Und der Interface-Typ kann mit iw dev wlan0 inof<\/code> ausgegeben werden:
\n
\nInterface wlan0
\n\tifindex 6
\n\twdev 0x2

\n\ttype managed
\n\twiphy 0
\n\tchannel 11 (2462 MHz) HT40-
\n<\/code> <\/p>\n

Manchmal will man aber auch alle Mesh-Points in Funkreichweite sehen, das geht mit
\niw dev wlan0 station dump<\/code>, hier ein Beispiel:
\nStation 77:31:77:e7:77:f9 (on wlan0)
\n\tinactive time:\t730 ms
\n\trx bytes:\t2093412
\n\trx packets:\t14162

\n\ttx retries:\t3
\n\ttx failed:\t0
\n\tsignal: \t-46 [-46] dBm
\n\tsignal avg:\t-45 [-45] dBm
\n\ttx bitrate:\t135.0 MBit\/s MCS 6 40Mhz short GI
\n\trx bitrate:\t121.5 MBit\/s MCS 6 40Mhz
\n\tauthorized:\tyes

\n\tpreamble:\tlong
\n\tWMM\/WME:\tyes
\n\tMFP:\t\tno
\n\tTDLS peer:\tno<\/code><\/p>\n

Alle vorhandenen Pfade mit Ziel-MAC-Adresse und Next-Hope-Adresse wird mit iw dev wlan0 mpath dump<\/code> so angezeigt:
\n
\nDEST ADDR NEXT HOP IFACE\tSN\tMETRIC\tQLEN\tEXPTIME\t\tDTIM\tDRET\tFLAGS
\n<\/code><\/p>\n

Und zu guter letzt, die Abbildung der IP-Adressen auf die MAC-Adressen mit arp<\/code> liefert:
\n
\nIP address HW type Flags HW address Mask Device
