• count —The number of probes to be sent at each TTL level (Range:1–10).
•
port —The destination UDP port of the probe. This should be an unused
port on the remote destination system (Range: 1–65535).
•
size —The size, in bytes, of the payload of the Echo Requests sent (Range:
0–39936 bytes).

src-ip-address —The IPv4 source address to use in the ICMP echo request
packets.
•
vlan —A valid VLAN interface.
•
loopback-id —A configured loopback ID

User Guidelines
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/N4000 switches.
