DESCRIPTION
Enabled interfaces (except for virtual interfaces) appear under Available
Interfaces. Select interfaces for which to capture packets and click the right arrow
button to move them to the Capture Interfaces list. Use the [Shift] and/or [Ctrl]
key to select multiple objects.
Select the version of IP for which to capture packets. Select any to capture packets
for all IP versions.
Select the protocol of traffic for which to capture packets. Select any to capture
packets for all types of traffic.
Select a host IP address object for which to capture packets. Select any to capture
packets for all hosts. Select User Defined to be able to enter an IP address.
This field is configurable when you set the IP Type to any, tcp, or udp. Specify the
port number of traffic to capture.
Select this to have the ZyWALL/USG keep capturing traffic and overwriting old
packet capture entries when the available storage space runs out.
Select this to have the ZyWALL/USG only store packet capture entries on the
ZyWALL/USG. The available storage size is displayed as well.
Note: The ZyWALL/USG reserves some onboard storage space as a buffer.
Select this to have the ZyWALL/USG store packet capture entries only on a USB
storage device connected to the ZyWALL/USG if the ZyWALL/USG allows this.
Status:
Unused - the connected USB storage device was manually unmounted by using the
Remove Now button or for some reason the ZyWALL/USG cannot mount it.
none - no USB storage device is connected.
service deactivated - USB storage feature is disabled (in Configuration >
Object > USB Storage), so the ZyWALL/USG cannot use a connected USB device
to store system logs and other diagnostic information.
available - you can have the ZyWALL/USG use the USB storage device. The
available storage capacity also displays.
Note: The ZyWALL/USG reserves some USB storage space as a buffer.
When saving packet captures only to the ZyWALL/USG's onboard storage, specify a
maximum limit in megabytes for the total combined size of all the capture files on
the ZyWALL/USG.
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 depends on the available onboard/USB storage size. The ZyWALL/
USG 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/USG starts another packet
capture file.
