Go to solution Solved by legopc,

Maybe you get duplicate addresses because you HAVE duplicate addresses... Your giving vlan 101 on ya cisco an ip of bla.1 and vlan 101 on ya edgemax an ip of bla.1 so yeah, thats duplicate. 

If you need help, just send me a message...

Maybe you get duplicate addresses because you HAVE duplicate addresses... Your giving vlan 101 on ya cisco an ip of bla.1 and vlan 101 on ya edgemax an ip of bla.1 so yeah, thats duplicate. 

If you need help, just send me a message... 

If you tell a big enough lie and tell it frequently enough it will be believed.
