Overlapping VLANs? Tags: LAN Networking Last response: September 24, 2012 5:00 AM in Networking Share sdweim85 September 21, 2012 8:40:33 PM I'm working with a 3com baseline switch2948-sfp plus switch and I'm wondering if it is even possible to create overlapping VLANs. Its setup page just has untagged, tagged, and not a member selections. Certain departments only need to see 1 of the 4 fileservers to work from, but some of the management needs to see all 4 of them. Is it possible to have a setup like this Users are Ports 1-20 Servers are Ports 21-25 VLAN1 1,2,3,4 21, 25 VLAN2 5,6,7,8 22, 23, 25 VLAN3 9, 10, 21, 22, 23, 24, 25 VLAN4 11, 12 21, 24, 25 As you can see everyone needs server 25 and there is overlapping for the rest.

You would for example create 4 interfaces for server 25. Not a recommended design it tends to be pain to keep straight. The more common design is to place all the servers in a different vlan and then use rules to restrict the traffic. sdweim85 September 24, 2012 5:00:55 AM I will have to try that. Thanks There are only 4 servers actually. and 15 users so it it won't be confusing. Can't find your answer ? Ask !
