I've been doing a lot of researching regarding medianet. I would like to entertain introducing a small footprint in the environment, but need a few questions answered.
1. Do Cisco phones have MSI installed in order to be media net announcers/flow producers? If so, what models and firmware versions if applicable?
2. Can media net be enabled and used for QoS on an access switch for an initial implementation with no upstream speakers? So, use medianet on the access switch and just pass along the QoS markings to the upstream distribution switch to fall in line with existing enterprise QoS policy.
3. Taking an access port for example. With medianet enabled on the access port, can you apply an ingress policy that has a medianet class or am I totally missing the point? Example config below.
! class-map match-any MEDIA-CONTROL match application cisco-phone signaling-type sip match application cisco-phone signaling-type h323 match application cisco-phone signaling-type skinny match application cisco-phone signaling-type mgcp ! class-map match-any MEDIA-PAYLOAD match application cisco-phone transport-type rtp !
policy-map INBOUND-MARKING class MEDIA-PAYLOAD set dscp ef class MEDIA-CONTROL set dscp af31 class class-default set dscp 0

I just tested this in my environment and if the WOL server sends out a directed broadcast there is no need for the helper addresses on the Wake On LAN server environment. The only thing you need to do is enable ip directed-broadcast oon the client subnets. Microsoft SCCM is capable of this, and you can find a free utility to test such as WOLcmd.exe that also performs directed broadcasts.
