Parameters
-f first-hop: Specifies the TTL value of the first packet. The value range is 1 to 255, and the default is
1. The value must be no greater than the value of the max-hops argument.
-m max-hops: Specifies the maximum number of hops allowed for a packet. The value range is 1 to
255, and the default is 30. The value must be no smaller than the value of the first-hop argument.
-p port: Specifies an invalid UDP port of the destination. The value range is 1 to 65535, and the
default is 33434.
-q packet-number: Specifies the number of probe packets sent each time. The value range is 1 to
65535, and the default is 3.
-t traffic-class: Specifies the traffic class value in an IPv6 probe packet. The value range is 0 to 255,
and the default is 0.
-vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the destination
belongs. The vpn-instance-name argument represents the VPN instance name, a case-sensitive
string of 1 to 31 characters. If the destination is on the public network, do not specify this option.
-resolve-as: Specifies a routing table for AS resolution. Tracert searches the specified routing table
for the AS that each hop along the path belongs to. If you do not specify this keyword, the global
routing table is used. If the AS information is found, this command displays the AS number next to
the address of the hop in the probe result.
•
global: Specifies the global routing table.
•
none: Disables AS resolution.
•
vpn: Specifies the VPN routing table.
-w timeout: Specifies the timeout time (in milliseconds) of the reply packet of a probe packet. The
value range is 1 to 65535, and the default is 5000.
host: Specifies the IPv6 address or host name of the destination. The host name is a
case-insensitive string of 1 to 253 characters. It can contain letters, digits, and special characters
such as hyphen (-), underscore (_), and dot (.).
Usage guidelines
After identifying network failure with the ping ipv6 command, you can use the tracert ipv6
command to locate failed nodes.
If the destination address is on the public network, you do not need to specify the -resolve-as
keyword to obtain the AS information. The device automatically uses the global routing table for AS
resolution.
If the destination address is on a private network, address information of intermediate hops might be
stored in either the global routing table or the VPN routing table. To learn the AS path that the
packets traverse, execute the tracert ipv6 command twice, once with the -resolve-as global
keywords and again with the -resolve-as vpn keywords.
The output from 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. The reason might be 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.
