Parameters -f first-hop: Specifies the first hoplimit (the allowed number of hops for the first packet). The first-hop argument is in the range of 1 to 255. The default value is 1. The first hoplimit must be less than the value of the max-hops argument. -m max-hops: Specifies the maximum number of hops allowed for a packet. The max-hops argument is in the range of 1 to 255. The default value is 30. It must be greater than the value of the first-hop argument. -p port: Specifies the UDP port number of the destination. The port argument is in the range of 1 to 65535. The default value is 33434. It is unnecessary to modify this option. -q packet-number: Specifies the number of probe packets sent each time. The packet-number argument is in the range of 1 to 65535. The default value is 3. -vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the destination belongs, where the vpn-instance-name argument 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 (in milliseconds) of the reply packet of a probe packet. The timeout argument is in the range of 1 to 65535. The default value is 5000 milliseconds. host: IPv6 address or host name (a string of 1 to 253 characters) for the destination. Usage guidelines After having identified network failure with the ping ipv6 command, you can use the tracert ipv6 command to locate failed nodes. The output of the tracert ipv6 command includes IPv6 addresses of all the Layer 3 devices that 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 # Display the path that the packets traverse from source to destination (2001:3::2). tracert ipv6 2001:3::2 traceroute to 2001:3::2(2001:3::2), 30 hops at most, 60 byte packets, press CTRL_C to break 1 2001:1::2 0.661 ms 0.618 ms 0.579 ms 2 2001:2::2 0.861 ms 0.718 ms 0.679 ms 3 2001:3::2 0.822 ms 0.731 ms 0.708 ms Table 4 Command output Field traceroute to 2001:3::2 hops at most byte packets 1 2001:1::2 0.661 ms 0.618 ms 0.579 ms Description Display the route that the IPv6 packets traverse from the current device to the device whose IP address is 2001:3:2. Maximum number of hops of the probe packets, which can be set by the -m keyword. Number of bytes of a probe packet. Probe result of the probe packets whose hoplimit is 1, including the IPv6 address of the first hop, and the roundtrip time of three probe packets. The number of packets that can be sent in each probe can be set by the -q keyword. 14
