Parameters
-a source-ip: Specifies the source IP address of a tracert packet. It must be a legal IP
address configured on the device.
-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
TTL.
-p port: Specifies the UDP port number of the destination device, in the range 1 to
65535. The default value is 33434. You do not need to modify this parameter.
-q packet-number: Specifies the number of probe packets sent each time, in the range
1 to 65535. The default value is 3.
-w timeout: Specifies the packet timeout time, in the range 1 to 65535, in milliseconds.
