This command is only valid for the datasource key “X240”, “X500”, “X500e” or “X700”. This command is an optional command to allow for configuration of the Wi-Fi channel width, which may result in a 20, 40, 80, 160, 320, 320-1, or 320-2 MHz wide channel when capturing traffic in an 802.11 environment. Note the values 320, 320-1, and 320-2 are only valid for X500e and X700 Wi-Fi-7 6GHz channels. A few of the control channel frequencies only have one choice for a 320 MHz wide channel and can use the 320 value. For the control channel frequencies that have two choices for 320 MHz wide channels you can use 320-1 or 320-2 as appropriate. Also note you can use the value 320 with a control channel that has two choices for 320 MHz and it will automatically default to pick the 320 MHz-1 wide channel.
“channelwidth= <value>”
Example – “channelwidth=-40”
