Communication between 2 Vlans

[Beth_Dierks]

I am trying to get our wireless network communicating with a specific Vlan. So our wireless network is setup with a vlan as well. I have ipforwarding enabled for both vlans. What am I missing?

Just a little more information: If I am connected to the network via wired connection, I can ping a device on our 114 vlan. If I am connected to the network via wireless (118 vlan), then I cannot ping that same device.

Can you post the results of show vlan and show iproute from the core and the edge switches? You can sanitize the IPs as long as it's easy to tell the different subnets apart still and the logic stays accurate.

[Beth_Dierks]

Our wireless is configured for DHCP on both controllers and clients. On the Extreme side we do not have any ports that are configured just for the 118 Vlan.

It is strange because if on what we call our Finishing side, which has its own edge switch, we cannot ping the 114 vlan from wireless. However, if we are standing in certain areas on our Extrusion side, there are some areas that the wireless communication to the 114 vlan works and areas that don't.

When our main core was yet Cisco, everything worked as it should, even after we swapped out all Cisco edge switches with the edge Extreme. Now that we moved our main core over to Extreme, it does not. I am assuming it is configuration on the Extreme core but not sure what is missing.

I do not believe that it is configuration with the access points or the controllers.

Thoughts?

Thanks, Beth

Beth,

I would look at what information you have for subnet/routing at both the wireless controllers and on the wireless clients (DHCP config?).

Can you plug your laptop/device into a wired port on vlan 118, manually configure an ip/subnet/gateway that matches what the wireless clients should have and ping your VLAN 114 device?

[Beth_Dierks]

Our wireless controllers are Cisco 5508's
