Command context

Operator (>) or Manager (#)

Parameters

IPv6-address

Specifies the IPv6 address of the device to use traceroute.

hostname

Specifies the hostname of the device to use traceroute.

dstport <NUMBER>

Specifies the destination port, <1-34000>. Default: 33434

maxttl <NUMBER>

Specifies the maximum number of hops to reach the destination, <1-255>. Default: 30

probes <NUMBER>

Specifies the number of probes, <1-5>. Default: 3

timeout <TIME>

Specifies the traceroute timeout in seconds, <1-60>. Default: 3 seconds

vrf <VRF-NAME>

Specifies the virtual routing and forwarding (VRF) to use, <VRF-NAME>.

Usage

Traceroute is a computer network diagnostic tool for displaying the route (path), and measuring transit delays of packets across an Internet Protocol (IP) network. It sends a sequence of User Datagram Protocol (UDP) packets addressed to a destination host. The time-to-live (TTL) value, also known as hop limit, is used in determining the intermediate routers being traversed towards the destination.
