Parameters

-f first-ttl: Specifies the first TTL, or, the allowed number of hops for the first packet. It is in the range of 1 to 255 and defaults to 1, and must be less than the maximum TTL.

-m max-ttl: Specifies the maximum TTL (the maximum allowed number of hops for a packet). It is in the range of 1 to 255 and defaults to 30, and must be greater than the first TTL.

-p port: Specifies the UDP port number of the destination, which is in the range of 1 to 65535 and defaults to 33434.

-q packet-number: Specifies the number of probe packets sent each time, which is in the range of 1 to 65535 and defaults to 3.

-w timeout: Specifies the timeout time of the reply packet of a probe packet, which is in the range of 1 to 65535 milliseconds and defaults to 5000 milliseconds.

host: Specifies the IPv6 address or host name of the destination, a string of 1 to 255 characters.

-tos tos: Specifies the ToS value for an IPv6 tracert packet, which is in the range of 0 to 255 and defaults to 0.

Description

Use tracert ipv6 to view the path the IPv6 packets traverse from source to destination.

In the event of network failure, you can use this command to determine the failed nodes.

Output from the tracert ipv6 command includes IPv6 addresses of all the Layer 3 devices the packets traverse from source to destination. Asterisks (* * *) are displayed if the device cannot reply with an ICMP error message (probably because the destination is unreachable or sending ICMP timeout/destination unreachable packets is disabled).

To abort the tracert operation during the execution of the command, press Ctrl+C.

Examples

# View the path the packets traverse from source to destination with IPv6 address 2001::1.

<Sysname> tracert ipv6 2001::1
 traceroute to 2001::1  30 hops max,60 bytes packet, press CTRL_C to break
 1  2001::1 3 ms <1 ms 19 ms
