We have a Cisco 3550 layer 3 switch with a couple of Vlans. The Vlan routing is enabled. We just started adding some Mac OS X laptops to our network and there is a Mac OS X server that is also a print server. Open Directory service is running on the server. The problem that I am experiencing is that Mac clients which are in the same subnet as the Mac Server can see the printers that are published by the server. However, the clients that are on a different subnet than the Mac Server can't see these printers. After some investigation I found out that I may have to allow Bonjour service to be heard in the other Vlans. I am very new to Mac administration and I do not know if there are other ways to do this. I would like to know how can I route the Bonjour service to the other Vlans? Would this tax the network performance?
