User Guidelines
Use of the optional VRF parameter executes the command within the
context of the VRF-specific routing table.
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.
Only IPv4 addresses are supported with the vrf parameter. The vrf parameter
is only available on the N3000/N3100/N4000 switches.
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 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
