Step 2 Find the wireless device for which you want to trace packets and click the device’s
MAC address. The device’s Station page appears.
Step 3 On the device’s Station page, click the alert checkbox in the To Station header to
trace packets sent to the device. Click the alert checkbox in the From Station
header to trace packets the device sends.
Note Copying packets into access point memory slows the access point’s performance.
When you finish tracing packets, deselect the alert checkboxes on the Station
pages.
If you want the access point to trace packets all the time, reduce the impact on
performance by selecting Record for the External Information setting on the
Event Handling Setup page and select Port Information on the Event Display
Setup page for the “Severity Level at which to display events immediately on the
console” setting. With this configuration, the access point records packets in a log
file but does not spend time instantly displaying packets on the CLI.
Step 4 Click Refresh. Repeat these steps for each device for which you want to trace
packets. The MAC addresses of devices you are tracing appear in red in the
Association Table.
If you are ready to view packet data, skip to the “Viewing Packet Trace Data”
section on page 9-35. If you want to trace all the packets sent through the access
point’s Ethernet and radio ports, follow the instructions in the “Tracing Packets
for Ethernet and Radio Ports” section on page 9-34.
Tracing Packets for Ethernet and Radio Ports
Follow these steps to set up the access point’s Ethernet or radio ports for packet
tracing:
Step 1 To trace all the packets sent and received through the access point’s Ethernet or
radio ports, browse to the Network Ports page. Browse to the Network Ports page
by clicking Current Associations on the Summary Status page or by clicking the
