ZyWALL (ZLD) CLI Reference Guide

346

duration <0..300> Sets 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 using

the files-size command below. 0 means there

is no time limit.

file-suffix <profile_name> Specifies 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”.

files-size <1..10000> Specify a maximum size limit in kilobytes for the

total combined size of all the capture files on the

ZyWALL, including any existing capture files and

any new capture files you generate.

The ZyWALL stops the capture and generates the

capture file when either the file reaches this size or

the time period specified ( using the duration

command above) expires.

Note: If you have existing capture files

you may need to set this size larger

or delete existing capture files.

host-ip {ip-address | profile_name | any> Sets a host IP address or a host IP address object

for which to capture packets. any means to capture

packets for all hosts.

host-port <0..65535> If you set the IP Type to any, tcp, or udp using the

ip-type command below, you can specify the

port number of traffic to capture.

iface {add | del} {interface_name |

virtual_interface_name}

Adds or deletes an interface or a virtual interface

for which to capture packets to the capture

interfaces list.

ip-type {icmp | igmp | igrp | pim | ah |

esp | vrrp | udp | tcp | any}

Sets the protocol of traffic for which to capture

packets. any means to capture packets for all

types of traffic.

snaplen <68..1512> Specifies the maximum number of bytes to capture

per packet. The ZyWALL 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.

show packet-capture status Displays whether a packet capture is ongoing.

show packet-capture config Displays current packet capture settings.
