The wireless packet capture feature enables capturing and storing packets received and
transmitted by the WAP device. The captured packets can then be analyzed by a network
protocol analyzer, for troubleshooting or performance optimization. There are two methods of
packet capture:
• Local capture method— Captured packets are stored in a file on the WAP device. The
WAP device can transfer the file to a TFTP server or download by HTTP(S) to a
computer. The file is formatted in pcap format and can be examined using tools such as
Wireshark and OmniPeek.
• Remote capture method—Captured packets are redirected in real time to an external
computer running the Wireshark tool.
The WAP device can capture these 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 on the internal logical interfaces such as VAPs
and WDS interfaces.
