Wireless Multicast on WLC 5508 release 7.5

Hi, i'm working with WLC 5508 with about 60 Lightweight APs, I want to use an application on the Laptops connected to Wireless network via Multicast. Multicast is working fine in the wired network, but I need to work with the application in Wireless network also.

The configuration of Multicast on WLC is set as following:

Controller > AP Multicast mode: Multicast, IP:

Controller > Multicast: Enable global multicast mode is check, also the IGMP snooping

Wireless > Media Stream: Multicast direct feature is NOT enabled

The WLC is recognizing the Multicast groups (,, and so on).

The SSIDs not have enabled Multicast Vlan Feature, but I did enabled it to make tries but isn't working.

WLC sees the device directly connected via CDP (Switch 4510) but it see it with the IP address belonging to Interface Vlan 1 on 4510 switch, but the Vlan belonging to WLC is Vlan 98 and has an IP address of, I don't know if it may cause some problems.

Here is also the configuration on switch 4510 corresponding to WLC:

interface TenGigabitEthernet5/1

description TO WLC

switchport mode trunk

interface Vlan98

description VLAN AP_WLC

ip address

ip helper-address

ip directed-broadcast

ip pim sparse-dense-mode

ip route-cache same-interface

no ip split-horizon

I appreciate your help with this issue. Thank you.

Wireless Multicast on WLC 5508 release 7.5

If your multicast application required bandwidth (like video stream) then you SHOULD configure "video stream" feature to things work properly.

Here are some useful info on this topic which I tested on wlc version, still concept should be same & it may be useful to you.

1. Wireless multicast not working, why ?

2. Understanding Video Stream feature

3. Configuring Multicast on WLC
