IPX on same layer-2 vlan, but over 802.1q trunk

Our company is setting up a temporary IPX network for Novell. The clients will either be DOS IPX clients or Windows clients with gateway services. These clients will reside on Cisco-3550-switch-a. A Novell server will reside on Cisco- 3550-switch-b. There will be a fiber-obtic (802.1q) trunk connection between both server and client switch. Both environments will be on the same VLAN. I'll have to pass this VLAN info over the trunk.


Will the IPX communication pass over the Ethernet ports and hence over the trunk?


I heard enabling portfast helps.


Thanks,


Mike

Yes your IPX traffic should go across the trunk link.


Enabling portfast can help. We had a problem a long time ago with IPX where the client boots up and issues a GNS (Get Nearest Server) request. If portfast is not enabled then the GNS gets lost because the port is not forwarding the traffic.

As long as server and client are in the same VLAN it should pass traffic with no problem. If it were going to cross between VLANs then you would need to arrange for IPX routing. But within a VLAN it is just local traffic. At layer 2 there is not much different about an IPX frame.


I believe that portfast is very helpful for IPX devices.
