traceroute6
Purpose This command is used to trace the IPv6 routed path between the switch and a destination
end station.
Syntax
traceroute6 <ipv6addr> {ttl <value 1-60> | port <value 30000-64900> | timeout <sec 1-
65535> | probe <value 1-9>}
Description To track the route of an IPv6 packet, traceroute6 launches UDP probe packets with a small
TTL (time to live) and then listens for an ICMP "time exceeded" reply from a gateway. Probes
start with a TTL of one and increase by one until either an ICMP "port unreachable" is
returned, indicating that the packet reached the host, or the maximum number of hops is
exceeded. At each TTL setting, one probe are launched (the number can be changed by
specifying the parameter “probe”) and traceroute prints a line showing the round trip time and
the address of the gateway of each probe, or time out of each probe. If there is no response
within the 5 seconds timeout interval, an asterisk (*) is printed for that probe.
Parameters
ipv6addr - IPv6 address of the destination end station.
ttl <value 1-60> - The time to live value of the trace route request. This is the maximum
number of routers that a trace route v6 packet can cross, while seeking the network path
between two devices. The range for the TTL is 1 to 60 hops.
port <value 30000-64900> - Specify the destination UDP port number. The UDP port range is
from 30000 to 64900.
timeout <sec 1-65535> - Define the timeout period while waiting for a response from the
remote device. A value of 1 to 65535 seconds can be specified. The default is 5 seconds.
probe <value 1-9> - Specify the number of probe packets for each hop. The default is 1.
Note: The probe will be terminated once the destination is reached.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To trace the IPv6 routed path between the switch and 3000::1:
