Hello Everyone!
I'm very new to the Cisco environment and apologise in advance that this question has most likely been asked a hundred times before! I'm trying to configure the ACL for my Management network on VLAN 10 to have access to VLAN's 20, 30 & 40 servers. But the other users on their retrospective VLAN's can only access their specific sever.
I'm always trying to use the encapsulation command on the router for VLAN 10 but I keep getting the overlap error. And do I also need to use the encapsulation command for the other three VLAN's?
Can somebody please help me with this issue, I believe it maybe something to do with subnet masks (no doubt somebody here will know the very basic answer haha)
Thanks in advance

Hello
FYI - Your ip addressing was all incorrect, you were trying to create vlans and assign them addressing that overlap the /22 subnets you had created, Also you servers and end hosts had the incorrect gateways applied.
I have re-created a working topology based on your server and end host assignments, and created some ACL to filter intervlan traffic so ll the other vlans (other than mgt users) can just to access their own server.
Please review it so to see if it is much clearer for you to understand.
