I have 3 switches. Currently they're all setup at their default settings. I can access the web interface for all of them, and I've already identified which ports link them together, etc. I want to setup a few ports on one end that only has access to a few ports on the other end - but the other end will be the 3rd switch down the line. They're all linksys / cisco smart switches. I don't understand tagging and untagging properly I guess because as a test on one of the switches I tried putting the internet router and a workstation tagged to VLAN 25 (I had created that one as a test) but they are unable to ping each other. The devices on the ends of the switches are NOT VLAN aware. They're PC's and dumb routers. What's the best way to do this?
