Does the AirPcap and wireshark sniff CCX? or do you need the upgraded AirPcap NX? asked 05 Jul '11, 07:10  aplatek |
One Answer:
I presume CCX are Cisco Compatible eXtensions rather than, say, the Chicago Climate eXchange or this little economy car. It sounds as if, at the network protocol layer, CCX is just some additional protocols and additions to existing Wi-Fi protocols, so any device capable of receiving arbitrary 802.11 packets, such as an AirPcap device, could capture that traffic. Whether Wireshark can recognize those extensions and dissect them, rather than just showing them as unknown protocols/TLVs/etc., is another matter. What the AirPcap Nx provides is support for 802.11n; you won't be able to capture on an 802.11n network with an AirPcap Classic or AirPcap Tx, regardless of whether CCX is being used on the network or not. answered 06 Jul '11, 16:38  Guy Harris ♦♦ |
