DESCRIPTION
Select this to have the ZyWALL keep capturing traffic and
overwriting old packet capture entries when the available storage
space runs out.
Select this to have the ZyWALL only store packet capture entries
on the ZyWALL.
Select this to have the ZyWALL store packet capture entries only
on a USB storage device connected to the ZyWALL.
Status:
Unused - the connected USB storage device was manually
unmounted by using the Remove Now button or for some reason
the ZyWALL cannot mount it.
none - no USB storage device is connected.
available - you can have the ZyWALL use the USB storage device.
The available storage capacity also displays.
Note: The ZyWALL reserves some USB storage space as a
buffer.
When saving packet captures only to the ZyWALL's onboard
storage, specify a maximum limit in megabytes for the total
combined size of all the capture files on the ZyWALL.
When saving packet captures to a connected USB storage device,
specify a maximum limit in megabytes for each capture file.
Note: If you have existing capture files and have not selected
the Continuously capture and overwrite old ones
option, you may need to set this size larger or delete
existing capture files.
The valid range is 1 to 10000. The ZyWALL 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.
Specify a maximum size limit in megabytes for individual packet
capture files. After a packet capture file reaches this size, the
ZyWALL starts another packet capture file.
Set a time limit in seconds for the capture. The ZyWALL 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.
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 "vlan2-packet-capture.cap".
