R3303-HP HSR6800 Routers Network Management and Monitoring Command Reference

10
-p port: Specifies the UDP port number of the destination. The value range is 1 to 65535, and the default
is 33434. You do not need to modify this parameter.
-q packet-number: Specifies the number of probe packets sent each time. The value range is 1 to 65535,
and the default is 3.
-vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the destination belongs,
where vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the destination is on the public
network, do not specify this option.
-w timeout: Specifies the timeout time of the reply packet of a probe packet, in milliseconds. The value
range is 1 to 65535, and the default is 5000.
host: IPv6 address or host name of the destination, which is a string of 1 to 46 characters.
Usage guidelines
In the event of network failure, you can use the tracert 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
# View the path the packets traverse from source to destination with IPv6 address 2001::1 in VPN 1.
<Sysname> tracert ipv6 –vpn-instance vpn1 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
