			8237-002/003 V1.34 Readme


The purpose of this release (V1.34) of code is to make a functional modification to the hub repeater code enabling proper operation when used in networks using multiple subnet masks.  It was found that in some cases, the 8237 was improperly filtering out valid packets based on its subnet mask.  If your network operated under one subnet mask, this change will have no effect.

IMPORTANT NOTE: This version of 8237 microcode supports both hub models 002 and 003. If there is more than 1 managing hub in a stack, both hubs must have their microcode updated to Version 1.31 or higher.  All Model 002 and 003 hubs in a stack must be at or above this level.  Failure to do this will result in a hang condition for the entire stack where, following a reset, the managing hubs will fail to negotiate their primary/backup assignments and no ID's will be assigned.
