Misc setting
Save data to onboard
storage only
Select this to have the NXC only store packet capture entries on the NXC. The available
storage size is displayed as well.
Note: The NXC reserves some onboard storage space as a buffer.
Save data to USB
storage
Select this to have the NXC store packet capture entries only on a USB storage device
connected to the NXC.
Status:
Unused - the connected USB storage device was manually unmounted by using the
Remove Now button or for some reason the NXC cannot mount it.
none - no USB storage device is connected.
available - you can have the NXC use the USB storage device. The available storage
capacity also displays.
service deactivated - the USB storage feature is disabled and the NXC cannot use a
connected USB device to store the system log and other diagnostic information.
Note: The NXC reserves some USB storage space as a buffer.
Captured Packet Files When saving packet captures only to the NXC’s onboard storage, specify a maximum
limit in megabytes for the total combined size of all the capture files on the NXC.
When saving packet captures to a connected USB storage device, specify a maximum
limit in megabytes for each capture file.
The valid range depends on the AP’s available storage size. The NXC 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 NXC has the AP stop the capture and
generate the capture file when either this period of time has passed or the file reaches
the size specified in the Captured Packet Files field. 0 means there is no time limit.
