Is there some function that can filter NetBEUI traffic through a
router/bridge based on packet size that can get set without user
intervention?  I have RSB (both simple and multi-port RSB show the same
symptoms) configured on a 7010/RSP w/ an old four-port CX Token interface
board.  I am bridging two switched TrCRFs from an Olicom 8600 (under
separate TrBRFs).  I am using Win2k NetBEUI clients (no IP).  When I do a
packet capture of a network browse/drive mapping session, I see lots of
traffic going through the bridge (using MS NetMon on either side of the
bridge, I see NetBIOS and LLC going back and forth), but none of my actions
are successful.  Browses and mappings do not complete.  The largest frame
that I can see traversing the bridge is 68 bytes.  Frames 102 or larger do
not make it through the bridge.  This is the only difference that I can see
between packets that make it through and those that don't.  The bridge MTU
is set to 4096 bytes.  There are no access lists set.  I have seen this
behavior on a 7007 also running a CX card.  I have no other multi-port token
systems to test it with.  Any help will be greatly appreciated.

Thank you,

Nelson R. Herron
