If the keyword “Any” is configured for location, it implies that there is no location based filtering for the clients trying to access the device. In case of wired services, the same location does not apply because wired clients do not get associated to the AP.Ģ. Yet, if you want only those devices whose location is same as that of the service instance, the keyword “same” could be configured for such wireless service providers. In case of wireless service instances, the device location can change. As long as the global maximum limit of MAC addresses is not exceeded, any service group can configure as many MAC addresses as desired. This configuration implies that only clients from the same location as that of the device publishing the service can access the service. Since flexibility is desired when configuring the location using the AP-NAME, AP-GROUP, or AP-LOCATION, the administrator has to configure the type of location that is desired. Service limit: 6400 on 2500, 5508, WiSM2 and vWLC and 16000 services on 75 UC Controllers.Įach MAC address is configured with a unique name, which can be the service instance name, and the location of the MAC address for both wired and or wireless.ġ. Routers cannot use multicast routing to redirect the traffic because the time to live (TTL) is set to one, and link-local multicast is meant to stay local by design.Ī service group name can be associated with a set of MAC addresses, and the maximum MAC addresses that can be configured for any service group is limited by the platform dependent global maximum number of service instances that can be discovered, that is, The addresses used by the Bonjour protocol are link-local multicast addresses, and thus are only forwarded to the local L2 domain. Apple’s Bonjour protocol relies on mDNS operating at UDP port 5353 and sent to the following reserved group addresses: – Full screen mirroring in iOS v5.0+ (iPad2, iPhone4S or later)Įach query or advertisement is sent to the Bonjour multicast address for delivery to all clients on the subnet.
