5.16.10. Traceroute
5.16.10.1. traceroute
Use the traceroute command to discover the routes that packets actually take when traveling to their
destination through the network on a hop-by-hop basis. Traceroute continues to provide a synchronous
response when initiated from the CLI.
Format traceroute [vrf <vrf-name>] <ip-address | hostname> [initTtl <initTtl>] [maxTtl <maxTtl>] [maxFail
<maxFail>] [interval <interval>] [count <count>] [port <port>] [size <size>] [source {< ip-address> |
<slot/port> | loopback <loopback-id> | serviceport | tunnel <tunnel-id> | vlan <vlan-id>}]
Default The default initTtl is 1.
The default maxTtl is 30.
The default maxFail is 5.
The default interval is 3 seconds.
The default count is 3.
The default port is 33434.
The default size is 0 bytes.
Mode Privileged EXEC
Parameter
Definition
vrf-name
The name of the virtual router in which to initiate traceroute. Only hosts
reachable from within the VRF instance can be tracerouted. If a source parameter
is specified in conjunction with a vrf parameter, it must be a member of the VRF.
The ipv6 parameter cannot be used in conjunction with the vrf parameter.
initTtl
Use initTtl to specify the initial time-to-live (TTL), the maximum number of router
hops between the local and remote system. Range is 0 to 255.
maxTtl
Use maxTtle to specify the maximum TTL. Range is 1 to 255.
maxFail
Use maxFail to terminate the traceroute after failing to receive a response for
this number of consecutive probes. Range is 0 to 255.
port
Use the optional port parameter to specify destination UDP port of the probe.
This should be an unused port on the remote destination system. Range is 1 to
65535.
count
Use the count parameter to specify the number of probes per hop. The range for
count is 1 to 10.
interval
Use the interval parameter to specify the time between probes, in seconds. If
traceroute does receive a response to a probe within this interval, then it sends
the next probe immediately. Range is 1 to 60 seconds.
size
Use the size parameter to specify the size of probe packets, in bytes. Range is 0
to 39936 bytes.
source
Use the source parameter to specify the source IP/IPv6 address or interface to
use for the traceroute.
