traceroute [protocol] dest-ip[source source-ip] [length bytes ]

[timeout time ] [hops hops ] [interface intf-type intf-num [.sub-intf-num]]

Minimum Access Level: Operator

Command Mode: Standard

This command performs the TraceRoute test to the specified destination IP address. The general format of the TraceRoute results is seen as follows:

Tracing route to x.x.x.x over a max of nn hops, with nnn byte packet:

1 <100ms <100ms <100ms x.x.x.x

2 <100ms <100ms <100ms x.x.x.x

3 <200ms <200ms <200ms x.x.x.x

4 <200ms <200ms <200ms x.x.x.x

The first column is the hop number, which is the Time to Live (TTL) value set in the IP packet header. Each of the three next columns contains the round-trip time in 100ms intervals for each attempt to reach the destination with that TTL value. If no response is received, an * (asterisk) is displayed in place of the roundtrip time. The fifth column is the IP address of the responding system. If no response is received for a hop, the last column is blank.

protocol – The protocol of the echo message for TraceRoute: ip.

dest-ip– Address of the device to TraceRoute.

source – The source IP address. The default source IP address is the IP address for the interface on which packets are routed to the destination IP address.

source-ip– The source IP address used in the TraceRoute test. The default source IP address will be the IP address for the interface on which packets are routed to the destination IP address. The source IP address specified must be an IP address assigned to an interface or sub-interface.

length – Specify the length of packets sent.

bytes – Number of data bytes. Range = 0–1500. Default = 64.

timeout – Specify the time in seconds before the TraceRoute test is abandoned.

time – Number of seconds before the TraceRoute test is abandoned. Range = 1–30. Default = 5 seconds.

hops – Specify the maximum number of hops to be tested.

hops – The maximum number of hops to be tested. Range = 1–128. Default = 8.

interface – Specify the target interface. The default target interface is the interface on which packets are routed to the destination IP address.

intf-type– Two interface types are supported:

Ethernet – IEEE 802.3 interface

Serial – Frame relay serial interface

intf-num– The interface index number for the Ethernet and the Serial interfaces: 0.

sub-intf-num– The sub-interface number is only supported on the Network interface (Serial 0). The following sub-interface numbers are supported: 0–4,294,967,295.
