Switch Management Commands 2242toward the destination address. Routers decrement a packet’s TTL value anddiscard packets whose TTL equals 0. On discarding a packet, the routerreturns an ICMP time exceeded message to the source.The VRF identified in the parameter must have been previously created or anerror is returned.Only IPv4 addresses are supported with the vrf parameter. The vrf parameteris only available on the N3000/N3100/N4000 switches.Loopback interfaces are not supported on the N1100-ON Series switches.ExamplesThe following example discovers the routes that packets will actually takewhen traveling to the destination specified in the command.(console)# traceroute 10.240.10.115 init-ttl 1 max-ttl 4 max-fail 0 interval1 count 3 port 33434 size 43Traceroute to 10.240.10.115, 4 hops max, 43 byte packets:1 10.240.4.1 708 msec 41 msec 11 msec2 10.240.10.115 0 msec 0 msec 0 msecHop Count = 1 Last TTL = 2 Test attempt = 6 Test Success = 6Command HistorySyntax updated in 6.4 release.traceroute ipv6Use the traceroute command to discover the routers that packets traversewhen traveling to their destination.Syntaxtraceroute [ipv6] ipv6address|hostname [init-ttl initTtl] [max-ttl maxTtl][max-fail maxFail] [interval interval] [count count] [port port] [sizesize][source {src-ip-address|vlan vlan-id|loopback loopback-id}]• ipv6address—Valid IPv6 address of the destination host.• hostname—Hostname of the destination host.
