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 R3100 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 above). 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.

Telnet client

The Telnet client mode replaces the normal menu mode. Telnet sessions can be cascaded, that is, you can initiate a Telnet client session when using a Telnet console session. To activate the Telnet client, select Telnet from the Utilities & Diagnostics menu.
