Ping
The
Ping
function uses the
ping
command to give users a simple but powerful tool for
troubleshooting network problems. The function’s most unique feature is that even though the
ping command is entered from the user’s PC keyboard, the actual ping command originates from
PT-7728 itself. In this way, the user can essentially sit on top of PT-7728 and send ping commands
out through its ports.
To use the Ping function, type in the desired IP address, and then press
Enter
from the Console
utility, or click
Ping
when using the Web Browser interface.
Using Monitor
You can monitor statistics in real time from PT-7728’s web console and serial console.
Monitor by Switch
Access the Monitor by selecting
System
from the left selection bar. Monitor by System allows the
user to view a graph that shows the combined data transmission activity of all of PT-7728’s 18
ports. Click one of the four options—
Total Packets
,
TX Packets
,
RX Packets
, or
Error
Packets
—to view transmission activity of specific types of packets. Recall that TX Packets are
packets sent out from PT-7728, RX Packets are packets received from connected devices, and
Error Packets are packets that did not pass TCP/IP’s error checking algorithm. The Total Packets
option displays a graph that combines TX, RX, and TX Error, RX Error Packets activity. The
graph displays data transmission activity by showing
Packets/s
(i.e., packets per second, or pps)
versus
sec.
(seconds). In fact, three curves are displayed on the same graph:
Uni-cast
packets (in
red color),
Multi-cast
packets (in green color), and
Broad-cast
packets (in blue color). The graph
is updated every few seconds, allowing the user to analyze data transmission activity in real-time.
