AirGroup

AirGroup The application that allows the end users to register their personal mobile devices on a local network and define a group of friends or associates who are allowed to share them. AirGroup is primarily designed for colleges and other institutions. AirGroup uses zero configuration networking to allow Apple mobile devices, such as the AirPrint wireless printer service and the AirPlay mirroring service, to communicate over a complex access network topology. is a unique enterprise-class capability that leverages zero configuration networking to allow mobile device technologies, like the AirPrint wireless printer service or the AirPlay mirroring service, to communicate over a complex access network topology.

AirGroup Enhancements

AirGroup is redesigned to meet the scaling and serviceability requirements of networks with large number of devices.

 

AirGroup can operate in version 1 (older architecture) or version 2 (redesigned architecture) mode. AirGroup version 2 mode is available as a Beta release. Contact Aruba Support to enable AirGroup version 2 mode. By default, AirGroup operates in version 1 mode. AirGroup version 2 mode is applicable only on Mobility Conductor.

The AirGroup enhancements include:

Making AirGroup multi-threaded and lock-less. This reduces packet corruption and process crashes.

Handling increased frequency of server advertisements. This increases scaling in networks with large number of devices.

Handling increased frequency of client queries. This increases scaling in networks with large number of devices.

Flushing wireless devices that are unresponsive or disconnected from the network. This improves the performance of AirGroup process.

Allowing users to see only servers that are near them. This improves user experience in multiple island scenario.

Enabling auto-associate AP name by default. This improves user experience in multiple island scenario.

Processing larger number of packets per second. This increases scaling in networks with large number of devices.

Improving serviceability with commands. The following AirGroup commands are updated:

airgroup version <ver1>|<ver2> switches between version 1 (older architecture) or version 2 (redesigned architecture) mode. By default, AirGroup operates in version 1 mode. This command is applicable only on Mobility Conductor.

Wired Location Tagging

In the redesigned architecture, every wired server has a location context. New location flags are introduced to tag wired servers. Use the show airgroup servers command to see the flags. The following flags are available for wired servers:

M—Managed Device location

U—Unknown location

R—Cluster location

C—CPPM policy

A—AP location

Wired servers with shared VLAN Virtual 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. across non-clustered managed devices have the U flag. Servers with U flag cannot be discovered by users. The show airgroup multi-controller table command displays the managed devices with shared VLAN Virtual 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..

CPPM State

Wired servers with U flag can be tagged to a location using a CPPM policy. Wired servers with a CPPM policy have the C flag. The CPPM states are:

NR—Not required

Req 1/2/3—Request Attempt number

Fail—CPPM Request failed

Done—CPPM request done

No policy—No Policy in Clearpass Global CPPM State - Req 1

Scalability

The redesigned AirGroup offers the following scalability performance:

Limitations

In both, AirGroup version 1 (older architecture) and version 2 (redesigned architecture), AirGroup does not support the following features:

  • Domain configuration is not supported for AirGroup running in distributed mode.
  • Distributed mode can be used only if there is no requirement for domain configuration.
