:vxdiag_udpstatshow
Use the :vxdiag_udpstatshow command to display User Datagram Protocol
(UDP) statistics for the access point. The UDP statistics might look like this
example:
UDP:
9244 total packets
9227 input packets
17 output packets
0 incomplete header
0 bad data length field
0 bad checksum
9211 broadcasts received with no ports
0 full socket
16 pcb cache lookups failed
0 pcb hash lookup failed
Follow the steps in the “Entering Diagnostic Commands” section on page 9-20 to
open the CLI and enter the :vxdiag_udpstatshow command.
Tracing Packets
Use the packet tracing feature to view packets sent and received by the access
point and by other wireless devices on your network. You can view packets sent
to and received from a single wireless device or several wireless devices, or you
can view all the packets sent and received through the access point’s Ethernet and
radio ports.
The IEEE’s 802.1x authentication standard helps define the content of packets
and is available to IEEE members at http://www.ieee.org.
For information on filtering packets, see the “Filter Setup” section on page 3-8.
Reserving Access Point Memory for a Packet Trace Log File
You can save packet traces in a log file that you view or save, or you can view
packets on the access point command-line interface without storing the traces in
a log file. Use the instructions in this section to reserve access point memory for
