Packet Capture
Cisco Small Business WAP551 and WAP561 Wireless-N Access Point 46
3
• Radio Client Filter—Enables or disables the WLAN client filter to capture
only frames that are transmitted to, or received from, a WLAN client with a
specified MAC address.
• Client Filter MAC Address—Specifies the MAC address for WLAN client
filtering.
NOTE The MAC filter is active only when a capture is performed on an
802.11 interface.
• Packet Capture Method—Select one of these options:
- Local File—Captured packets are stored in a file on the WAP device.
- Remote—Captured packets are redirected in real time to an external
computer running the Wireshark tool.
STEP 2 Depending on the selected method, refer to the steps in the Local Packet Capture
or Remote Packet Capture section to continue.
NOTE Changes to packet capture configuration parameters take affect after packet
capture is restarted. Modifying the parameters while the packet capture is running
does not affect the current packet capture session. To begin using new parameter
values, an existing packet capture session must be stopped and restarted.
To initiate a local packet capture:
STEP 1 Ensure that Local File is selected for the Packet Capture Method.
STEP 2 Configure these parameters:
• Capture Interface—Enter a capture interface type for packet capture:
- radio1—802.11 traffic on Radio 1.
- radio2—802.11 traffic on Radio 2 (WAP561 only).
- eth0—802.3 traffic on the Ethernet port.
- VAP0 or WLAN0:VAP0—VAP0 traffic. For WAP561, this shows as
WLAN0:VAP0, where WLAN0 represents Radio 1.
- WLAN1:VAP0—VAP0 traffic on Radio 2 (for WAP561 devices only).
- VAP1 to VAP15, if configured—Traffic on the specified VAP. For WAP561,
the interface names are preceded by WLAN0: or WLAN1:, where WLAN0
represents Radio 1 and WLAN1 represents Radio 2.
