Queries routers and switches.

Ranks devices according to the likelihood they are rogues.

Multiple tests to eliminate false positive results.

Provides rogue discovery that identifies the switch and port to which a rogue device is connected.

Master Console and Failover

The AWMS Master Console and Failover tools enable network-wide information in easy-to-understand
presentation, to entail operational information and high-availability for failover scenarios. The benefits of these
tools include the following:
Provides network-wide visibility, even when the WLAN grows to 50,000+ devices.

Executive Portal allows executives to view high-level usage and performance data.

Aggregated Alerts

Failover

Many-to-one failover

One-to-one failover

The Master Console and Failover servers can be configured with a Device Down trigger that generates an alert if
communication is lost. In addition to generating an alert, the Master Console or Failover server can also send
email or NMS notifications about the event. See

Integrating AWMS into the Network and Organizational Hierarchy

AWMS generally resides in the NOC and communicates with various components of your WLAN infrastructure.
In basic deployments, AWMS communicates solely with indoor wireless access points and WLAN controllers
over the wired network. In more complex deployments AWMS seamlessly integrates and communicates with
authentication servers, accounting servers, TACACS+ servers, routers, switches, network management servers,
wireless IDS solutions, help systems, indoor wireless access points, mesh devices, and WiMAX devices.
AWMS has the flexibility to manage devices on local networks, remote networks, and networks using Network
Address Translation (NAT). AWMS communicates over-the-air or over-the-wire utilizing a variety of protocols.
The power, performance, and usability of the AWMS solution become more apparent when considering the
diverse components within a Wireless LAN.
