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. Loopback interfaces
are not supported on the N1100-ON Series switches.
Examples
The following example discovers the routes that packets will actually take
when traveling to the destination specified in the command.
(console)# traceroute ipv6 2001::2 init-ttl 1 max-ttl 4 max-fail 0 interval 1
count 3 port 33434 size 43
Traceroute to 2001::2, 4 hops max, 43 byte packets:
1 2001::2 708 msec 41 msec 11 msec
2 2001::2 12 msec 13 msec 12 msec
3 2001::2 14 msec 9 msec 11 msec
