Packets Lost: The number of packets unaccounted for, shown in total and as a percentage of total packets sent. This statistic may be updated during the Ping test, and may not be accurate until after the test is over. However, if an escalating one-to-one correspondence is seen between Packets Out and Packets Lost, and Packets In is noticeably lagging behind Packets Out, the destination is probably unreachable. In this case, use

STOP PING.

Round Trip Time (Min/Max/Avg): Statistics showing the minimum, maximum, and average number of seconds elapsing between the time each Ping packet was sent and the time its corresponding return Ping packet was received.

The time-to-live (TTL) value for each Ping packet sent by the Netopia R9100 is 255, the maximum allowed. The TTL value defines the number of IP routers that the packet can traverse. Ping packets that reach their TTL value are dropped, and a “destination unreachable” notification is returned to the sender (see the table on the previous page). This ensures that no infinite routing loops occur. The TTL value can be set and retrieved using the SNMP MIB-II ip group’s ipDefaultTTL object.

Trace Route

You can count the number of routers between your Netopia Router and a given destination with the Trace Route utility.

In the Statistics & Diagnostics screen, select Trace Route and press Return. The Trace Route screen appears.

 

Trace Route

Host Name or IP Address:

 

Maximum Hops:

30

Timeout (seconds):

5

Use Reverse DNS:

Yes

START TRACE ROUTE

Enter the IP Address/Domain Name of a host.

Trace route to a network host.

To trace a route, follow these steps:

1.Select Host Name or IP Address and enter the name or address of the destination you want to trace.

2.Select Maximum Hops to set the maximum number of routers to count between the Netopia Router and the destination router, up to the maximum of 64. The default is 30 hops.

3.Select Timeout (seconds) to set when the trace will timeout for each hop, up to 10 seconds. The default is 3 seconds.
