Field Description
Field Description
BSSID MAC address of the SSID used by the detected device.
Vendor Company that manufactures or sells the rogue device.
Class Classification of the rogue device:
❑ rogue—Wireless device that is not supposed to be on the network. The client's MAC
address as well as the client's Destination MAC address are compared to an MX FDB. If
either one of the addresses is in the FDB on ANY MX in the mobility-domain, then the
AP that the client is associated with isclassified as a Rogue device.
❑ intfr—Wireless device that is not part of your network but is not a rogue. The device does
not have an entry in an MX FDB and is not actually on the network, but might be
causing RF interference with MP radios.
❑ known—Device that is a legitimate member of the network.
AP Name Name of the AP that detected the rogue.
Channel The channel that is performing the RF detection.
RSSI Received signal strength indication (RSSI)—the strength of the RF signal detected by the
MP radio, in decibels referred to 1 milliwatt (dBm).
Age Number of seconds since an MP radio last detected 802.11 packets from the device.
SSID The SSID of the device
+/- If the device is using 40 MHz wide channels, the primary channel is listed in the Ch column.
If the secondary channel is above the primary, a “-” appears next to the channel number. If
the secondary channel is below the primary, a “+” appears next to the channel number.
