Using Diagnostic Tools
Your device provides several diagnostic tools to help you troubleshoot network
problems.
•
Network Tools
•
Configuring Port Mirroring
Network Tools
Use network tools to troubleshoot the network.
Using PING
You can use the PING utility to test connectivity between this router and another
device in the network. You can also use the Ping tool to test connectivity to the
Internet by pinging a fully qualified domain name (for example, www.cisco.com).
To use PING:
STEP 1
Choose
Administration
>
Diagnostics
>
Network Tools
.
STEP
2
In the
IP Address / Domain Name
field, enter the device IP address or a fully
qualified domain name such as www.cisco.com to ping.
STEP
3
Click
Ping
. The ping results appear. These results tell you if the device is
reachable.
Using Traceroute
The Traceroute utility displays all the routers present between the destination
IP address and this router. The router displays up to 30 hops (intermediate routers)
between this router and the destination.
To use Traceroute:
STEP 1
Choose
Administration
>
Diagnostics
>
Network Tools
.
STEP
2
In the
IP Address / Domain Name
field, enter the IP address to trace.
STEP
3
Click
Traceroute
. The Traceroute results appear.

Performing a DNS Lookup
You can use the Lookup tool to find out the IP address of host (for example, a Web,
FTP, or Mail server) on the Internet.
To retrieve the IP address of a Web, FTP, Mail or any other server on the Internet,
type the Internet name in the text box and click
Lookup
. If the host or domain entry
exists, you will see a response with the IP address. An Unknown Host message
indicates that the specified Internet name does not exist.
To use the Lookup tool:
STEP 1
Choose
Administration
>
Diagnostics
>
Network Tools
.
STEP
2
In the
Internet Name
field, enter the Internet name of the host.
STEP
3
Click
Lookup
. The nslookup results appear.
Configuring Port Mirroring
Port mirroring monitors network traffic by sending copies of all incoming and
outgoing packets from one port to a monitoring port. You can use port mirroring as
a diagnostic or debugging tool, especially when fending off an attack or viewing
user traffic from LAN to WAN to see if users are accessing information or websites
they are not supposed to.
The LAN host (PC) should use a static IP address to avoid any issues with port
mirroring. DHCP leases can expire for a LAN host and can cause port mirroring to
fail if a static IP address is not configured for the LAN host.
To configure port mirroring:
STEP 1
Choose
Administration
>
Diagnostics
>
Port Mirroring
.
STEP
2
In the
Mirror Source
field, select the ports to mirror.
STEP
3
From the
Mirror Port
drop-down menu, choose a mirror port. If you use a port for
mirroring, do not use it for any other traffic.
STEP
