Parameter
-a source-ip: Sets the source IP address used by this command.
-f first-TTL: Sets the initial TTL of the packets to be sent, so that this command displays
the addresses of only those gateways on the path whose hop counts are not smaller
than the hop count specified by the first-TTL argument. For example, if the first-TTL
argument is three, the command displays the addresses of the gateways from the third
hop. The first-TTL argument ranges from 1 to 255 and defaults to 1.
-m max-TTL: Sets the maximum TTL value of the packets to be sent. After the
command sends a packet with the maximum TTL, it will not send any more packets.
With this argument, this command displays the addresses of only those gateways from
the source destination to the hop count specified by the argument. For example, if the
max-TTL argument is 5, the command displays the addresses of the gateways from the
source to the fifth count. The max-TTL argument ranges from 1 to 255 and defaults to
30.
-p port: Sets the destination port of the packets to be sent. The port argument ranges
from 0 to 65535 and defaults to 33434. Generally, you need not change the argument.
