Using Diagnostic Tools

Using Diagnostic Tools

NOTE
Cisco RV220W Administration Guide
The RV220W provides several diagnostic tools. To access these tools, choose
Administration > Diagnostics > Network Tools.

Using PING

This utility can be used to test connectivity between this router and another
device on the network connected to this router. Enter an IP address and click Ping.
A popup window appears, indicating the ICMP echo request status. To ping
through the VPN tunnel, check the box.

Using Traceroute

This utility will display all the routers present between the destination IP address
and the RV220W. Up to 30 "hops" (intermediate routers) between this router and
the destination will be displayed. Enter an IP address and click Traceroute.

Performing a DNS Lookup

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. A message stating "Unknown
Host" indicates that the specified Internet Name does not exist.

Capturing and Tracing Packets

Capture Packets allows you to capture all packets that pass through the selected
interface (LAN, dedicated WAN, or optional WAN). To capture packets, click Packet
Trace, and a new window appears. Select the interface and click Start. To stop the
packet capture, click Stop. You can click Download to save a copy of the packet
capture.
The packet trace is limited to 1MB of data per capture session. When the capture
file size exceeds 1MB, it will be deleted automatically and a new capture file will be
created.
