User Guidelines
Traceroute operates by sending a sequence of Internet Control Message
Protocol (ICMP) echo request packets. The time-to-live (TTL) value, is used
in determining the intermediate routers through which the packet flows
toward the destination address. Routers decrement a packet’s TTL value and
discard packets whose TTL equals 0. On discarding a packet, the router
returns an ICMP time exceeded message to the source.
Examples
The following example discovers the routes that packets will actually take
when traveling to the destination specified in the command.
(console) # traceroute 10.240.10.115 init-ttl 1 max-ttl 4 max-fail 0 interval
1 count 3 port 33434 size 43
Traceroute to 10.240.10.115, 4 hops max, 43 byte packets:
1 10.240.4.1 708 msec 41 msec 11 msec
2 10.240.10.115 0 msec 0 msec 0 msec
Hop Count = 1 Last TTL = 2 Test attempt = 6 Test Success = 6
traceroute ipv6
Use the traceroute command in Privileged EXEC mode to discover the IP
routes that packets actually take when traveling to their destinations.

•
ipv6address
—
Valid IPv6 address of the destination host.
•
hostname
—
Hostname of the destination host. (Range: 1–158 characters). The
command allows spaces in the host name when specified in double quotes. For
example,
console(config)#snmp-server host "host name"
•
initTtl
—
The initial time-to-live (TTL); the maximum number of router hops
between the local and remote system (Range: 0–255). the default is 1.
