Ping

You can ping other devices on the network directly from
the device. The Ping tool uses Internet Control Message
Protocol (ICMP) packets to check the preliminary link
quality and packet latency estimation between two
network devices.

Select Destination IP

You have two options:

• Select a remote system IP from the drop-down list,

which is generated automatically.

• Select specify manually and enter the IP address in the

field displayed below.

Click the icon to refresh the list of remote system IP
addresses.

Packet Count

Enter the number of packets to send for

the ping test.

Packet Size

Enter the size of the packet.

Start

Click Start to start the test.

After the test is completed, the Ping tool reports the
following information for each packet sent:

Host

Displays the IP address of the remote host.

Time

Displays the round-trip time in ms.

TTL

Displays the Time To Live (TTL), the number of hops

allowed before the ping test fails.

Results

The Ping tool reports packet loss statistics and

round-trip time evaluation:

Packet Loss

Displays the percentage of packets lost

and number of packets received.

Min

Displays the minimum round-trip time in ms.

Avg

Displays the average round-trip time in ms.

Max

Displays the maximum round-trip time in ms.

Traceroute

The Traceroute tool traces the hops from the device to a
specified destination host name or IP address. Use this
tool to find the route taken by ICMP packets across the
network to the destination host.

Destination Host

Enter the host name or IP address of

the destination host.

Resolve IP Addresses

Select this option to resolve

and print hop IP addresses symbolically rather than
numerically.

Start

Click Start to start the test.

After the test is completed, the Traceroute tool reports the
following information for each hop:

#

Displays the hop number.

Host

Displays the hostname, identifier, or IP address of

the hop host.

IP

Displays the IP address of the hop host.

Response

Displays the round-trip times from the device

to the hop host. There are three packets sent per hop, so
there should be three round-trip times displayed. If there
is no response from the hop host within the timeout
interval of 5 seconds, “*” is displayed.
