Cisco WLC 5508 no traffic through wireless

Kevin100 · ‎09-25-2016

Hai

we have one customer with 5508 sso,

its connected to two edge switches then edge

connected to core all trunk ,core is the DHCP

server.The issue is clients can get ip

but no traffic pass outside gateway at core.

no error logged. Tested different switches same.

It was working before .

Entiire network works on LAN , no issues

anybody face similar issues

To be honest, we have seen this also:) What I would check is that nothing has really changed as in our case something did.

Verify that the interfaces on the WLC has the proper setting
Verify that spanning tree is forwarding the wireless user vlan out to the core
Verify that AP's are in the proper AP group and the group is defined correctly
Connect a laptop to a port in the same switch as the WLC that is on the wireless subnet and test

These are some things I typically verify first. The last bullet point will eliminate if the wireless is the issue or not.

You also didn't mention your setup, local mode or flex and what controller, controller version and AP's you have.

Well since it is only with Apple devices, post your show WLAN <WLAN ID> so we can see how your SSID is setup.

If you test with an open SSID, does the Apple device work? That will eliminate at least the controller and point to your other SSID
