-f first-ttl: Specifies the first TTL, that is, the allowed number of hops for the first packet,

in the range 1 to 255. It defaults to 1 and must be less than the maximum TTL.

-m max-ttl: Specifies the maximum TTL, that is, the maximum allowed number of hops

for a packet, in the range 1 to 255. It defaults to 30 and must be greater than the first

-p port: Specifies the UDP port number of the destination device, in the range 1 to

65535. The default value is 33434. It is unnecessary to modify this parameter.

-q packet-number: Specifies the number of probe packets sent each time, in the range

1 to 65535, defaulting to 3.

-w timeout: Specifies the timeout time of the probe packets, in the range 1 to 65535, in
