To check and reclassify rogue devices, follow these steps: 1. Navigate to the Rogue > Detail page for the device, as shown in Figure Figure 21 Rogue Detail Page Illustration 32 | Dell-Specific Capabilities in AWMS Dell PowerConnect W AirWave 7.2 | Best Practices Guide... - Page 35 All rogue devices will be set to a default controller classification of unclassified when WMS is first offloaded except for devices classified as valid. Rogue devices classified in Dell PowerConnect ArubaOS as valid will also be classified within AWMS as valid for their controller classification as well. As APs report subsequent classification information about rogues, this classification will be reflected within AWMS UI and propagated to controllers that AWMS manages.
