-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
TTL.
-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
