Prerequisite(s):  
Classic mode must be enabled.
 
To use the Ping/Trace Route tool:
On the Classic tab, in the Tools group, click Ping/Trace Route.
 
See Table 11 for more information.
Table 11. Ping/Trace Route options
Internet Address
Allows you to specify the Internet address to ping, or the address to which the route will be traced.
Save button
Allows you to save the present Internet address.
Delete button
Selecting an address in the saved addresses box and clicking this button allows you to delete the address from the saved addresses.
Ping
Allows you to select the Internet address to ping and the results to be displayed in the main Ping/Trace Route display area. To ping an address is to send out an ICMP echo request to that address. If the station is operating normally, it will respond, unless it is behind a firewall that prevents such response.
Trace Route
Allows you to select a route from the Observer personal computer to the specified Internet address to be traced.
Timeout(sec)
Allows you to specify the number of seconds that Observer will wait for a response before assuming that the packet Observer sent was either not received or not responded to.
Packets
If the Ping option is selected, this box specifies the number of ping packets or ICMP echo requests that will be sent. When the Trace Route option is selected, this option has no effect and will be grayed out.
Packet size
If the Ping option is selected, this edit box selects the number of ping packets or ICMP echo requests that will be sent. When the Trace Route option is selected, this option will not be activated.
