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. Packet capture can operate in one of two methods:
• 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. 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. 1 1 packets received and transmitted on radio interfaces. Packets
captured on radio interfaces include the 802. 1 1 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.
