|
Definition
| A virtual MAC address allocated to an interferer by a detecting SAgE chipset, so as to be able to allocate a unique identifier to each detected interferer. |

Term
|
Definition
| An access point that is not managed by your WLCs. One of these can be an access point from your organization, managed by another system (friendly, internal one), a valid neighboring AP (friendly, external one), or an attacker AP posing a threat to your network (malicious one). |

| Spectrum Analysis Engine (SAgE) |
|
Definition
| a specialized chip on most Cisco APs that can read, demodulate, and interpret non-802.11 signals to report interferers. |

Term
| Spectrum Intelligence (SI) |
|
Definition
| a software-based non-802.11 interferer-detection mechanism implemented on lower-end Cisco APs that do not include a SAgE chipset. |

Term
|
Definition
| The state on the WLC of a client of a WebAuth WLAN that successfully associated and authenticated, obtained an IP, and moved to the WebAuth authentication phase. As this phase is manual while the previous phases of the association are usually automatic, some clients may stay in this state for a long time (until the user notices the authentication requirement on the device screen). |
