This can be caused by the UPNP Multicast group used by Chromecast not being permitted by default. 

 Resolution         

Enable multicast group 239.255.255.250 on the wireless controller from the Web GUI with the following process:

Click Controller > Network > Topologies

Click the Topology Chromecast is connected to

Click Multicast filters tab

Click Multicast Bridging check box

Click IP group Radio button and add 239.255.255.250/32

Click Save

Will this have any affect on any other wireless devices or will this only matter to the chromecast. I'm in the same situation and just want to make sure this won't mess up our laptops.

The info is in the KB as well, pretty much what Rob said:

Chromecast is not connecting or streaming on IdentiFi wireless

I understand this will fix the chromecast issue. I just want to verify that enabling Multicast Bridging will not cause conflicts with other wireless devices on the network like laptops or phones.

If you are allowing a specific group like the article suggests vs ALL multicast then it should not cause issues, unless the rates for that group are high.

It's recommended to put that kind of devices in a dedicated VLAN/topology.
Here a link to the "The Extreme Networks Solution for Apple Bonjour Traffic Management"....
http://pages.enterasys.com/AppleBonjourTrafficManagement_lp.html

Because the setting is only enabled on this VLAN/topology the other VLAN/topology are not "affected".
