Chapter 6 Network

STEP 4

STEP 5

Configure any of the following options:

First Hop — you can choose which is the first hop that you get information about. For example, if you already know about the first four hops, enter 5

Probe Type — select the communications protocol or the traceroute: UDP or ICMP

Max Hops — the maximum number of hops for the traceroute

Print Name — whether or not you want the trace route to query and display the DNS names of the routers

Port Base — the port number from which the packet is sent. Leave as default value

Max Number of Timeouts — the maximum number of timeouts after which the traceroute stops

Number Of Queries — the number of packets that will be sent to each hop

Max Wait — the maximum time in milliseconds the traceroute will wait for a response from the destination host before stopping

Calculate Checksum — whether or not to use checksums

Click Start Traceroute.

The device sends a trace route request to the specified device and a message similar to the following is displayed:

traceroute to 192.168.1.251, 30 hops max, 38 byte packets

If the device is accessible and functioning correctly, a message similar to the following is displayed which displays the network hops. Each hop may take a few seconds to complete:

1.router1 (192.168.1.252) 1.292ms, 1.343ms, 1.810ms 2.router2 (192.168.1.253) 26.027ms, 27.156ms, 44.902ms 3.router3 (192.168.1.254) 24.323ms, 24.854ms, 30.096ms 4.router4 (192.168.1.255) 27.303ms, 33.639ms

If the device is not accessible, or is not functioning correctly, only the hops that worked are displayed.

Note Some network environments block trace route traffic on the network. The TraceRoute request may therefore fail even if the network device is operating normally.
