I made some test on VLAN, which were not really good.
Let's suppose that I have 2 switches, fully ~"busy"... all ports in full activity and with NO VLAN. One of the switch has the access to internet, via a router and modem.
Now, I would like that the port 9 from the two switches, accept a VLAN n# 2. That way, every incoming data, will be tagged with a VLAN 2... and will reach the other switch as VLAN 2. ( Like a Tunnel between the 2 "port 9"
My computer made a internet request on the port 9. Request has the VLAN2 ... goes to the 2nd switch tagged as VLAN 2...... and I have NO INTERNET ANYMORE !!!!!
- I've read that the reason would be that the router ( at the end of the chain , need to accept VLAN2 - Is that right ? )
What I want to do, is to create a VLAN in in order to avoid collisions on every packet going through the 2 switches ( like a tunnel ). But apparently, as soon as a device is using the VLAN2 tunnel, there is no possible communication.
( I also try to "Tick" the port 9 as VLAN1 and VLAN2, but no success ) If I select at the end VLAN1 and VLAN2 -> I should tag the frame as both VLAN 1 & 2 ? )
Thanks for your help
