Cisco Small Business WAP551 and WAP561 Wireless-N Access Point
When a Bonjour-enabled WAP device is attached to a network, any Bonjour client can
discover and get access to the configuration utility without prior configuration.
A system administrator can use an installed Internet Explorer plug-in to discover the WAP
device. The web-based configuration utility shows up as a tab in the browser.
Bonjour works in both IPv4 and IPv6 networks.
Bonjour is enabled by default. To change the administrative status:
Select Administration > Discovery - Bonjour in the navigation pane.
Discovery—Bonjour
Click Enable to enable Bonjour or uncheck Enable to disable Bonjour.
Click Save. The changes are saved to the Startup Configuration.
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. 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.
