Analyzing Connectivity Issues Using the Ping, Trace Route, or NS Lookup Tools
Analyzing Configuration Using TraceRoute
The Traceroute tool helps you to determine the route that packets will take to their destination. The tool
prints the result of each probe sent. Every line of output corresponds to a TTL value in increasing order.
Traceroute can return useful information about TCP/IP connectivity across your network. The following
table shows some of the codes that can be returned by the Traceroute utility, along with their possible
cause.
Step 1 In Device view, select Tools > Ping, TraceRoute and NS Lookup . . ..
The Ping, TraceRoute and NS Lookup dialog box appears.
Tip From within the Event Manager, you can right-click on an event to open the TraceRoute page
and trace the route of the associated device.
Step 2 Select the Trace Route tab.
The Trace Route page appears.
Step 3 From the device selector, select the host from which the route is traced.
Step 4 Enter the IPv4 Address/Hostname to specify the address or name of the host to which the route is
traced.
Alternatively, click Select to choose a host network/host object that defines the IP address.
Step 5 Specify values, as required, for the following:
