Looking for some configuration tips on a couple of 3550 smi switches. I currently have production PLC and PC devices on the switches and am looking to segment them into 2 networks but they need to talk between a single server. I have been looking at Ciscos configurations and was wondering if anyone can tell me if I have to put an IP address at each interface or just the vlan them interface belongs to? Any other tips would be appreciated. since the switches are smi they only support static and rip routing? 1 switch is running Version 12.1(13)EA1a and the other is Version 12.1(12c)EA1. In total I have 6 of the 3550 on this lan but only need to segment and route between the 2. Thanks in advance.
