WDS – Multicasting

Hello,

I’ve been able to deploy images using unattend files.
I’d like to start using multicasting as i need to deploy to 160 machines. I am able to create multicast sessions from the server, but am unable to get the client to boot into these sessions.
I know it depends if the switch can handle multitasking – how do i find this out?
If the switch is capable of multitasking, what else should i be looking for??
Thanks,
