Packet Capture Parameters
Field Name Field Description
In the Capture Locations pane, configure the following settings:
Appliance Data Ports Select this option to capture packets to and from the appliance. When
capturing appliance data ports, you must configure at least one filter. From
the Add Filters field, select either IP address or MAC address for the
appliance.
Only one capture task can apply to the Appliance Data Ports at a time. If
more than one capture task is started using the Appliance Data Ports, the
last requested task will be started.
Wired Enables wired-packet capture on the selected AP.
Filter packets on the basis of the direction of packet flow:
• In — Capture packets received by the AP.
• Out — Capture packets transmitted by the AP.
• Both — Capture packets transmitted and received by the AP. This is the
default value.
Select Includes Wired Clients to include wired-packets received and
transmitted to and from wired clients associated with the selected AP. This
option is disabled by default.
Wireless Enables wireless-packet capture on the selected AP.
Filter packets on the basis of the direction of packet flow:
• In — Capture packets received by the AP.
• Out — Capture packets transmitted by the AP.
• Both — Capture packets transmitted and received by the AP. This is the
default value.
Specify the radio interface on which to enable wireless-packet capture.
• Radio 1 — Enable packet capture on the AP's radio 1 interface.
• Radio 2 — Enable packet capture on the AP's radio 2 interface.
• Radio 3 — Enable packet capture on the AP4xx radio 3 (Sensor)
interface. Available for AP4xx models only. You must configure an ADSP,
Positioning, or ExtremeLocation profile to capture packets on the sensor
radio.
• All Radios — Enable packet capture on all radio interfaces for the
selected AP. This option is selected by default.
Note: AP39xx and AP3xx, AP4xx, and AP5xx (Centralized site) support
capturing wired and wireless packets simultaneously. The result is one PCAP
file that includes both wired and wireless packets.
In the Settings pane, specify how you want to determine the length of the packet capture. Specify the
duration or manually end packet capture by clicking Stop.
Duration Packet transfer window. Default value is 5 minutes.
Truncate Packet Size
(Bytes)
Number of bytes for the truncated packet. When truncation is configured,
the capture collects up to the configured size of the payload (including the
IP/UDP/TCP headers).
Note: TZSP header is always present. If the truncated packet size is zero, the
TZSP header remains in the packet.
