18.3.1 Packet Capture Files

Click Maintenance > Diagnostics > Packet Capture > Files to open the

packet capture files screen. This screen lists the files of packet captures the

NWA3000-N series AP has performed. You can download the files to your

File Size Specify a maximum size limit in kilobytes for the total combined

size of all the capture files on the NWA3000-N series AP, including

any existing capture files and any new capture files you generate.

Note: If you have existing capture files you may need to set

this size larger or delete existing capture files.

The valid range is 1 to 10000. The NWA3000-N series AP stops the

capture and generates the capture file when either the file reaches

this size or the time period specified in the Duration field expires.

Duration Set a time limit in seconds for the capture. The NWA3000-N series

AP stops the capture and generates the capture file when either

this period of time has passed or the file reaches the size specified

in the File Size field. 0 means there is no time limit.

File Suffix Specify text to add to the end of the file name (before the dot and

filename extension) to help you identify the packet capture files.

Modifying the file suffix also avoids making new capture files that

overwrite existing files of the same name.

The file name format is “interface name-file suffix.cap”, for

example “lan-packet-capture.cap”.

Number Of Bytes To

Capture (Per Packet)

Specify the maximum number of bytes to capture per packet. The

NWA3000-N series AP automatically truncates packets that exceed

this size. As a result, when you view the packet capture files in a

packet analyzer, the actual size of the packets may be larger than

the size of captured packets.

Capture Click this button to have the NWA3000-N series AP capture packets

according to the settings configured in this screen.

You can configure the NWA3000-N series AP while a packet capture

is in progress although you cannot modify the packet capture

settings.

The NWA3000-N series AP’s throughput or performance may be

affected while a packet capture is in progress.

After the NWA3000-N series AP finishes the capture it saves a

separate capture file for each selected interface. The total number

of packet capture files that you can save depends on the file sizes

and the available flash storage space. Once the flash storage space

is full, adding more packet captures will fail.

Stop Click this button to stop a currently running packet capture and

generate a separate capture file for each selected interface.

Reset Click this button to return the screen to its last-saved settings.
