Maintenance Tools

Use the maintenance tool commands to check the conditions of other devices through the

ZyWALL. The maintenance tools can help you to troubleshoot network problems.

Here are maintenance tool commands that you can use in privilege mode.

Table 194 Maintenance Tools Commands in Privilege Mode

COMMAND DESCRIPTION

packet-trace [interface interface_name] [ip-

proto {<0..255> | protocol_name | any}] [src-

host {ip | hostname | any}] [dst-host {ip |

hostname | any}] [port {<1..65535> | any}]

[file] [duration <1..3600>] [extension-filter

filter_extension]

traceroute {ip | hostname}

Sends traffic through the specified interface with

the specified protocol, source address, destination

address, and/or port number.

If you specify

file, the ZyWALL dumps the traffic

/packet_trace/

packet_trace_interface

. Use FTP to

retrieve the files (see Section 37.6 on page 316).

If you do not assign the duration, the ZyWALL

keeps dumping traffic until you use Ctrl-C.

Use the extension filter to extend the use of this

command.

protocol_name: You can use the name, instead

of the number, for some IP protocols, such as

tcp,

udp, icmp, and so on. The names consist of 1-16

alphanumeric characters, underscores (_), or

dashes (-). The first character cannot be a number.

hostname: You can use up to 252 alphanumeric

characters, dashes (-), or periods (.). The first

character cannot be a period.

filter_extension: You can use 1-256

alphanumeric characters, spaces, or '()+,/

:=?;!*#@$_%.- characters.

traceroute {ip | hostname} Displays the route taken by packets to the specified

destination. Use

Ctrl+c when you want to return

to the prompt.

[no] packet-capture activate Performs a packet capture that captures network

traffic going through the set interface(s). Studying

these packet captures may help you identify

network problems.

The no command stops the running packet capture

on the ZyWALL.

Note: Use the packet-capture

configure command to configure

the packet-capture settings before

using this command.

packet-capture configure Enters the sub-command mode.
