Parameter Description
interval
Use the optional interval parameter to specify the time between probes, in seconds.
If a response is not received within this interval, then traceroute considers that probe a
failure (printing *) and sends the next probe. If traceroute does receive a response to a
probe within this interval, then it sends the next probe immediately. Range is 1 to 60
seconds.
count
Use the optional count parameter to specify the number of probes to send for each TTL
value. Range is 1 to 10 probes.
port
Use the optional port parameter to specify destination UDP port of the probe. This
should be an unused port on the remote destination system. Range is 1 to 65535.
size
Use the optional size parameter to specify the size, in bytes, of the payload of the Echo
Requests sent. Range is 0 to 65507 bytes.
source
Use the optional source parameter to specify the source IP address or interface for the
traceroute.
The following are examples show the CLI output for this command.
