Maintenance Tools
Use the maintenance tool commands to check the conditions of other devices through the NWA/
WAC. The maintenance tools can help you to troubleshoot network problems.
Here are maintenance tool commands that you can use in privilege mode.
Table 80 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 NWA/WAC dumps the traffic to /
packet_trace/packet_trace_interface
. Use
FTP to retrieve the files (see Section 18.6 on page 101).
If you do not assign the duration, the NWA/WAC 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 NWA/WAC’s interface(s). Studying
these packet captures may help you identify network
problems.
The no command stops the running packet capture on the
NWA/WAC.
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.
duration <0..300> Sets a time limit in seconds for the capture. The NWA/WAC
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.
