Filtering NT with a DB610
I have a customer who has a FDDi backbone-DB610 DeConn 500, who has now
installed a NT advance server with WFW 3.11. His concern is that the
NETBEUI is geting onto his backbone. He has difficulty filtering
out netbeui with a DB 90 (protocol filter), so he raised a issue that
as he cant use a DB90 to filter out the netbeui,, will his DB610 be
keeping his WFW users to their own workgroup( single floor ) of his
building.
Also is there a DB600 user guide on the network that I can get?
Thanks in advance
Steve

Depends. If the WFW users are all on the Ethernet side of the bridge,
then none of their unicast packets to eachother (NetBEUI or otherwise)
will go onto the FDDI ring. However, NetBEUI also uses multicast
packets with a destination address of 03-00-00-00-00-01. The bridge
will bridge these NetBEUI packets onto the FDDI because they are
multicast packets.

But of course, if Netbeui uses a specific multicast address, as you say, then the 610 (or the 900) can filter that. And if there's a protocol type or SAP address that identifies the traffic, you can filter on that too. paul | |||||
