Configuring AirGroup Services

AirGroup is a zero configuration networking protocol that enables service discovery, address assignment, and name resolution for desktop computers, mobile devices, and network services. It is designed for flat, single-subnetSubnet is the logical division of an IP network. IP networks such as wireless networking at home.

Bonjour can be installed on computers running Microsoft Windows and is supported by the new network-capable printers. Bonjour uses multicast DNSDomain Name System. A DNS server functions as a phone book for the intranet and Internet users. It converts human-readable computer host names into IP addresses and IP addresses into host names. It stores several records for a domain name such as an address 'A' record, name server (NS), and mail exchanger (MX) records. The Address 'A' record is the most important record that is stored in a DNS server, because it provides the required IP address for a network peripheral or element. (mDNSMulticast Domain Name System. mDNS provides the ability to perform DNS-like operations on the local link in the absence of any conventional unicast DNS server. The mDNS protocol uses IP multicast User Datagram Protocol (UDP) packets, and is implemented by the Apple Bonjour and Linux NSS-mDNS services. mDNS works in conjunction with DNS Service Discovery (DNS-SD), a companion zero-configuration technique specified. See RFC 6763.) to locate devices and the services offered by these devices. The AirGroup solution supports both wired and wireless devices. Wired devices that support Bonjour services are part of AirGroup when connected to a VLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. that is terminated on the Virtual Controller.

In addition to the mDNS protocol, Instant Access Points (IAPs) also support UPnPUniversal Plug and Play. UPnp is a set of networking protocols that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi APs, and mobile devices to seamlessly discover each other's presence on the network and establish functional network services for data sharing, communications, and entertainment., and DLNADigital Living Network Alliance. DLNA is a set of interoperability guidelines for sharing digital media among multimedia devices. enabled devices. DLNA is a network standard derived from UPnP, which enables devices to discover the services available in a network.

DLNA also provides the ability to share data between the Windows or Android-based multimedia devices. All the features and policies applicable to mDNS are extended to DLNA to ensure full interoperability between compliant devices.

AirGroup Features

AirGroup provides the following features:

• Send unicast responses to mDNS queries and reduces mDNS traffic footprint.
• Ensure cross-VLAN visibility and availability of AirGroup devices and services.
• Allow or block AirGroup services for all users.
• Allow or block AirGroup services based on user roles.
• Allow or block AirGroup services based on VLANs.

AirGroup Services

Bonjour supports zero-configuration services. The services are pre-configured and are available as part of the factory default configuration. The administrator can also enable or disable any or all services.

The following services are available for IAP clients:

• AirPlay — Apple AirPlay allows wireless streaming of music, video, and slide shows from your iOS device to Apple TV and other devices that support the AirPlay feature.
• AirPrint — Apple AirPrint allows you to print from an iPad, iPhone, or iPod Touch directly to any AirPrint compatible printer.
• iTunes— The iTunes service is used by iTunes Wi-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. sync and iTunes home-sharing applications across all Apple devices.
• RemoteMgmt— Use this service for remote login, remote management, and FTPFile Transfer Protocol. A standard network protocol used for transferring files between a client and server on a computer network. utilities on Apple devices.
• Sharing— Applications such as disk sharing and file sharing, use the service ID that are part of this service on one or more Apple devices.
• Chat— The iChat® (Instant Messenger) application on Apple devices uses this service.
• ChromeCast—The ChromeCast service allows you to use a ChromeCast device to play audio or video content on a high-definition television by streaming content through Wi-Fi from the Internet or local network.
• DLNA Media—Applications such as Windows Media Player use this service to browse and play content on a remote device.
• DLNA Print—This service is used by printers that support DLNA.

To enable AirGroup services:

1. In the Network Operations app, set the filter to a group that contains at least one AP. The dashboard context for the group is displayed.
2. Under Manage, click Devices > Access Points.
3. Click the Config icon. The tabs to configure access points is displayed.
4. Click Show Advanced, and click Services tab. The Services page is displayed.
5. Click the AirGroup accordion.
6. Select the AirGroup check-box.

   The mDNS (Bonjour) and SSDP (DLNA/UPNP) check-boxes are selected by default.

   Select at least mDNS (Bonjour) or SSDP (DLNA/UPNP) to proceed further.

   Optionally, select the Guest Bonjour Multicast check-box to allow guest users to use the Bonjour services that are enabled in a guest VLAN. When Guest Bonjour Multicast is enabled, the Bonjour devices are visible only in the guest VLAN and AirGroup does not discover or enforce policies in guest VLAN.

7. Under the AirGroup Settings sub-accordion, select the check-box against one or more AirGroup services listed in AirGroup Services.

   • Optionally, when enabling an AirGroup service, define disallowed roles. The disallowed roles are not allowed to use the specific AirGroup service. To disallow roles:

     1. Click Edit against Disallowed Roles.
     2. Move the roles from the Available pool to the Selected pool.
     3. Click Ok.

   • Optionally, when enabling an AirGroup service, define disallowed VLANs. The disallowed VLANs are not allowed to use the specific AirGroup service. To disallow VLANs:

     1. Click Edit against Disallowed VLANs.
     2. Type the VLANs in Enter comma-separated list of VLAN IDs. Separate multiple VLANs with a comma.
     3. Click Ok.

   • Optionally, configure and enable a new AirGroup service. If defined, disallowed roles or VLANs are not allowed to use the new AirGroup service. To configure and enable a new AirGroup service:

     1. Click Add New Service.
     2. Type the service name in Service Name. Use alphanumeric characters.
     3. Type a service ID in Service ID. Use + to add additional service IDs.

   • Sample service ID: urn:schemas-upnp-org:service:RenderingControl:1 or _sleep-proxy._udp.

     1. Click Ok.
