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 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.
Specify a maximum size limit in kilobytes for the total combined
size of all the capture files on the NXC, 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 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.
Set a time limit in seconds for the capture. The NXC 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".
Specify the maximum number of bytes to capture per packet. The
NXC 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.
