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>
.mgmt
Specifies use of the management interface.
Authority

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.
