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 Router is 255, the maximum allowed. The TTL value
defines the number of IP gateways 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 gateways between your Motorola Netopia
Trace Route utility.
In the Statistics & Diagnostics screen, select Trace Route and press Return. The Trace Route screen appears.
Host Name or IP Address:
Maximum Hops:
Timeout (seconds):
Use Reverse DNS:
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 gateways to count between the Motorola Netopia
Router and the destination gateway, 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.
