Use the "ping" command to troubleshoot network connections
Use the ping command troubleshoot connectivity problems. See the ping command description for
command syntax and examples.
Stop ping commands
To stop pings when the number of pings to send (the count parameter) has been set to a high value,
enter Ctrl+C.
Ping to check internet connection
To check your internet connection, enter:
ping 8.8.8.8
Use the "traceroute" command to diagnose IProuting problems
Use the traceroute command to diagnose IProuting problems. This command traces the route to a
remote IP host and displays results. The traceroute command differs from ping in that traceroute
shows where the route fails, while ping simply returns a single error on failure.
See the traceroute command description for command syntax and examples. The traceroute
command has several parameters, but they are generally not used or required:
n hops: The maximum number of hops to allow.
n host: The IP address of the destination host.
n interface: The interface for sending the route trace.
n size: The size, in bytes, of the message to send.
n src-ip: Use this source IP address for outgoing packets.
n timeout: The maximum number of seconds to wait for a response from a hop.
Example
This example shows using traceroute to verify that the TransPort device can route to host 8.8.8.8
(www.google.com) through the default gateway. The command output shows that 15 routing hops
were required to reach the host:
digi.router> show route
