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 180 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
to
/packet_trace/
packet_trace_interface
. Use FTP to
retrieve the files (see Section 35.6 on page 278).
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.
