The story is that we recently upgraded our 4404 controller to the new 18.104.22.168 code. This upgrade was from 4.2.209 code. I would like to make the change to the Multicast setup so that It is multcasted and not unicasted.
So I went into the controller and selected MULTICAST for AP multicast mode and entered in a multicast ip of 22.214.171.124 ( default choosen in the cisco howto's)
I enabled Multicast globally
I then test the reason for enabling the multicast and it doesnt work. The problem is that the Wireless HP printers setup to use Apples IPRINT are not able to be found. However, when I select the Multicast setting for the APs to be UNICAST the Ipads can find the Printers and print to them.....
What am I doing wrong with this Multicast setting? Do i need to add a Multicast address to the router?
