I recently enabled multicast on the wireless to a VLAN that only has one SSID(Private) but for some reason when i go to monitor>multicast on the controller i see that there are other clients on the from another multicast group from another VLAN (Guest) which i didnt enable multicast on and it doesnt have the same SSID as the other one.
I was wondering if this suppose to work this way.
Thank you
Vic

That is the IGMP list that you are seeing, so any IGMP request the WLC heard is going to be listed.

you coud ACL off the interfaces that you dont' want multicast on, and deny any 239.x.x.x in/out

Stephen,
Is there way to filter that ?, because all that multicast traffic is getting to the CORE like the SSDP traffic using the 239.255.255.250 address.
Thank you

Thanks, will do that.
Do you suggest to apply the ACL on the controllers or from the CORE ?

Victior. personally Im not a fan of ACLs on the WLC. I would put it on the wired side... If you havent done a ACL on a controller before... Its a big PITA..
