Network trace configuration
Overview
Network administrators can perform network traces to capture and analyze network traffic.
Network trace operates in two modes:
• Packet file trace mode: Captured packets are stored in a file on the M220. The M220
can transfer the file to a TFTP server. The file is formatted in pcap format and can be
examined using tools such as Wireshark and OmniPeek.
• Remote packet trace mode: The captured packets are redirected in real time to an
external PC running the Wireshark tool.
The AP can trace the following types of packets:
• 802.11 packets received and transmitted on radio interfaces. Packets captured on radio
interfaces include the 802.11 header.
• 802.3 packets received and transmitted on the Ethernet interface.
• 802.3 packets received and transmitted within wireless communities or on internal logical
interfaces, such as WDS interfaces.
To configure network trace settings and initiate packet captures, select Tools > Network
trace.
