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. The VRF identified in the parameter must have been previously created or an error is returned. The hostname parameter may be a fully or partially qualified domain name. A hostname consists of a series of labels separated by periods. Each label may be a maximum of 63 characters in length. The maximum length of the hostname parameter is 256 characters. Refer to RFC 1035 Section 2.3.1 for more information. Only IPv4 addresses are supported with the vrf parameter. The vrf parameter is only available on the N3200-ON switch. Loopback interfaces are not supported on the N1108EP-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 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 Command History Syntax updated in 6.4 release. traceroute ipv6 Use the traceroute command to discover the routers that packets traverse when traveling to their destination.
