LABEL

DESCRIPTION

Interfaces

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.

IP Version

Select the version of IP for which to capture packets. Select any to capture packets
for all IP versions.

Protocol Type

Select the protocol of traffic for which to capture packets. Select any to capture
packets for all types of traffic.

Host IP

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.

Host Port

This field is configurable when you set the IP Type to any, tcp, or udp. Specify the
port number of traffic to capture.

Continuously capture
and overwrite old ones

Select this to have the ZyWALL keep capturing traffic and overwriting old packet
capture entries when the available storage space runs out.

Save data to onboard
storage only

Select this to have the ZyWALL only store packet capture entries on the ZyWALL.
The available storage size is displayed as well.

Note: The ZyWALLL reserves some onboard storage space as a buffer.

Save data to USB
storage

Select this to have the ZyWALL store packet capture entries only on a USB storage
device connected to the ZyWALL if the ZyWALL allows this.

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.

service deactivated - USB storage feature is disabled (in Configuration >
Object > USB Storage), so the ZyWALL cannot use a connected USB device to
store system logs and other diagnostic information.

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.

Captured Packet Files

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 depends on the available onboard/USB storage size. 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.

Split threshold

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.
