Using the Monitor
You can monitor statistics in real time from the IE-SW-VL08M’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 the
IE-SW-VL08M’s ports. Click on 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 the switch, 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 Error Packet activity. The four graphs (Total
Packets, TX Packets, RX Packets, and Error Packets) have the same form, so we show only the Total
Packets graph here. 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.
Monitor by Port
Access the Monitor by Port function by selecting
ALL 10/100M Ports
or
Porti
, in which
i
= 1, 2, …
8, etc., from the left pull-down list. The
Porti
options are identical to the Monitor by System
function discussed previously, in that users can view graphs that show Total Packets, TX Packets,
RX Packets, or Error Packets activity, but in this case, only for an individual port.
The
All 10/100M
Ports
option is essentially a graphical display of the individual port activity that can be viewed with
the Console Monitor function discussed above. The All 10/100M Ports option shows three vertical
bars for each port. The height of the bar represents
Packets/s
for the type of packet, at the instant the
bar is being viewed. That is, as time progresses, the height of the bar moves up or down so that the
user can view the change in the rate of packet transmission. The red colored bar shows
Uni-cast
packets, the green colored bar shows
Multi-cast
packets, and the blue colored bar shows
Broad-cast
packets. The graph is updated every few seconds, allowing the user to analyze data
transmission activity in real-time.
