WLC 5508 tunneling issue

[Maurice Ball]

Hi,

I have a WLC 5508 connected in a hub and spoke topology. The WLC is located at the hub which is the main office. In one of the remote spoke locations I have five Access Points that are connected to the local LAN and the model for the APs is AIR-CAP3602I-E-K9. The APs are all connected to access ports on the switch in vlan 1. I have two WLAN configured on the controller. I have two interfaces configured on the controller. The management and the guest interface. WLAN 1 is associated with the management interface. In the WLAN 1 advanced setting the flex local switching option is enabled. WLAN 2 is associated with the guest interface and this interface is tunneling vlan 248 the guest vlan. The problem I am having is that the devices can not communicate with each other if they are connected to the wireless connection WLAN 2 which is the tunneled vlan.

Example: The client would like to be able to connect his ipad to the apple tv for presentation. If I connect both devices to the WLAN 1 which is using flex local switching option they can communicate with no problem, but if the devices are connected to WLAN 2 the guest vlan they can't communicate with each other. Is it possible to get this to also work on WLAN 2 ?

Note: Both WLAN types are WLAN and P2P Blocking Action is set to default (disabled).

Does any one have any ideas what could be causing my issue?

Thanks in advance for your help,

Well since your talking about Apple TV, you need to look at this reference guide for Apple's bonjour. This will explain how to get it to work and the limitation when an AP is in local or FlexConnect mode. The bonjour just doesn't work as people think it should because they can get it to work with a linksys AP.

You're my hero. Great information! One more question, once I configure the AP to use multicasting will they need to reboot for the new settings to take affect?

If your just enabling multicast then no. The only time an AP will reboot is when you change it's mode, you change it's AP Group or you manually reset the AP.
So enabling the basic requirements to get the bonjour stuff working will not affect your AP's.

thanks again

No problem.... Apple devices are very tricky to get working. Just make sure you have multiple ATS enabled on the wires side also.

Just in case you have concerns with bonjour when an AP is in FlexConnect mode rather than local mode, here is a good thread that Saravanan explains how it works in FlexConnect mode.
