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 by the -m
keyword.
Number of bytes of a probe packet.
During the execution of the command, press Ctrl+C to abort the tracert
operation.
Probe result of the probe packets whose TTL is 1, including the domain name
(or IP address, if the domain name is not configured) of the first hop, and the
round-trip time of the three probe packets.
The number of packets that can be sent in each probe can be set through the
-q keyword.
ICMP timeout packets on an MPLS network, carrying 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 in
another label stack.
