Using ping, tracert, and system debugging
Use the ping, tracert, and system debugging utilities to test network connectivity and identify network
problems.
The term "router "in this document refers to both routers and Layer 3 firewalls.
Ping
The ping utility sends ICMP echo requests (ECHO-REQUEST) to the destination device. Upon receiving
the requests, the destination device responds with ICMP echo replies (ECHO-REPLY) to the source device.
The source device outputs statistics about the ping operation, including the number of packets sent,
number of echo replies received, and the round-trip time. You can measure the network performance by
analyzing these statistics.
You can ping the IP address or the host name of the destination device. Output from the ping command
falls into the following types:
• If the target host name cannot be identified, the source device outputs related information.
• If the source device does not receive an ICMP echo reply within the timeout time, it displays the
prompt information and the statistics during the ping operation.
• If the source device receives an ICMP echo reply within the timeout time, it displays the number of
bytes of the echo reply, the message sequence number, Time to Live (TTL), the response time, and
the statistics during the ping operation.
Statistics during the ping operation include number of packets sent, number of echo reply messages
received, percentage of messages not received, and the minimum, average, and maximum response
time.
Executing the ping operation in the Web interface
The Web interface does not support the IPv6 ping operations.
To execute the ping operation in the Web interface:
1. Select Network > Diagnostic Tools from the navigation tree.
The page for executing the ping operation appears.
