I doubt that ipx broadcast-fastswitching will help you unless you are using an ipx helper-address. With ipx helper-address (just like ip helper-address) you can tell a router to forward a broadcast, which it normally doesn't do. This would be useful for some rare IPX application that sent broadcasts that needed to reach the other side of the router. In typical IPX networks, there's no such need. When there is a need, you can speed it up with the ipx broadcast-fastswitching command. You titled your message "10 half or 100 full." I think this was a Freudian slip. I bet your problem is related to a full-duplex mismatch. Perhaps the NICs in the NT servers negotiated correctly but the NICs in the Novell servers did not and you have a mismatch. With a mismatch, the full duplex side will send whenever it wants. The half duplex will get upset if it sees the other side sending while it is also sending and will backoff and retransmist, leaving behind a CRC-errored runt. That side will reports a collision. The other side will report runts and CRC errors. So, look for lots of Ethernet errors when you do a show int or show port. Also feel free to send us the output of various show commands and your router config. There are some IPX gurus on this list. _______________________________ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > > thanks > Mike > > Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=64935&t=64931 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
