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.
