pcap

pcap {start <bssid> <ip> <port> <format> <maxlen> [<channel>]|stop <bssid> <id>}

Description

This command configures the wireless packet capture on an Instant AP and send the packets to a client packet analyzer utility like Airmagnet, Wireshark and so on, on a remote client.

Before using this command, you need to start the packet analyzer utility on the client and open a capture window for the port from which you are capturing packets. The packet analyzer cannot be used to control the flow or type of packets sent from the Instant APs.

The packet analyzer processes all packets. However, you can apply display filters on the capture window to control the number and type of packets being displayed. In the capture window, the timestamp displayed corresponds to the time that the packet is received by the client and is not synchronized with the time on the Instant AP.
