Chapter 10: Packet Capture
Wi-Fi Packet Capture

either a single 20 MHz channel or, for higher performance, use
two, consecutive 20 MHz channels i.e., a 40 MHz bonded channel.
Access points supporting 802.11ac allow capture from 20, 40, or
80 MHz channels (OneTouch AT G2 only). Adjacent 20 MHz
subchannels are grouped into pairs to make 40 MHz channels,
and adjacent 40 MHz subchannels are grouped into pairs to make
80 MHz channels.
When capturing traffic for an access point that is configured to
use a 40 MHz bonded channel, the channel mode should be set to
40 MHz + (primary channel plus adjacent higher channel number)
or 40MHz – (primary channel plus adjacent lower channel
number), to match the access point configuration. Only
permissible bonding options are available based on the selected
channel; e.g., channel 34 bonding can only be 40 MHz + because
it is the first channel in the 5 GHZ band. If a bonded channel is not
configured correctly, some packets will be missing from the
capture.
Device BSSID/MAC
Enter a BSSID to capture only packets going to or from the target
device.
