Use the traceroute command to discover the routers that packets traverse
when traveling to their destination.
Syntax
traceroute ipv6 ipv6address|hostname [init-ttl initTtl] [max-ttl maxTtl]
[max-fail maxFail] [interval interval] [count count] [port port] [size
size][source {src-ip-address|vlan vlan-id|loopback loopback-id}]
• ipv6address—Valid IPv6 address of the destination host.
• hostname—Hostname of the destination host. (Range: 1–256
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: 1–255). the default is
1.
• maxTtl—The largest TTL value that can be used (Range:1–255). The
default is 30. This must be larger or equal to the value specified in
initTtl.
• maxFail—Terminate the traceroute after failing to receive a response for
this number of consecutive probes (Range: 1–255).
• interval—The timeout period. If a response is not received within this
period of time, then traceroute considers that probe a failure (printing
*) and sends the next probe. If traceroute does receive a response to a
probe, then it sends the next probe immediately. (Range: 1–60 seconds).
The default is 3.
• count—The number of probes to be sent at each TTL level (Range:1–
10).
• port—The destination UDP port of the probe. This should be an
unused port on the remote destination system (Range: 1–65535).
