ipv4	Specifies IPv4 transport.
ipv6	Specifies IPv6 transport.
`host`	Specifies the host of the destination endstation.
ttl `number`	Configures the switch to trace up to the time-to-live number of the switch.
from `from`	Uses the specified source address in the ICMP packet. If not specified, the address of the transmitting interface is used.
port `port`	Specifies the UDP port number.
icmp	Configures the switch to send ICMP echo messages to trace the routed path between the switch and a destination endstation.

Usage Guidelines

Use this command to trace the routed path between the switch and a destination endstation.

Each router along the path is displayed.

Example

The following example enables the traceroute function to a destination of 123.45.67.8:

traceroute 123.45.67.8

The following is sample output that displays when the traceroute fails:

traceroute to 10.209.10.37, 30 hops max
1  0.0.0.0                                      * !u        * !u        * !u
--- Packet Response/Error Flags ---
(*) No response, (!N) ICMP network unreachable, (!H) ICMP host unreachable,
(!P) ICMP protocol unreachable, (!F) ICMP fragmentation needed,
(!S) ICMP source route failed, (!u) Transmit error, network unreachable,
(!f) Transmit error, fragmentation needed, (!t) General transmit error
