide...

Anyone else see this problem, or has it only been me????
