Communication between 2 Vlans

Communication between 2 Vlans

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.

It appears that the AP's are bridged back to the WLC and all the uplink ports are setup as tagged.

One item I did see in the iproute, is that Vlan300, which is what the AP's and WLC are on, is not listed in the iproute. Could this be the issue?

Is the VLAN tagged on all the uplink ports all the way back to the router? Like Doug says, Cisco uses VTP by default, which essentially configures everything for you as long as you designate the uplink as a trunk port. (Cisco VLAN naming standards are weird). The XOS switches will require manual VLAN tagging on all the uplink ports that connect back to the routing segment.

Well, my initial thought was maybe there's an issue with routing traffic back to the wireless clients.

Now I'm just going to ramble ideas and we'll see what happens.
Are there any LAG groups in the path wireless clients are taking? Perhaps there's an issue with traffic getting lost in the LAG? (This is usually diagnosable by looking at source/destination details and seeing that traffic works when the hash is even vs odd or visa versa and is usually caused by configuration mismatches between sides of the link)
Are all of the APs in the same mode (tunnel vs bridge)? Perhaps there's an issue there.
Do all of the APs in the extrusion switch have the same port configuration (VLANs, tagged/untagged)?
Are the wireless clients able to ping anything successfully? Their own gateway, switch and wifi controller management interfaces, etc?
Are they receiving an IP from DHCP that matches the scope you expect?

I know you said this all worked with a Cisco core, but Cisco also seems to support a lot of "auto configuration" when communicating with other Cisco products that the Extreme core likely doesn't support.

This edge switch has sporatic connections from the wireless to the 114 vlan:
