Parameters
-f first-ttl: Specifies the first TTL, or, the allowed number of hops for the first packet. It ranges from 1 to 255
and defaults to 1, and must be less than the maximum TTL.
-m max-ttl: Specifies the maximum TTL, or, the maximum allowed number of hops for a packet. It ranges
from 1 to 255 and defaults to 30, and must be greater than the first TTL.
-p port: Specifies the UDP port number of the destination, which ranges from 1 to 65535 and defaults to
33434. It is unnecessary to modify this parameter.
-q packet-number: Specifies the number of probe packets sent each time, which ranges from 1 to 65535
and defaults to 3.
Description
Display the route that the IP packets traverse from the current device to
the device whose IP address is 1.1.2.2.
Maximum number of hops of the probe packets, which can be set
through the -m keyword.
Number of bytes of a probe packet.
During the execution of the command, you can press Ctrl+C to abort
the tracert operation.
Probe result of the probe packets whose TTL is 1, including the IP
address of the first hop and the roundtrip time of three probe packets.
Number of packets that can be sent in each probe can be set through
the -q keyword.
ICMP timeout packets on an MPLS network, carry MPLS label
information:
•
Label—Label value that is used to identify a forwarding
equivalence class (FEC).
•
Exp—Reserved, usually used for class of service (CoS).
•
TTL—TTL value.
•
S—MPLS supports multiple levels of labels. Value 1 indicates that
the label is at the bottom of the label stack, and value 0 indicates
that the label is not at the bottom of the label stack.
