First let me say, that i really like this community. It helped me a lot in configuring our Enterasys switches in my company. But now let me come to my problem.
We use a few 48 port poe swichtes in our AV Rental company. Its for connecting devices such as ethernet based intercom system and so on.
I configured the swichtes in 3 Vlans. Now i want to link the vlans between the switches. But i dont want to use a trunk port, i want to link them separately. It's because the Intercom uses full 1000 MBit if the max number of users is used.
I tried to link the two Vlans via sfp modules. The Sfp Ports are in the correct VLans. But whenever i connect more than one SFP Link between two switches the connection refuses and the devices cant talk to each other. I thought it could be something with a loopback. But the two SFP Port i connect to eacht other are in different Vlans. So there cant be a loop. or am i wrong?
I hope you can help me out with this. Just let me know, if you need additional information.
