DESCRIPTION
Enter the number of seconds (5~3600) between data samplings the ENC
retrieves from the selected device. Click Start Polling to have the ENC start to
retrieve data from the device or Stop Polling to stop it. You have to stop
pollings first if you want to change the settings for graphic display.
Select whether to display network statistics as a Line, Bar, or Pie graph.
Select this to use Delta value as the method of obtaining the sample value. Clear
this to use Absolute value as the method instead.
Delta means the value is from the data sampled in each configured time
interval. Absolute means the sampling value is accumulated since it started.
Select this to display the total number of octets received/transmitted on the
port(s).
Select this to display the total number of all good packets received/transmitted
on the port(s).
Select this to display the total number of packets that were dropped by the
port(s).
Select this to display the total number of good broadcast packets received/
transmitted on the port(s).
Select this to display the total number of good multicast packets received/
transmitted on the port(s).
Select this to display the total number of good unicast packets received/
transmitted on the port(s).
Select this to display the number of packets dropped by the port(s) because
they were less than 64 octets long, and contained a valid FCS.
Select this to display the number of packets received/transmitted on the port(s)
because they were less than 64 octets long, and contained an invalid FCS,
including non-integral and integral lengths.
Select this to display the number of packets dropped by the port(s) because
they were longer than 1518 octets and contained an invalid FCS, including
alignment errors in the graph of this section.

Select this to display the number of packets for which transmission failed due to
collisions. Excessive collision is defined as the number of maximum collisions
before the retransmission count is reset.
Select this to display the number of frames received/transmitted on the port(s)
because they were 64 to 1518 (non VLAN) or 1522 (VLAN) octets long but
contained an invalid FCS and a non-integral number of octets.
