I am trying to add an extra VLAN (VLAN10, .10 subnet) to my 3560 and to get devices on the VLAN to acquire network information via an external DHCP Server and to also be able to the internet like devices on VLAN1.
Here is my problem with my current configuration:
1) DHCP on VLAN10 does not work meaning a device plugged into a port associated w/ VLAN10 will not get an address via DHCP. I have tried DHCP relay agent and I have configured the DHCP server w/ scope options for the VLAN10, .10 subnet. I have also configured option 82 and enabled dhcp snooping on the VLANs.
2) Devices on VLAN10 are unable to get to the internet while devices on VLAN1 can.
3) In order for my VLANs to communicate I have to change my GW (for devices on VLAN1) from the Router to the 3560. If not, then inter-vlan routing does not work. (Confused on why)
Anyways, with the GW changed to the 3560 for devices on VLAN1, they are able to ping devices on VLAN10 and vice versa. Devices on VLAN10 cannot ping the Router, but can ping the 3560.
Right now w/ the config that I have I don't know what else to do. Hopefully somebody can tell me what I am doing wrong.
No devices are connected to ports on VLAN10 at the moment, so VLAN10 isn't showing up in the routing table.
Here's my config:
