I would like to share my Network diagram with you. I have seven WS-C2960-24TT-L switches and oneWS-C3560G-24TS. I would like to create the VLans for 12 Department. and I have Firewall also. We are using Micorsoft Exchange server, DHCP, DNS and Active Directory. So I would like to create the VLANs for server network. But I would get the ip address for different Vlan from DHCP server.How should l configure in Layer 3 switch. and Is there any problem with Microsoft DNS server to update DHCP IP and DNS name? I would like to get the advice from you for best design..Really thanks if you help me about it..if you would like to get Network Diagram. I am welcome to give you.My main purpose..I would like to get the sutiable and best network design for my Network...
you probably have a default static pointing to FW for your internet . Unless the FW has a route pointing back it has no idea what to do with the packets for those subnets coming back .
You would have to check the FW to see if ping response is even allowed , in most cases FW's block ping .
No you should not need to put an address on port 24 , it is assigned to vlan 1 so that should suffice . You say you cant get to the internet . I assume there is a FW between you and the internet does that device have routes in its table for all the vlans you created that you want to get to the internet . It needs a path back into the 3560 to be routed correctly.
